Why if you do a "before group" trigger if you change any of the parameters used within the group's session that they aren't changed when the session runs? Is the parameter's data cached as soon as the group is loaded so those parameters can't be updated within a "before group"?
Hi Micah,
You are on the right thinking path regarding what is happening, in the case of groups with an HTTP session, the parameters are built into a request when placing the group on the execution queue (not yet executing but to be executed).
The "before group" trigger will set off right before the group is set to execute so at that point the parameters are already "locked in" and cannot be modified for that session.
