gwt.xml

Let me add the gwt.xml, too. The forum only allows 5 attachments per post.

There are a few legacy comments there since it is copied from another project, but it makes the test case complete.

Forgot: The problem occurs in the LGPL version

Your use of a GwtRpcDataSource as well as leaving in place a bunch of unrelated code makes this a pointlessly overcomplicated test case and introduces the possibility that the flaw is actually somewhere in your DataSource implementation or other extra code.

If you hope to see this report looked at quickly, follow the rules and make your test minimal: use an actual clientOnly DataSource and delete the extra code. The whole thing should fit neatly into one .java file and not require any setup beyond dropping it into one of the sample projects - that's what's meant by a test case.

Damn, just noticed I f**d up the copy & paste so plz ignore the code above

Bad day

In the previous post I still extended the wrong datasource, even though that only needed to be changed to DataSource.

Anyway, here is the simplified, one class, hopefully now unpointless test case.

The gwt.xml now refers to a different EntryPoint, but I guess that is not a problem, since that file wasn't necessary anyway, as I learnt now.

Code:

Thanks for the simplified test case, that helps a lot in terms of pinning down the bug.

This is fixed for affected builds - grab the next nightly for the fix.

**SCAI_Andre** · 14 Jan 2015, 04:24

tested nightly 5.0p/LGPL/2015-01-14:
can confirm it is fixed

Thank you!
