Dock won't open, UUID string too large

I’ve been working on an error message for a form. When the user forgets to fill out a part of the form a docked window should show up with a dynamically changing message telling the user what part still need to be filled.
However my code is spitting out an error that I don’t understand. Here it is:

 com.inductiveautomation.ignition.common.script.JythonExecException
Traceback (most recent call last):
  File "<function:runAction>", line 5, in runAction
  File "<custom-method Add>", line 95, in Add
java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: UUID string too large

	caused by org.python.core.PyException
Traceback (most recent call last):
  File "<function:runAction>", line 5, in runAction
  File "<custom-method Add>", line 95, in Add
java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: UUID string too large

	caused by IllegalArgumentException: UUID string too large

This is my code:

import time
params = {"Text":ErrorStr, "bgColor":"#FF0000", "Color":"#000000"}
		
system.perspective.openDock("Error", params)
time.sleep(5)
system.perspective.closeDock("Error")

The view has a DockID that matches the one in the code.

Does anyone have an idea what might be the problem?

It looks like you’re passing the arguments in a positional fashion, which means that “Error” is being interpreted as the id argument, and your params variable is being interpreted as the sessionId argument.

Try this and see if it works.

system.perspective.openDock(id="Error", params=params)

That seems to have solved it. No error message anymore.
Thanks!

That being said, the dock still doesn’t open, I’m guessing that might be because I’m trying to open it from a pop-up?

That shouldn’t matter. Have you created a Docked View for the Page which is currently visible, AND specified that this dock’s id is “Error”?


I’m pretty sure I do, unless I’ve overlooked something. This is on shared settings.

That should be absolutely fine.

Some things to check:

  1. This won’t work in the Designer - it only works in Sessions.
  2. Verify the View path is accurate.
  3. Check the Gateway logs to verify there isn’t an issue executing the script.
  4. Make sure you’ve saved the project.
  5. I just noticed that there is an ErrorStr variable in your params object, but I don’t see that defined anywhere

Well, after checking all those things seemed to already be in order, but I made sure anyway. It seems to work now and show the custom error message. It seems to also close the popup after closing so that’s a bit of a problem, but it’s better than it was before.

As for the ErrorStr, the parameter is called Text and ErrorStr is the variable I’m passing into it. It’s a HTML string that gets filled with a different message depending on what is missing from the form.

I was just letting you know that I don’t see that variable defined in your script before you use it, so I was expecting it to possibly fail.

I just tried your code (minus the params) and my Popup did not close. Consider checking that you don’t have some other code somewhere designed to close your Popup.

Fair enough
I only posted the relevant part of my code.

You’re right, another piece of code closes it. That solves that then.
Thank you, it should all work properly now.
