BreezeSharp client and the TimeSpan issue - breeze

We're unable to re-hydrate the Breeze# client object which has TimeSpan? properties and if prop value is not null
BreezeServer returns the TimeSpan in the ISO 8601 format (eq. "PT8H") but as TimeSpan.Parse() expects different format [ws][-]{ d | [d.]hh:mm[:ss[.ff]] }[ws] a System.FormatException is thrown ("String was not recognized as a valid TimeSpan") in the Breeze.Sharp.JsonEntityConverter while parsing objects.
Is this a known issue? IS there any workaround for it?

Ok, this was a bug and has been fixed in the lastest version on the breeze.sharp GitHub repo, it will also go out in the next release, probably sometime next week. Please confirm whether or not it corrects your issue.

I got an error when I open an existing build definition and select Process
Parameter Logging Verbosity: cannot convert value 'Detailed' of type Microsoft.TeamFoundation.Build.Workflow.BuildVerbosity to type Microsoft.TeamFoundation.Build.Workflow.BuildVerbosity, reset to default.
I am using VS 2012 connect to TFS2012. How to fix it? Thanks.

CSOM 2013 error: Unable to cast object of type 'System.Collections.Generic.Dictionary

I'm using this code to loop columns of a SharePoint 2013 List.
currentContext.Load(currentList.Fields);
currentContext.ExecuteQuery();
foreach (Field f in currentList.Fields) {
}
No problem with normal columns. But, when I arrive to a lookup column I have this error:
"Unable to cast object of type
'System.Collections.Generic.Dictionary`2[System.String,System.Object]'
to type 'Microsoft.SharePoint.Client.Field'."
I found for example this discussion
This issue came when we were working with TaxonomyFieldValue fields. For us changing references was not an option. This helped:
TaxonomyItem dummy = new TaxonomyItem(web.Context, null);
It will force program to load adequate libraries forcing correct type in runtime.
I had this same issue and updating the references fixed it for me. This question helped me figure it out.
I went from version 14 of "Microsoft.SharePoint.Client" and "Microsoft.SharePoint.Client.Runtime" to version 16 and no longer had the error.

HHVM non-deterministic behaviour of the typechecker

I've noticed that calling hh_client is not always returning correct result. For example: I have following pieces of code:
backend\ConvertMessage.hh:
<?hh // strict
namespace ApiBackend\ConvertMessage {
enum Status: int {
success = 0;
// ... error codes
};
// ... some other classes
};
other place in project:
throw new \SoapFault(
'Server',
\ApiBackend\ConvertMessage\Status::getNames()[$result->status]
);
Sometimes, after doing some changes in project I get following error message: Could not find static method getNames in type ApiBackend\ConvertMessage\Status (Typing[4090])
When I remove a semicolon after one of closing curly brackets, hh_client stops displaying error. But when I insert semicolon back on its place, typechecker still gives me No errors! message.
This is not the only file that causes this problem - it happens to all enums.
It seems to me that it is problem with some cache of either hh_client or hh_server.
Thanks in advance for helping me with solving this problem (and sorry if my english is not too good).
You are probably using an outdated version of HHVM. This problem sounds an awful lot like this race condition, which was fixed in HHVM 3.5.0 and newer (and was backported into the 3.3.3 LTS release). Notably, 3.4.x still had the bug.
What version of HHVM are you using?

QBO - Error while quering TaxRate with QB V3 API

I get an error while querying TaxeRate from QBO using QB API V3.
Here is my request:
String query = "Select * FROM TaxRate ";
List<? extends IEntity> result = service.executeQuery(query).getEntities();
below is what i get in return
Some other Exception in SDK or network happened: org.codehaus.jackson.map.JsonMappingException: Can not construct instance of com.intuit.ipp.data.SpecialTaxTypeEnum from String value 'NO_TAX': value not one of declared Enum instance names

Can someone help me?
Thank you.
There is a server side change (Addition of a new Enum value) which is causing this devkit break. A newer version of devkit with latest changes (XSD) will be released soon. That will resolve the issue.
As a temporary workaround, you can try to call this without using devkit. Sample V3 call (using dev-defined) - https://gist.github.com/IntuitDeveloperRelations/0913b4c224de758fde0a
Update
This change might get rollbacked from the server side soon. In that case, current devkit will work as it is.

Reconcile Error: Has anyone had problems with truncated error messages?

