transaction context - and certainly DONT allocate/remove inside other
transaction event processing.
Explanation: So there are some instances where you cant (or should
not) do certain things inside events - since that would violate the
status of loops etc when the processing returns to the outer call.
I hope that makes sense, its a bit hard to explain without lots of
code for demo.
While I have not investigated I would expect that this is what you
are encountering. You need to find a way to perform your query
allocation/deletion outside of IBO transaction event processing.
