It is RexxActivation::termination() that will issue a contextObject->detach() which nullifies the
activation vairable such that RexxContext::checkValid() will raise the execution error.

Could get the invocation id into the stackframe and callerstackframe.
As your .context idea is quite intriguing :) I then attempted to add it to the StackFrameClass
using RexxActivation::getContextObject() which at first sight seemed to work as well. However when
fetching it from a stackframe and trying to interact with it the runtime error "Execution error.
Target RexxContext is no longer active." occurs.
The RexxContext methods will issue a checkValid() before proceeding, which is
defined as:
void RexxContext::checkValid()
{
if (activation == OREF_NULL)
{
reportException(Error_Execution_context_not_active);
}
}
It seems that the backing RexxActivation gets nullified such that placing it into a StackFrame is
of no use ATM.

First of all, RexxActivaion is an RexxInternalObject. Those must NEVER be returned as an instance
by Rexx code. They are not fully functional objects that can be seen by Rexx code. There are also
issues with NativeActivation which is part of the same hierarchy with RexxActivation and also
must never be returned to Rexx code. If you really feed the need to do this, a better choice
would be to return the .Context object associated with the activation. Buy you need to make this
adjustment in every place an StackFrame object is created, because only RexxActivation ones will
have a backing context.

Currently, the stackframes do not contain the information to which
RexxActivation
(“invocation”) they relate to. As a result, a caller stack frame cannot be
consulted to learn
which invocation created the called invocation. This is vital information
in case one creates
a tracelog and wishes to analyze exactly the flow of control post-mortem
using a tracelog.
Therefore, I would like to add that information to stackframes using the
name “invocation”
storing the value of RexxActivation::getIdntfr() and adjust
RexxActivation::createStackFrame() and the StackFrameClass accordingly.
Would there be
something else that one needs to pay attention to?
