Error 1003 on second and subsequent opens of VIT

[BillMe]

I have a VIT called dynamically (a graph) that works fine in development mode. When my app is built however, only the very first call to open the graph is successful, second and subsequent calls fail with Error 1003. None of the VIs in my app are broken. The VIT properties are set for REENTRANT and PREALLOCATE (send in the clones) using LabVIEW 8.5.

I should also mention that the VIT was built as part of my .exe, I'm not loading it off disk.

For starting any VI dynamically it is important that the started VI has opened a reference to itself, before the Caller closes the reference.

The called VI will have an open reference when the FP is open.

The fact that it works in dev mode and not in exe, could indiacte a timing problem.

I found the following document very usefull in VI template dispatching.

I found the problem. If the VIT is in a .lvlib, you can't open more than one instance. Now to find out why.

Strang, but good to know when I convert my code to LV 8.x.
