Description Winston Prakash 2008-02-21 17:47:13 UTC

This is reported by customer.

When a project contains several Managed beans and several pages, the page comes
up quickly (15-20secs). But after that until the outline is refreshed, the whole
IDE freezes. No indication (no wait cursor), to say what is going on. Probably,
outline could use some asynchronous ChilderenFactory utility to avoid IDE freeze,
when insync models all the Managed Beans. Attaching a project that depicts the 
problem.

Investigating.

Comment 3 Peter Zavadsky 2008-02-21 19:51:12 UTC

So it seems that the method FacesDesignProject.findDesignContexts(String[]) is the one causing the problems. However
this methods blocks the AWT, and it seems it is possible to be called from AWT thread only.
I think insync needs to provide loading mechanism similar to when loading the FacesModel to solve this, i.e. that the
loading could happen in the non-AWT thread. Then the outline children could use the mechanism.

Changing this to an enhancement. It turns out user do not have that many 
Session Beans. We do not model all the page beans. So for now, this should
be OK
