The old behaviour was that a dynamic property get called every time.
Now the set_<name>_internal function get's called instead of the
propery itself. This is done within the caller thread to prevent
a lock if the task is scheduled external.
If the task is already configured then the user setter function get's
called WModified handling of dynamic-properties:
The old behavior was that a dynamic property get called every time.
Now the set_<name>_internal function get's called instead of the
propery itself. This is done within the caller thread to prevent
a lock if the task is scheduled external.
If the task is already configured then the user setter function get's
Called WITHIN the user thread (which means the scheduler must run).
The user has to make sure that ALL dynamic properties get's read within the
Configure hook. The setter function does NOT get called if the task is so far
unconfigured.
ITHING the user thread (which means the sceduler must run).
The user has to make sure that ALL dynamic properties get's read within the
configure hook. The setter function does NOT get called if the task is so far
