Opening page designer fails

[SimonOfHH]

Hi @martonsagi

Used version: v0.9.868

I'm having troubles using the page designer (both on existing objects and on newly created ones). If I click on any page in the "object designer" it fails with below error message.

The same happens when I'm using the "New" --> "Page" action from the main window:

I tested it in an existing workspace and on a newly created one (just used "AL: Go" for a blank app).

Are there any debug-information I can share to help you find the problem?

Cheers
Simon

Can you send me the output from the Output Window / AL Studio section?
Mostly the recent translation manager updates caused some regressions on Page designer. Do you have the generated xlf file in the workspace or it's the state before the first compilation?

Sorry for not being quicker - I didn't expect such a fast response 😅

Here is the output

Oh, and I don't have a translation file in that workspace. It's really just a Table.al-file and the app.json basically. Also I didn't build the project before I tested, but the result is the same even if I did build it before trying to access the designer.

[SimonOfHH]

And the next answer: it was a good hint with the translation file 😅 As soon as I activate the feature and generate the Xliff the Designer works 👍

So the problem only comes up, when translations are not active.

Thanks for the update. OK, so this is the same bug I'm working on. It'll be fixed this week (before BCBeerinar 😀)
