small bugfix

Hi everyone,

I noticed that changed after "edit node properties" were not displayed. 
They were only shown after changing from gant to pert. I have added a 
call to slotUpdate after openDialog in order to display the changes.

On my computer kplato crashes quite frequently during startup. Does that 
happen to anyone else too? So far I have not found out the cause, but I 
will keep looking.
These crashes also occured months ago, when I first tried kplato. In 
both cases (then and now) it was KDE 3 built from cvs, so in both cases 
KDE was up to date.

I also noticed that the dialogs after "edit node property" have some 
problems. For a task dialog, the task name and the responsability get 
copied from the object to the dialog. However in the subproject dialog I 
get empty fields. Is this just an incomplete implementation?

So much for today,

Heiko Evermann
