v8.1rc1 Is it possible to check if an Embedded View path property value is valid? I want to hide the component if it’s not, as I’m using a generic structure to generate the path, where some instances don’t have the item. Essentially, I’m asking if there’s a function to check if a View path exists? …

I filed an internal ticket a long time ago to add a system.perspective.getViewNames() or similar tool for introspection, along the lines of the Vision function. That’s probably your best bet here.

I posted a proposal on another thread that I think will solve this ask.

Was anything like this ever implemented? I’m running into the same issue again (albeit in 8.1.5) where I’m using an Embedded View where the view path is dynamic. Often the path will be invalid (which is valid) and in these cases I want to hide the embedded view. I don’t see a way to do this. For me,…

Maybe there is a easier way but this works xd It checks if the resource folder of the view exists^^ def viewExists(viewpath): from com.inductiveautomation.ignition.gateway import IgnitionGateway context = IgnitionGateway.get() pathToProjectFolder = str(context.systemManager.dataDir.abs…

Haha, that’s works. I didn’t even think about doing it that way, cheers. I’ll use that for now I guess for speed I could cache a list of all views found updated periodically or on trigger (eg designer save) and then read from that instead. I’ll see what kind of delay I get, shouldn’t be too bad tho…

i dont think there is going to be any noticable delay. but i havent tested it with crazy deep folders xd it just takes about a milisecond or 2 for my views so xd [image] [image]

[image] victordcq: about a milisecond or 2 My operators will probably still complain :joy:

average human reaction time is about 250milisec so i think you’re safe :stuck_out_tongue: even the fastest reacting animals (fruit flies?) need 5ms

system.perspective.getProjectInfo() returns a views array, you can check that for the view. Probably substantially faster than filesystem access.

Apparently yes, Carl posted this in the thread he linked: [image] Automatically creating Perspective Navigation Ignition Early Access We ended up implementing this as a scripting call after all. The json shape I indicated above will be returned from session.getProjectInfo(…
