Hello there,
I have a problem with XWT databinding. I got my XWT table and a list as an input. I got my columns displayed but it wont show me content. The Eclipse console says:
!ENTRY org.eclipse.core.databinding 2 0 2014-06-25 11:39:22.228
!MESSAGE elementType cannot be null

What can I do to fix this?

My classes :

<Composite xmlns="http://www.eclipse.org/xwt/presentation" xmlns:x="http://www.eclipse.org/xwt" x:Class="de.datec.kassenbuch.ui.xwt.DetailPartXwt" xmlns:p1="clr-namespace:org.eclipse.jface.viewers"
xmlns:p2="clr-namespace:de.datec.kassenbuch.ui.table">
<Composite.layout>
<FillLayout/>
</Composite.layout>
<TableViewer x:Style="BORDER | FULL_SELECTION" input="{Binding path=buchungen}">
<TableViewer.table headerVisible="true" linesVisible="true"/>
<TableViewer.columns headerVisible="true">
<TableViewerColumn width="50" text="ID" bindingPath="id">
<TableViewerColumn.labelProvider>
<p2:IdColumnLabelProvider/>
</TableViewerColumn.labelProvider>
</TableViewerColumn>
<TableViewerColumn width="440" text="Datum" bindingPath="datum">
<TableViewerColumn.labelProvider>
<p2:DateColumnLabelProvider/>
</TableViewerColumn.labelProvider>
</TableViewerColumn>
<TableViewerColumn width="440" text="Betrag" bindingPath="betrag">
<TableViewerColumn.labelProvider>
<p2:AmountColumnLabelProvider/>
</TableViewerColumn.labelProvider>
</TableViewerColumn>
<TableViewerColumn width="400" text="Einnahme / Ausgabe" bindingPath="ausgabe">
<TableViewerColumn.labelProvider>
<p2:TakeGiveColumnLabelProvider/>
</TableViewerColumn.labelProvider>
</TableViewerColumn>
</TableViewer.columns>
</TableViewer>
</Composite>

public DetailPartXwt(Composite parent, int style, Object object) {
super(parent, style);
setLayout(new FillLayout());
// load XWT
String name = DetailPartXwt.class.getSimpleName()
+ IConstants.XWT_EXTENSION_SUFFIX;
try {

URL url = DetailPartXwt.class.getResource(name);
Map<String, Object> options = new HashMap<String, Object>();

TableModel model = new TableModel();
options.put(IXWTLoader.DATACONTEXT_PROPERTY, model);
options.put(IXWTLoader.CLASS_PROPERTY, this);
options.put(IXWTLoader.CONTAINER_PROPERTY, this);
XWT.setLoadingContext(new DefaultLoadingContext(this.getClass()
.getClassLoader()));
XWT.loadWithOptions(url, options);

} catch (Throwable e) {
throw new Error("Unable to load " + name, e);
}
}

public class TableModel {

@Inject IDataService dataService;

List<KassenBuchungReduced> buchungen = new ArrayList<KassenBuchungReduced>(); {
KassenBuchungReduced test = new KassenBuchungReduced(1, new Date(120,2,2), 350, false);
}

public List<KassenBuchungReduced> getBuchungen() {
return buchungen;
}

public void setBuchungen(List<KassenBuchungReduced> buchungen) {
this.buchungen = buchungen;
}
}

Unfortunately, that is just the internal exception message thrown by the databinding framework.
Instead of this (or additionally):

throw new Error("Unable to load " + name, e);

Do the following and provide the output of it (that is the stack trace):

e.printStackTrace()

The problem is that there is no difference.
I don't get any output from

e.printStackTrace()

Edit: I just get the same message I posted before.

Maybe, you could extract a standalone sample that reproduces the error message?
And did you check your POJO KassenBuchungReduced? Mabye, it returns null in one of its getters?

Hey there,
it was all my fault. I don't know how but I got the wrong Databinding Plugin(wrong Version). I deleted it from my plugin.xml and everything was fine.

Oh yes and my TableModel class had a typo.. shame on me...

Much love for XWT!

Hello,

now I got a new problem. I've read http://erdalkaracade.blogspot.de/2013/07/eclipse-e4-emf-and-xwt-in-action.htmland I want to export the selection from my table I made with xwt and use it in another part, just like you did.

When I use

<Composite.Resources>
		<Var x:Name="booking" varName="selectedBuchung"/>
	</Composite.Resources>

I get the following error :

Has the name changed? Or the whole way to do this?

When I do the e4 Inject/Optional/Named("selectedBuchung") thing, the object i get is null.

@Inject @Optional @Named("selectedBuchung")
	private Object modelElement;

Hi Sascha,
The E4 integration using the Var/Export mechanism was a proposal.
Up to now, no feedback from the community, so it did not make into the final release.

You can check out the sources into your workspace and build it yourself, for now:

git: http://git.eclipse.org/c/xwt/org.eclipse.xwt.git/tree/org.eclipse.xwt.e4

If you want this feature to be integrated into XWT itself, please file a new enhancement request.
And please do not hijack existing forum posts for different issues Smile

Has the name changed? Or the whole way to do this?

When I do the e4 Inject/Optional/Named("selectedBuchung") thing, the object i get is null.
@Inject @Optional @Named("selectedBuchung")
	private Object modelElement;

Hi Erdal,

thanks again for your help!
I'm learning Java/Eclipse since 3 months and I think XWT would make UI development so much faster. The problem is I don't know how to implement this feature myself but I got a different solution. Enhancement request this evening.

Greetings Sascha
