Problem with Right Transformations in tables #61

Closed markusvoelter closed 10 years ago

markusvoelter commented 10 years ago

There is an assertion exception that shows up when I try to execute a righ transformation in a table. I have submitted an MPS bug, since I thought this was an MPS problem: http://youtrack.jetbrains.com/issue/MPS-19008

However, since this (only?) happens in tables, it may be a tables issue as well.

I'm sure it's my fault. How can I reproduce that error?

Go to this node:

node: Motor [ConstantGroup] root: Groups [ImplementationModule] model: test.ex.utils.constantgroups module: test.ex.utils url: http://mbeddr.com/r:3a723734-50a2-46e2-bd30-172860df1b8a##__##3457387547011497667####

There's a table, and it has in the header. Press enter there, this gives you a VariantSelector represented as {expr}. Now enter an expression (such as "a") and try to perform a right transformation (e.g., entering && for logical and). This will reliably provoke the error.

This is what Alex says about this problem: This problem looks like connected with custom cell implementation (used for tables, i suppose). In the code MPS is just looking for a "big" cell for particular node. By default all such "big cells" are stored in special map inside an editor right after creation.
