Problem
---------
In my java code, I have the following
oC = (Control) XWT.load(parent, url, loadModel("SG.xml"));
System.out.println ( XWT.getDataContext(oC)) ;
I would like to refresh the TableViewer with the contents of SGNew.xml in
the runtime.
Since I didn't see setDataContext such as
XWT.setDataContext(oC,loadModel("SGNew.xml")),
I tried setting the input of TableViewer with the result of
loadModel("SGNew.xml"), obviously it threw the following error
"org.eclipse.core.runtime.AssertionFailedException: assertion failed: This
content provider only works with input of type IObservableList"
What is the best way to proceed ?
Thanks,
Best Regards,
Walter G. Prabhakar.

The error message states that you are using the wrong data provider.
There is a xml data provider (..e4.xwt.xml) to be used for xml data.
Though, I am not sure how mature the data provider is.
In your binding declaration you will have to use xpath expressions, e.g.:
{Binding path=//users/@name}
Afaik, you can only set the data context once, prior to loading the UI.

You can always to get the file content, create a IObservableList to pass and
then pass it to TableViewer. But you need to know data binding framework.

The simple way is just to reload the XWT resource to recreate UI with new
data context.

By now, It is a POC. We need to develop more tests. Particuliarly, the xpath
expression may have a problem with some special characters.
