When some buttons are clicked they will change the state of the system, but other UI components will not detect that change correctly. So those triggers are put on hold. This will fetch hold status for a specified inputId
Arguments
- state
module state with all of the current ui elements populated
- inputId
The input ID of the UI element that was put on hold
Examples
# Within shiny both session and input variables will exist,
# this creates examples here for testing purposes:
sess_res = DW_test_mksession(session=list())
