Substitution Strings Update without Page Submission

Question

I have a Dynamic Action D1 with a custom attribute C1. C1 is a text field that uses substitution string referring the page item P_ITEM as &P_ITEM. But the &P_ITEM. is only substituted during rendering of page.

I also have a dynamic action D2 which updates the P_ITEM in session state. If I try to run the action D1 which uses &P_ITEM., instead of using the new value in session state, it still uses the old value during the time of page rendering. In this scenario, I can only run D1 as expected if I submit the page. Now, the question is, how do I update &P_ITEM. without page submission? Is it even possible? I know that there is Page items to submit option if it were a SQL Source which uses bind variable :P_ITEM. BUT this is specifically using substitution string as &P_ITEM.

One of the solution might be to re-render the dynamic action without rendering the page. It is just the idea I have and I don't know if this can be done or not.

Answer 1

The reason you might use substitution strings (e.g. &P_ITEM.) is because you don't want them to react to session state changes on the client.

If you want the value of the state of the item on the client, use javascript $v("P_ITEM"), or if you're running a PL/SQL dynamic action, pass it as a bind variable :P_ITEM.
