I am trying to piece together posts about config code for non-EF apps. It seems I need to:
core.config.initializeAdapterInstances(
new DataService({
serviceName: serviceName,
hasServerMetadata: false
}));
So, although very silly, I cannot seem to find core.config.initializeAdapterInstances. How do I get this stuff to resolve??
thanks

If the problem is that core is undefined, then try to add this line before your code
var core = breeze.core;

I occure a problem which I do not understand. Following code does not work:
AccountingEntity accountingEntity = AccountingEntity.get(params.id);
accountingEntity.setLifecycleStatusToArchived();
accountingEntity.save(flush:true);
Where the method setLivecylceStatusToArchived looks like:
void setLifecycleStatusToArchived() {
this.lifecycleStatus = AccountingEntity.LIFECYCLE_ARCHIVED; //predefined static variable
this.considerForRankingJob = false;
this.dateArchived = new Date();
}
Problem is, that the entity is not updated.
No validation erros when I use accountingEntity.validate() in advance.
However, this code works:
AccountingEntity accountingEntity = AccountingEntity.get(params.id);
accountingEntity.setDateArchived(new Date());
accountingEntity.setConsiderForRankingJob(false);
accountingEntity.setLifecycleStatus(AccountingEntity.LIFECYCLE_ARCHIVED);
accountingEntity.save(flush:true);
The code did not work any more after update from Grails 3.2.9 to 3.3.0.RC1 (Gorm 6.1.5) unless I followed all the steps in the guide (http://docs.grails.org/3.3.x/guide/upgrading.html) and the rest of the code is working properly (also database accesses etc.)
Has anybody an idea? What the problem could be?
Thanks in advance and best regards!
The short answer is dirty checking. When you are setting properties inside the instance method Grails doesn't know they are dirty.
See the following github issue for how to resolve the problem:
https://github.com/grails/grails-data-mapping/issues/961
you have 2 options:
call markDirty every time you change an internal field. This will be
better for performance or as per
http://gorm.grails.org/latest/hibernate/manual/index.html#upgradeNotes
use
hibernateDirtyChecking: true
I try to get the service metadata of a sapui5 v2 odata model.
Code:
var oModel = new sap.ui.model.odata.v2.ODataModel(someServiceURL);
var oMetadata = oModel.getServiceMetadata();
This should work according to this page:
https://openui5beta.hana.ondemand.com/docs/guide/6c47b2b39db9404582994070ec3d57a2.html
Anyhow I got "undefined" for oMetadata.
If I change code to:
var oModel = new sap.ui.model.odata.v2.ODataModel({
loadMetadataAsync : false,
serviceUrl : someServiceURL
});
Still oMetadata === undefined
According to SDK documentation metadata should be loaded in sync:
Return the metadata object. Please note that when using the model with
bLoadMetadataAsync = true then this function might return undefined
because the metadata has not been loaded yet. In this case attach to
the metadataLoaded event to get notified when the metadata is
available and then call this function.
What is wrong with my code?
I am using (1.28.11):
<script src="https://sapui5.netweaver.ondemand.com/resources/sap-ui-core.js" ...
I started debugging the UI5 code and detected following line:
this.bLoadMetadataAsync = true;
I started debugging of SAPUI5 code and detected following line (seems to be called each time):
this.bLoadMetadataAsync = true;
Is it a bug? Or is something wrong with my code?
Solution:
The following worked for me in an actual application environment. I guess it not being fired in my fiddle was due to no actual data request being made:
var oModel = new sap.ui.model.odata.v2.ODataModel(<ServiceURL>);
oModel.attachMetadataLoaded(null, function(){
var oMetadata = oModel.getServiceMetadata();
console.log(oMetadata);
},null);
Lead up to the solution:
Ok so I started playing around with this a bit and found the following:
.getServiceMetadata() worked fine with sap.ui.model.odata.ODataModel.
with the sap.ui.model.odata.v2.ODataModel the request for the metadata was sent through the network but somehow .getServiceMetadata() returned undefined.
I tried to sap.ui.model.odata.v2.ODataModel.attachMetadataLoaded() but the event was never fired. (This only applied in the jsbin I used)
I will edit this with any further findings I make. If you have anything that should be included in my findings/testing just tell me.
Edit:
The bLoadMetadataAsync is a parameter you can set on the sap.ui.model.odata.ODataModel. The parameter is not in the API for sap.ui.model.odata.v2.ODataModel anymore. I assume that the async loading has been choosen as default.
Edit:
#user3783327 Reported a bug here: https://github.com/SAP/openui5/issues/564
As sirion already mentioned, the ODataModel has now an API named metadataLoaded which returns a promise accordingly. In the resolve function, we can definitely get the service metadata via getServiceMetadata().
myODataModel.metadataLoaded()
.then(() =>/* Do something with */myODataModel.getServiceMetadata());
Alternatively, we can also make use of ODataMetaModel which can be set on any ManagedObject (including View) and provides several useful accessors related to the service metadata. In order to get the meta model, we need to use the appropriate API from the ODataModel instead of instantiating the model directly:
myODataModel.getMetaModel().loaded()
.then(() =>/* Do something with */myODataModel.getMetaModel()/*...*/);

