I have a simple cached submission with xxf:cache="true" and xxf:readonly="true". If I trigger this submission with xf:send then it will be executed only once (as expected). But from time to time the returned data of the submission changes.
Is there a possibility to rerun this cached submission?
You can invalidate the cached document by dispatching xxforms-instance-invalidate to the instance. More on this in section linked below. Would this work for you?
