Display Pop-Up based on tag value (boolean)

Hey folks! Quick logic question: I need a popup to trigger whenever a specific tag (memory tag) goes high. The catch is it needs to show up on every page (whichever one is currently open).

Does anyone have a recommendation for handling global triggers like this without duplicating the logic on every single screen? Thanks in advance!

Use a global docked view, and bind the tag to a view custom property within it. Add a change script to that prop that opens the popup.

Hi,

I went through a few posts posted in this forum for similar topic.

And i have come across this code

    popupId = "pop1"
    viewPath = "Nav Link"  # insert your view path here
    logger = system.util.getLogger("POPUP")
    sessions = system.perspective.getSessionInfo()
    for session in sessions:
        for pageId in session.pageIds:
            logger.info("{0} | {1}".format(session.id, pageId))
    
            if currentValue and currentValue.value:  # I added an additional safety check for first time use here
                system.perspective.openPopup(popupId, viewPath, sessionId=session.id, pageId=pageId)
                logger.info("openPopup complete")
            else:
                # note no viewPath arg
                system.perspective.closePopup(popupId, sessionId=session.id, pageId=pageId)

the pop up is not displayed in the page and got this error in the log

The whole point of my advice to use a dock was to avoid having to loop through session information. The change event on the docked view's custom property can be a simple one-line call to system.perspective.openPopup(). Perhaps another line to make it conditional.
