Moin!

I get the following error using CellList in GWT 2.3 in this piece of code:

TestG.java:91:  CellList<String> cellList = new CellList<String>(new 
ClickableTextCell());

the Error:

'com.google.gwt.resources.rebind.context.InlineClientBundleGenerator' threw 
an exception while rebinding

I searched for this error and came across various posts, that basically said 
to increase ulimits open files parameters. However that didn't fix the 
issue. Anybody care to tell me, where to look for the bug?

Kind regards, Mark