I'm here again to ask for a help to you. This time I believe that few will respond given the great particularity of the problem which I will relate. I'm starting in the world of DataSnap, and still have things I do not understand how this error I will relate.
My Delphi is XE (version 1, Update1). I am using Postgres which generates error messages in Portuguese (Portuguese Brazil) and for this reason the error messages have accents. The connection components are ZeosLib package.
I am using a dialog box "reconcile error" to display errors arising from the application of updates and to test, I tried to insert a record that already existed, thus violating a unique key and thus displaying the reconcile error dialog.
In the memo of the dialog, the message that appears is truncated, ie cut. Check it out:
ERRO: duplicar valor da chave viola a restrição de unicidade "uc_usu_va_login"
DETAIL: Chave (va_login)=(admin) já existe.
CONTEXT: comando SQL "INSERT INTO USUARIOS (VA_NOME
,VA_LOGIN
,CH
But actually what should be returned is this:
ERRO: duplicar valor da chave viola a restrição de unicidade "uc_usu_va_login"
DETAIL: Chave (va_login)=(admin) já existe.
CONTEXT: comando SQL "INSERT INTO USUARIOS (VA_NOME
,VA_LOGIN
,CH_SENHA
,VA_EMAIL)
VALUES (pVA_NOME
,pVA_LOGIN
,pCH_SENHA
,pVA_EMAIL)"
PL/pgSQL function "idu_usuarios" line 7 at comando SQL
I have done a debug on the server to see if the problem is ZeosLib, but I found that the error message generated on the server is complete, proving that ZeosLib does not truncate the message. Everything is unicode. All strings are WideString (the default) on both my program and in ZeosLib.
As you know, to be thrown on the server, the exception is forwarded to the client, roughly speaking, by DataSnap, and on the client, the Reconcile method of TClientDataSet verify if there were problems and then throw the famous exception EReconcileError that can be handled in the OnReconcileError event of TClientDataSet, therefore I believe that the message is being truncated by DataSnap.
On the client I debug the Reconcile method (DBClient.pas) and immediately before the exception is thrown the flow enters a function within a cpp source code that I think part of the library midas.dll, MidasLib.obj more specifically, since I am using this strategy, not to have to distribute the DLL with my application.
Check(FDSBase.Reconcile_MD(FReconcileDataSet.FDSBase, FDeltaPacket, VarToDataPacket(Results), Integer(Self), RCB));
This call is done at line 1952 of the unit DBClient.pas on Delphi XE Update1. Pressing F7, the debugger enters a source C++ (cpp), so I believe it is within the midaslib.obj. How I do not understand C++ well, I press Shift-F8 to exit the current method and return the next instruction, that is already inside the event OnReconcileError!! Therefore, the truncation must be done within the function I mentioned, within a cpp source, within midaslib.
My intention is to make the Reconcile Error dialog a tool not only for the final user but to support personals, providing separately information of Error, Details and Context. This helps a lot to discover a problem.
The problem now is to make the message appear in full. Has anyone had this kind of problem with messages being truncated by midas?
Also another point DSClient.pas I could extract the error message as it is passed to the exception:
'Erro SQL: ERRO: duplicar valor da chave viola a restrição de unicidade "uc_usu_va_login"'#$A'DETAIL: Chave (va_login)=(admin) já existe.'#$A'CONTEXT: comando SQL "INSERT INTO USUARIOS (VA_NOME'#$A' ,VA_LOGIN'#$A' ,CH'
If you remove the quotes and replace #$A (1 character) by a white space (one character), you will see that the string has exactly 255 characters!!
I also discovered that the "GetErrorString" in dspickle.cpp uses the constant DBIMAXMSGLEN which is defined in bdetypes.h as 127 (half of 255). As we are in the world of Unicode, it would not be a question of increasing this value to 255 in order to have two bytes per character? This is only a guess...
I leave the question in the air because I lack the knowledge to understand C++ :) Who can help, just look at the function implementation "GetErrorString" in dspickle.cpp. There is this:
LoadString((HINSTANCE)hDll, iErrCode, pString, DBIMAXMSGLEN)
pString is the error message and DBIMAXMSGLEN = 127.
Contradicting the opinion of others I decided to tweak further and finally figured out how to increase the number of characters in the "Reconcile" error message. As I thought the problem was in midas.dll, or more specifically the sources that make up the midas dll because the same set of sources can create MidasLib, which does not require a midas dll. To resolve I had to install the Delphi C++ personality to compile the midas.
After finding the line of the error, I discovered that there is even a request for repairs to the QC (http://qc.embarcadero.com/wc/qcmain.aspx?d=84960) which seems to have been ignored by the staff of Embarcadero, as that the "Resolution" as is "Deferred to Next Rel" (Deferred to Next Release) but the request is from 2010 and I'm using Delphi XE which in my opinion should have the solution but here I am correcting by myself ;)
The problem is inside the method "Clone" of the "DSBASE" class, inside source "ds.cpp" at line 2133 (Delphi XE, Update1). Below is the code block. The red line is the problematic line:
// Set the third field for the error string.
LdStrCpy((pCHAR)pFldDes->szName, szdsERRMESSAGE);
pFldDes->iFldType = fldZSTRING;
pFldDes->iUnits1 = 255; // Increased on request.. DBIMAXMSGLEN;
pFldDes++;
Note that it is very interesting the problem line. It has a constant value of 255, which limits the size of the error messages and a comment "Increased on request". Also note that next to the comment, there is a constant DBIMAXMSGLEN, which I had found and already suspected as being responsible for the problem, but as it was not being used I changed the value of DBIMAXMSGLEN but the error message always came without changes. It is worth mentioning that there is a semicolon (;) after DBIMAXMSGLEN which leads me to think that before (I do not know when) this line was one that was just after my fix:
pFldDes->iUnits1 = DBIMAXMSGLEN;
It's as if someone had deliberately set the field value to 255, removing the previous implementation that was really dynamic and seemingly more correct. After performing the replacement of the line I increased the value of DBIMAXMSGLEN to 1024. DBIMAXMSGLEN is declared "bdetypes.h" as a define. After correcting the line went like this:
#define DBIMAXMSGLEN 1024 // Max message len
After these two changes in "ds.cpp" and "bdetypes.h" I build, test, and the result was as expected: the error message was presented in full in the Reconcile dialog.
To the brave who want to try if they have seen this problem, you need the sources of MIDAS, which comes with Delphi from 2010 if I remember correctly. Good luck to all.
