JLink error on Table setText

[BrianKrieger]

I have a set of code that essentially clears the contents of a cell.
This works in asynchronous mode but not in Sync. I'm just stumped.
Everything is the same, basically a session is created, the current
model is retrieved, detects that it's a drawing then collects two tables
and clears contents on two rows.



I've narrowed it down, I think, to an empty cell. Cell 1 is empty. If
I start with cell 2 (which has contents), all is right. If I start with
cell 1, error. Again, error only occurs in synchronous mode, async
works fine.



Any by some remote chance run into an issue like this with tables or
point me in a "d'oh!" direction?



I attached the full class for funsies (as my Thermo prof would say).



Thanks!

It's possible that JLink contains a bug which cause inconsistent behavior
between Synchronous and Asynchronous modes - they are different libraries,
after all. The first Pro/Toolkit bug I ever identified existing only in
Windows synchronous DLL mode, not EXE mode.

Have you tried using a debugger against this code, by the way? Doing that
would might bring you identify problems you're not yet aware of.

If I understand this correctly, your code is failing when you try to clear
a cell that's already empty. I agree that you should report such a bug to
PTC once you confirm it. At the same time, could you work around this by
reading the cell content and clearing it only if it's not empty already?

Brian,
From your description a simple check to do nothing if the cell already is empty might by an easy workaround.
An empty cell might return a NULL object that is handled in async mode but not in sync mode.
