Hi,
I was trying to create a String containing a carriage return through an
OCLExpression such as 'random string'.concat('\n') and ended up with a
java String looking as "random string\\n" so OCL automatically escaped
my "\". Indeed the String is then exactly as I wrote it ... except it
means I cannot concatenate control characters in an OCL String.
Is that the expected behavior for OCL Strings? If so, is there a known
way to have a carriage return inserted into a String via OCL?
Thanks

Hi, Laurent,
The OCL Specification does not make any provision for handling of
control characters. What do you get if you simply embed a newline in
the string, as in
'this is
an example'
Actually, I had expected that '\n' would work. AFAIK, the grammar is
supposed to have implemented that.
Would you mind raising a bug?
Thanks,
Christian

Christian,
Well in my case embedding a plain new line in the String is not a
solution as the project I'm working is in its early stages and a plain
new line would have to be handled too ;).
I raised https://bugs.eclipse.org/bugs/show_bug.cgi?id=242880 to record
this problem.
