Internal error occured, When I try reopening my project, it always happens

[port_u_geese]

I've gotten myself into a pickle while working on a project. I'm using chrome, the technical data is:
foundIn = nb186a
faultData = com.google.gwt.event.shared.UmbrellaException: Exception caught: (TypeError) : Cannot read property '-1' of undefined.
I already tried searching for the same error in the forum, but, using autoload=false or code at app inventor didn't help. Also, I tried checking the file and I couldn't find anything wrong.
If someone could help, I would be grateful.

Instead of producing a description that can't be understood anyway, include your .aia file here.

I tried checking the file and I couldn't find anything wrong.

Upload it here so we can check it.

Alright, here it is:
AIAfileOfMyProject.aia (1.1 MB)

[Patryk_F]

A large number of Image components in screen2 cause an error? After removing a few, no error. It is possible that the size of the images should be reduced.

Here you go AIAfileOfMyProject1.aia (1.1 MB)

[Patryk_F]

What caused the error?

[Anke]

It was an error on Screen2, @Boban has the details ...

[port_u_geese]

Thank you so much! But, what was the problem with screen2, though?

[Patryk_F]

This looks like a bug fixed in the .aia file, because in the designer and the blocks everything looks the same.

[Boban]

For some reason Quadrado11 and Quadrado12 did not have position in TableArrangement1 and thereby error, now they do and I've also added a image for you to see them..

[Patryk_F]

I also wanted to enlarge the screen in the designer, but for me it looks like this after zooming in and still nothing was visible.

[Boban]

I can see it in tablet mode as well

Edit: I'm using Firefox...

[Patryk_F]

There may be a problem here. Because I Chrome ...

We often see issues with the Table Arrangement Component - safer to use rows of horizontal arrangements instead I think - the problems do not stop at the Designer, we have seen issues in the built App too. I thought it had been agreed to remove the Table Component from AI2.......

[Patryk_F]

I have used the table maybe once. Unfortunately, it does not work as expected. I also prefer to use several horizontal layouts. But I think an alternative to the table could be invented. For example, combining several horizontal layouts so that after entering the number of lines, the horizontal layouts will be added automatically.

[ChrisWard]

That might actually be part of the forthcoming round of improvements which include lots of good things. It all depends on the purpose of the table. If it is a static source of information, it's hard to beat an HTML table.

[Patryk_F]

There are also various table extensions. After talking to the developer of the extension, I think he would have agreed to deploy it to appinventor. There are many options.
