I have created an active link that runs when a specific value is selected from a dropdown list by choosing an Execute Condition of Menu/Row/Level Choice.
The If Action is a Message with a Type of Error.
The Message displays perfectly well in the window (which is opened in New) when the value is selected from the dropdown but when I ok the Message the window remains open and does not close.

Hi,

if you raise an Error type of message, the execution is stopped. You either need to display the message before opening the window, or if you want to display the window, display another kind of message (Warning for example), and put a Close Window action afterwards.

Hmm, tried a close window action after the error message action and the original window with the dropdown still remains open.

Hi,

the error message stops execution of active links. You need to use another type of message, so the execution continues after pression OK in the message dialog.
