Bug? Error 'given key was not present in the dictionary' in Designer

[Reproretro]

I built one very simple app to see how the system works.
Then I was trying to create a slightly more complicated app in the new version 5. I spent a while working in Designer (no device connected and I don't have emulators), but the designer failed with the above error. I saved it and reloaded it, but all the changes were lost.
I tried simple layouts, some worked, some failed with the error. E.g. I saved the default listing, opened the Designer and saved that, then added a panel, added a label, added a EditText, clicked on the panel, then clicked on the EditText again, and the error came up. On another occasion it happened when I clicked on the EditText after renaming the panel. But other times I follow this sequence and it doesn't fail, but when it does I seems to be usually when I click on an EditText. Note I have not added any code to the app, nor generated members.
It makes it difficult to have enough confidence in a system that might lose all my changes, and I noticed this error has been reported for about 4 years.
Has anyone any ideas on this one?

did you install 5.0 or 5.01? 5.01 might have those errors solved.

I don't think is fixed, I have 5.01 installed and I get that error. It seems you get that error if you delete a view in the designer.

 

[Reproretro]

My error was always when clicking on something in the designer.
So that is two sources for the error.
Every system has bugs, but I am a bit concerned that I am seeing a significant problem - which actually makes development difficult - so early, and as I said before this bug has been reported for at least 4 years.
Perhaps V4 was more stable?

The designer was rewritten from scratch in v5.00. There is no relation between any old issue and the new designer.

The first thing that you need to do is to update to v5.01 it will probably fix this issue.

 

[Reproretro]

Thank you. Do you have a link for 5.01?
On the Home page is says 5.00 is the latest version

I'm running 5.01, installed from scratch and I still see that issue.

Found a message on the forum that says the same download link we were sent for V5 download, now downloads V5.01
So I downloaded it.

Are you able to reproduce it? Can you post the exact steps required?

 

[NJDude]

Yes, just create a layout, add a couple of views, then remove one, BLAM! nice error.

 

[Erel]

Can you enable the IDE logs and post them? https://www.b4x.com/android/forum/posts/50478/
Did you rename any view? Did you delete a parent view?

 

[NJDude]

No, I didn't rename any views, just added 2, deleted one and the error popped up right away.

I'll do the log thing, give me a few moments.

 

[NJDude]

Here it is

By the way, you can also make it happen if you:

1- Add a label view (or any view)
2- use the designer script and do something, like e.g. Label1.SetLeftAndRight(0dip, 100%x)
3- Add another view, then delete it
4- Error!

After that point, you won't able to add any views since the "key" error keeps popping up.

 

[Erel]

Thank you. I will check it...

 

[Erel]

Can you post a screenshot of the error?

Are you working with an existing layout file?

How are you removing the view?

 

[NJDude]

No, brand new layout, brand new project, and I'm removing the view by selecting it and hitting the DEL key.

HERE is the screen shot.

What I did was:

1- Added the Label
2- Added a ProgressBar
3- Added the code to the designer script (label1...)
4- Selected the Progressbar and hit DEL
5- Boom.

Now I see it. It happens when you delete a view in "designer script mode". This option should have been disabled as the views are locked in that state.

It will be fixed. Please see whether you encounter this error in "non-designer script mode".

 

[NJDude]

Please see whether you encounter this error in "non-designer script mode".

How's that done?, you mean in code?

 

[Erel]

When you click on the script pane the designer switches into a read-only mode:

It returns to normal mode when you click on the properties grid.