How can I print a map from the OpenLayers? I want to add print button in my OpenLayers page =) I have MapFish extension for my geoserver, but don`t know how to make request to it. Any other ideas are welcome) Help please.
I had a similar problem using a reverse proxy, because I discovered the answer from info.json contais local ip reference instead of the public url
to solve brutally i replaced the ip referenze with the public url in the ajax request (see the following code. I hope it can be usefull for others...
this.capabilities.createURL = this.capabilities.createURL.replaceAll("192.168.0.0:8080", "mypublicurl");
this.capabilities.printURL= this.capabilities.printURL.replaceAll("192.168.0.0:8080", "mypublicurl");
Ext.Ajax.request({
url:this.capabilities.createURL,
jsonData:jsonData,
success:function(response){
response.responseText = response.responseText.replaceAll("192.168.0.0:8080", "mypublicurl");
window.open(Ext.decode(response.responseText).getURL);
}
});
The simplest way is to use GeoExt.PrintMapPanel (geoext example). And be sure to read GeoServer Printing Module.
UPD GET request example. You must modify url, "baseURL", "layers". If you specify an existing layer, this request must return pdf file.

What is the difference between:
Msxml2.DOMDocument
Msxml2.XMLHTTP
? And of course, the other question is which one will work best for my purpose as described below?
The context is this - I have code that makes many calls to retrieve web pages. I am looking for the most efficient object for this task. For example, something like this:
Dim oXmlHttp : Set oXmlHttp = CreateObject("MSXML2.XMLHTTP")
oXmlHttp.Open "GET", sUri, False
oXmlHttp.Send
If Err Then
getWebPage = "ERROR - could not get the source text of the webpage."
Exit Function
End If
sResponse = oXmlHttp.responseBody
This seems to work the same way if I create an object using:
Dim oXmlHttp : Set oXmlHttp = CreateObject("MSXML2.XMLHTTP")
Can anyone explain or point me to a reference that clearly outlines the differences (and intended usages) for each of those?
If you want to learn more about MSXML, these links may help:
http://msdn.microsoft.com/en-us/library/aa468547.aspx
http://msdn.microsoft.com/en-us/library/windows/desktop/ms766487(v=vs.85).aspx
In short, XMLHTTP is used to retrieve information, while DOMDocument is used to structure and parse it.
This page explains it better: http://msdn.microsoft.com/en-us/library/windows/desktop/ms760218(v=vs.85).aspx
DOMDocument "Represents the top node of the XML DOM tree." while XMLHTTP "Provides client-side protocol support for communication with HTTP servers."
I am trying to set up an event stream using MVC.NET, Nginx and Fastcgi. The streaming works fine for me using xsp4, but I have not been able to get it to work through Nginx and Fastcgi. My goal is to open an EventSource stream and to downstream data to my website.
I have tried adding the 'ngx_http_upstream_keepalive' module - http://wiki.nginx.org/HttpUpstreamKeepaliveModule - which is funny because there is "Note - this This will not work with HTTP upstreams" in the module description. But wait, isn't that the name of the module? Anyways, maybe I'm confused here. I have also tried adding 'proxy_buffering off' to my nginx.conf, which also hasn't helped.
I understand this should be fairly easy to do, but I am at a loss. Is there some property I can add to my nginx.conf to make this work? Or is there something to add to the Response in .NET?
Please help me StackOverflow!
Based on what I have read here:
http://wiki.nginx.org/X-accel
you need to turn off X-Accel-Buffering. Here is some example code:
public ActionResult Stream(string id)
{
Response.ContentType = "text/event-stream";
Response.Buffer = false;
Response.BufferOutput = false;
Response.Headers["X-Accel-Buffering"] = "no";
return View();
}
Hopefully the code above fixes your problem.
