NimbostratusHI all,
I just resolve this problem for my tests, maybe some variations will be needed for each particular irule, but this is the general idea:
1.- Put the statement that assigns the variable value from the class, in a place were the value needs to be utilized.
Put the statement inside other event that will use that variable other than "when RULE_INIT"
2.- Save the Irule
3.-Run your test. Run the scenario that will force to re-read the variable (in the new place). This action will force to assign the new value to the variable when needed in the particular event, example in "when HTTP_REQUEST" or "when HTTP_REQUEST_DATA "
4.- The new value will be the F5 memory
5.- Remove the statement from that place and leave your irule as before.
6.- Save the irule
7.-Done
