While waiting on the execution to finish, I start editing some node. Clicking outside of the node appears to collapse all nodes and order them in a single line. Video demonstrates the problem.

There are two problems here

  • GUI should not reshuffle nodes like that (restarting the projects brings the original layout)
  • there are some underlying crashes on the engine side

It appears that we end up with () being inserted for the value e.g.

    number6 =
        ()

by GUI? Language server?

Steps to reproduce:

  • select the node
  • enter a space
  • click outside of the node
  • all nodes are reshuffled

Avoid ArrayIndexOutOfBoundsException with no args (#9393)
3755f90 
The `null` check creates a new Array but always assumed a non-empty one which may lead to

Added a guard to prevent the exception. The flag will be useless anyway as we won't enter the for-loop in this case.

Appears to be introduced via #8743. Discovered while debugging #9389.

Reproduced; As currently numeric input accepts anything, we parse space and put it as "Block" node without lines, and probably then our "AST repairing system" inserts the parenthesis.

I think we should be careful in what is accepted in numeric input - the AST block should not be.

In this issue, undo is also broken sometimes.

This should also be handled differently in Ast.syncToCode--it could reject attempts to sync a non-block into a block, because that isn't safe in general.

We need to know what is the expected behavior here. Should the node be deleted, or should such edit be rejected?

Technically, it is fixed by #10457 - now there is no way to put just any code into widgets.

But the problem here may re-appear when implementing Code Input Widget - added a section there about repairing AST to not break graph.
