B4J Question BBScrollingLabel customview crash

It happens because of the unneeded Sleep call.

You must set the text engine right after the layout is loaded. You should also set the text (this is something that should be fixed in the library, it should have handled empty text).

Thanks, found it. (the sleep addition was trying to find a solution but seems not the problem..)

If there's no text assingment in BBScrollingLabel2 in AppStart , the app crash

Waiting for debugger to connect...
Program started.

The solution is assign a text in AppStart (I thought that this was ammended).
A bit strange that it should have a text assingment in AppStart (tried to assign a "" or " " but didn't work); I'll have to play with View's visibility for not displaying initial text (but this property doesn't exist on BBScrollingLabel view, and must create a Parent panel to hide the view)

Adding this to the b4xlib code does the job
