Andrew Borley commented on TUSCANY-554:
---------------------------------------
I believe I hit this issue when dealing with DataObjects in the SCA binding.ws.
When axis returns from a ws call, the axiom node gets converted into a DO (call
it DO1), and then the value or DO (DO2) within is returned to the calling
component. So, when a DO is returned, DO2 is contained by DO1. Leaving the
binding.ws code means that DO1 falls out of scope and is destroyed, but this
destruction doesn't signal to DO2 that his container is no longer valid. So you
can do DO2->getContainer() and get a pointer that looks good, but fails when
you try to use it.
So the code is something like:
DataObjectPtr* do2 = new DataObjectPtr();
{
DataObjectPtr do1 = axiomHelper->tosdo(axiom_doc, datafactory);
*do2 = do1->getDataObject(0);
}
// do1 has fallen out of scope and is destroyed.
// However, this call returns a good pointer
DataObjectPtr container = do2->getContainer();
if(container)
{
// container is not 0, but this call causes a crash
container->getType();
}
Adding do2->detach() before do1 falls out of scope fixes this issue, but I
think the destruction of do1 could be made to call detach() on any data objects
that do1 contains
