Can anybody suggest the way to force User Interaction dialogue to appear every time when its element is executing within a workflow?
There's a problem with usability, when same User Interaction element called from a loop shows up the dialogue window only the first time, and on next loop iterations user must either click an icon or select a menu item to bring interaction dialogue window up.
Do you mean in the vco client or in the vSphere web client ?
I cannot test this ATM but maybe starting a new workflow (nested or asynchronous) containing the user interaction would be a work-around.
I can confirm the behavior you describe for a loop.
Unfortunately asynchronous open an infinite number of user interactions but none on the screen and nested none on the screen.
I sppose that if there is a user interaction the loop is not infinite. You may be ble to do something like this:
