I'm trying to figure out what is going awry with my use of XSLF.
It doesn't seem to be a POI issue per se, but maybe some weird interaction
between libraries or calls?
I can't really figure out where to look.
The situation: I am providing a netbeans module for use within a commercial
software (STARCCM) that itself is implemented using netbeans.
When using POI to create a pptx with tables, the content is not be added
correctly. For testing, I am using a simple bit of common code (see below), but
the results depend on how I call it.
If I call the PoiTests. runTest() method from a SystemAction (eg, from a menu
or top component), the table gets generated with content (no issues). If,
however, I use dynamically compiled and loaded java (they call it NeoScript) to
call the code, the table gets generated but without any content. It gets even
weirder though. If I use dynamic code to simply open a top component that
embeds the original SystemAction, the table is generated but without content!.
It appears that involving the NeoScript mechanism anywhere in the calling chain
it somehow influences the behavior of POI (maybe xmlbeans?) and inhibits proper
filling of the table content.
I can unfortunately not simply avoid the dynamic code bits, since these are my
only entry point for interacting with STARCCM for batch processes. I've
contacted the vendor (cdadapco), but they couldn't provide any answers at the
moment.
Does anyone have any ideas or even guesses about what might be going on here?
What could be going on behind the scenes within POI that could even slightly
explain this behaviour? I naturally suspect xmlbeans, but for no reason other
than everything about it is a mystery to me.
Thanks in advance for any guesses, hints, suggestions, etc.
Maybe someone has experienced similar odd interactions with other software that
might help put me on the right path.
