[nebula-dev] Refresh Gantt

[Víctor Cima Granda <victorcg.nortia@xxxxxxxxx>]

Hi!. I have a Gantt in my app that show a lot of campains that can be 
filtered using a search. My problem is that the first time the Gantt 
works fine, but when i do the search the campains, Gantt doesn´t change 
and show me the same campaigns than before the search.

I have two frames one with the GanttControlParent (show the tree with 
the name of campaigns, state)  and other SashForm (show the graphic)

Regards
