Re: [nebula-dev] GridViewer add filter hangs

[Tom Schindl <listom@xxxxxxxxxxxxxxx>]

Hi,

We inherit this behaviour directly from JFace-Viewer so the only chance
to get this fixed is up-stream in JFace without a fix in JFace the only
possible solution is to filter outside the viewer and set a new input
afterwards.

I'm working on a new incarnation of JFace-Viewers for E4 which should
address async-stuff and much more in
https://bugs.eclipse.org/bugs/show_bug.cgi?id=260451
