BPM Problem: Data types are not compatible

[Former Member]

Hello,

i have a Business Process with a Container Operation.

i copy with an xpath expression one field in one container variable.

that works.

now i have a second Container Operation where i try to copy another field in one container variable.

It's the same... only other field in XPath expression and i got following error in xi_cache:

Returncode 99
Data types '' and 'SWFXST_STRING' are not compatible.

Any idea what going wrong here ?

why does one operation work and one not ?

Regards,

Robin

I am afraid of XI copy function. Sometimes it is giving weird results, delete the container operation and recreate it manually. Most of the times it works. If that does not solve, delete the container and create it with a new name.
