By using g:datePicker on java.sql.Time object that refers to a TIME legacy DB column I get this error:
Failed to convert property value of type java.util.GregorianCalendar to required type java.sql.Time for property jobTime; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [java.util.GregorianCalendar] to required type [java.sql.Time] for property jobTime: PropertyEditor [org.codehaus.groovy.grails.web.binding.StructuredDateEditor] returned inappropriate value
I've searched through the whole web for hours but can't still figure out how to do, is there someone who can help please?
It looks like you're trying to convert a GregorianCalendar object to a Time object (at least, that's what the object says its doing). Try manually doing it:
// assuming that 'jobTime' is the object you're dealing with
jobTime = new java.sql.Time(jobTime.getTimeInMillis())
If you're absolutely sure its a Time object, try converting it to a Date object.
jobTime = new Date(jobTime.getTime())

I'm trying to create a MutableProperty which holds a Results received from Realm.objects(_:).
To create the property I need to give it an initial value; hence an 'empty' Results.
I've tried creating one using:
var someThings = Results<SomeObject>()
MutableProperty(someThings)
But the compiler gives me the error: Cannot invoke initializer for type 'Results<SomeObject>' with no arguments.
While I understand the error, I'm not really sure how to create a Results object in this context.
Looking at the source of Results I couldn't find an init either.
So my question is; how can I create a Results myself to use in a MutableProperty?
Edit:
I've seen this question...but that doesn't really help (unless I'm going to create a "wrapper" for the MutableProperty or something).
With help of the comments on my OP; I created a mutable property with an empty set of results by fetching objects with an 'invalid' filter.
E.g. MutableProperty(realm.objects(SomeObject.self).filer("EMPTY SET")).
I'm trying to give some DateTime fields default values from the model browser.
Whatever I type into the Default Value field, I get an error telling me The value must be in the form 'yyyy-MM-dd HH:mm:ss.fffZ'. I am assuming that format string uses the scheme documented here.
The value I punched in is 2014-05-23 00:00:00.0000, which I believe is of that form. I'm not sure whether 0 is a valid value for the Z component, but I don't know what the right value would be.
What could be wrong with the string I gave?
I figured it out. The Z component was indeed the issue. I just needed to use 2014-05-23 00:00:00.000Z instead.
I am trying to pull in a RSS feed and sort by pubDate. When I examine the 'updated' property, most of the time it is correct and give me a proper date but when I try to convert from a set to a sorted array, I get random results from the sort. I've tracked this down to the fact that when sort is doing it's comparesion, the property (which is an NSDate, see figure1) is coming in and being compared as a __nscfnumber! (also figure2)
Any help or idea would be much appreciated.

I assume the comparator block is just for diagnostic purposes? You don't actually need to supply a comparator for NSDate or any of the provided attribute type classes.
If the debugger is reporting that the date1 object is of a NSNumber-cluster class type, then somewhere a NSCFNumber instance is being assigned to to the updated attribute. The debugger ignores factors like a cast and instead simply asked the object what its class is. If the object says it is a NSCFNumber then it is, regardless of how the code treats it otherwise.
Why that happens, I can't say based on the code provided.
You might try logging the value and class of the updated attribute before you attempt the sort to see if it reports properly. I would also recommend decomposing the entire line. Nesting all those method calls will work of course but it is error prone and hard to debug.
I'm encountering the following problem - I have simple GWT overlay types, and I'm trying to convert one to a JSON string on the client; I'm simply doing:
new JSONObject(this).toString();
The conversion works, but it adds an additional, incorrect key to the json string, such as:
{"key1":"value1", "key2":value2, "$H":1}
where "$H":1 doesn't correspond to anything in my overlay type.
Any idea why this is?
Any help is appreciated on this, thanks.
This issue is define in this link
The $H property comes from the
implementation of
JavaScriptObject#hashCode() (in
com.google.gwt.cire.client.impl.Impl#getHashCode(Object)).
In your case, this is due to
AbstractEditableCell maintaining a map
of value keys to their "view data",
and your use (I guess) of the default
ProvidesKey implementation
(SimpleProvidesKey) which directly
returns the item.
So, when rendering, the EditTextCell
calls getViewData, which looks up the
key in the map (and thus needs the
hashcode of the key, hence the call to
hashCode), and the key is your JSO
(hence the new $H property).
I believe that giving a ProvidesKey
implementation (in you case, returning
the name property for instance) to the
Celltable would solve your issue.
Using Struts 2.1.6, xwork 2.1.2 and ognl 2.6.11
In my struts action I have a Map that I am fetching elements from using OGNL. If the key I am using to fetch with does not exist in the map then OGNL returns an empty object array, that OGNL converts to a string and I get the object reference java.lang.Object#6.... This occurs in several places and seems to be the the map having the value generic specified as an Object. This is not something I can change.
I have traced the problem for a while, but when I ended up deep into the guts of the OGNL code and I did not see a light at the end of the tunnel. Currently I am going to go with an ugly hack of checking the string return to see if it starts with "java.lang.Object#" and if so return an empty string. I don't like the solution but thats what time permits.
Has anyone encountered a similar problem?
Also, where did OpenSymphony go? updates to their webiste appear to have dried up, the user forums say they are being converted to Google Groups no later than Nov-12-09
This is a problem with null values: if value is null, default behavior is to create a value using default constructor. Since the value type of your map is Object, new Objects are created where null is.
In order to stop this behavior:
use #CreateIfNull( value = false )
use mapName_CreateIfNull=false in classname-convertion.properties file.
