Duplicate of Modelica class with dot in class name leads to unstable OMEdit state

[Christian Kral <dr.christian.kral@…>]

Create a new empty Modelica class M in OMEdit. Make a double click on M, make a right click and select 'Duplicate':

Name: M.2

OMEdit hangs...

This applies to

Connected to OpenModelica 1.14.0~dev-26782-g1817194
Connected to OMSimulator unknown-linux

I cannot reproduce the crash with the latest nightly build on Windows. What I get is:

[1] 09:07:59 Syntax Warning

then the situation gets messy, because I see a model M.2 in the library browser which is obviously invalid, and there is no way to get rid of it.

@adeas31 I guess we should check that new class names do not contain dots, and reject them if they do. This also holds for "New Modelica class".

It reproduces just fine on Linux:

getConnectionCount(M.2) 09:22:03:517
140734638623360 09:22:03:517
#s#; 0.000000; 0.196000; 'getConnectionCount(M.2)'

...

getNthConnection(M.2,211213); getErrorString();
getNthConnectionAnnotation(M.2, 211213); getErrorString();
getNthConnection(M.2,211214); getErrorString();
getNthConnectionAnnotation(M.2, 211214); getErrorString();

...

[Martin Sjölund]

Of course I guess:

existClass(M.2) 09:22:03:423
Error occurred building AST
Syntax Error

being treated as true might be another problem... (Not sure if it did, but I suspect so)

[Adeel Asghar]

Fixed in 953cb00/OpenModelica.

Release 1.15.0 was scrapped, because replaceable support eventually turned out to be more easily implemented in 1.16.0. Hence, all 1.15.0 tickets are rescheduled to 1.16.0
