Current behavior

This is an issue following the discussion here: https://forum.mbse-capella.org/t/type-issue-when-checking-for-diagram-existence/5103/5 In short: When using isRepresentationDescriptionName() on a collection (returns Sequence[bool]), all following calls of isRepresentationDescriptionName() in a conditional expression raise a The predicate never evaluates to a boolean type ([Sequence(boolean)]) error even when they are not checking on a collection.

This was tested by using three blocks of code

Checking on element -> No error
Checking on collection (error message circumvented by using ->exist(b | b) -> No error
Checking on element -> Error

Expected behavior

The third block should exhibit the same behaviour as the first block since it the code is identical.

Minimal reproduction of the problem with instructions

Example model and template provided here. ExampleProject.zip

What is the motivation / use case for changing the behavior?

Error should be consistently thrown for same code block regardless of position in document.
