findNumRowsToPaint throws NullPointerException

[ikus060]

In reference to #46 , I'm experiencing this exception too with version 0.9.11.v7. While some user can reproduce it every time, others never saw it. Users having this issue, only enter a value in a filter and refresh the table: calling table.getContainerSource().refresh();

Hi ikus060, I opened ths pull request #77 that addresses this NPE.

Please have a look and see if this version of FilterTable addresses your issues.

Anything new about this? This one is hitting me seriously...

We are also affected by this bug, but were so far unable to reproduce it. Can anybody confirm that pull request #77 fixes the issue?
