Comment 3 Ondrej Vrabec 2015-11-01 16:05:50 UTC

Martine, could you switch TemplatesAction to run in EDT? It does a lot of swing stuff but runs in a RP.

Comment 4 Martin Entlicher 2015-11-01 18:21:23 UTC

Agreed, the Swing code must run in EDT.
This action seems to be asynchronous by a mistake.

Comment 5 Martin Entlicher 2015-11-02 10:51:51 UTC

The action is unusable => P2 at least.

Comment 6 Martin Entlicher 2015-11-02 11:01:55 UTC

Integrated into 'main-silver', will be available in build *201511030002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Changeset: http://hg.netbeans.org/main-silver/rev/462935f9d0ef
User: mentlicher@netbeans.org
Log: #256289: Make the Templates action synchronous, since it's initializing a lot of GUI.
