XControl Display state reinitializes

[Ton Plomp]

Hello All,

I'm working on a X-control containing a class. The facade VI-shows a picture, looks really great.

But...

I'm dynamically registring for events, so I can choose for each xcontrol I can register for certain events.

Now what happens is that IF a dynamic event is triggered the Display State (with the class) is reinitialized to it's default value, meaning my picture disappears.

Does anyone else have seen this (It also happens when I don't use dynamic registring....)

I'm resisting the urge to post code, since it's bad documented and quite complex (a class in an xcontrol)...

PS One question I should put my internal data off the xcontrol in the display state control right?

Some code would help.. I'm not really sure if I know what you mean..

Is it the actual "Display State In" control that get's an unexpected value? Did you probe this in the facade VI?

I've been playing a bit with classes in XControls too and have seen some strange behaviour, but haven't been able to put the finger on the exact problem yet.. Need to play around a bit more with this..

Yep, that would be the way to go! And don't forget to notify LV of state/data changes through the action output.
