I tried doing this in treeview drag drop and to my sad surprise, yes,
it doesn't work! A little bit of investigation showed that all
JSignal's were affected: they would not get propagated properly. Since
many Ext events are propagated using JSignals, that explains the ExtJs
problem. The following patch solves it:
src/web/skeleton/Wt.js, line 1161, change:
if (responsePending == null)
scheduleUpdate();
to:
scheduleUpdate();
I am going to push this fix soon to the public git branch, together
with other fixes...

It doesn't matter -- in fact, you can also freely enabled and disable them.

There is no nicer compliment a programmer can get ! :-)
