Hello! I am using Papyrus for UML (version 4.2.0.201812120922) on Eclipse
Version: 2018-12 (4.10.0) for MacOS.
The context is a class diagram whereby I have to define an attribute constant to hold a regex expression. The attribute text value follows:

+ pattern : PrimitiveTypes::String[1]="\\d{1,2}" {unique}

I am getting an EMF error for this. "A Property with invalid text string found"
any thoughs of what could be wrong with this syntax?
with kind regards
Athanasios

Hi Athanasios.
I tried it using Papyrus 2018-12 (4.10.0) on Ubuntu 18.04 LTS and no EMF issue was raised. Even a validate model did not raise any issues.

I attached my Papyrus "project" export as reference.

Hello Carsten, thank you very much for the follow-up and help. Having specified the constant value initially without double quotes showed the EMF error, then having tried to use double quotes didn't fix the error which makes sense because I hadn't focused out of the selected attribute and let the attribute repaint with the new "correct" assignment. Really glad there is no bug with this. Thank you very much!

Oh well, it wasn't finally that. The handwritten assignment should have been placed after the curly block.

wrong

+ pattern : PrimitiveTypes::String[1]="\\d{1,2}" {unique}

correct

+ pattern : PrimitiveTypes::String[1] {unique}="\\d{1,2}"
