4368	Internal error After merging the strings... @ comment and newline before equation	Jan Kokert	somebody	"Dear developers,

I noticed, that from time to time OMEdit will shrink my source code together when I manipulate my model graphically. At the beginning, it seemed random, but I narrowed it down to a single issue (took me a while).

'''The Issue:''' When a model contains a comment sitting in the very front of the line AND followed by one (or) more newlines (can have white spaces) AND followed by {{{equation}}} ({{{algorithm}}} is fine actually), so this:
{{{
#!modelica
  Modelica.Electrical....
// comment at the very beginning and followed by a new line

equation
  connect ...
}}}

then the error message will pop up, ''as soon as you move'' components in the DiagramView:

{{{
[C:/dev/OpenModelica64bit/OMCompiler/Compiler/Script/CevalScriptBackend.mo: 1054:13-1054:204]: Internal error After merging the strings, the semantics changed for some reason (will simply return s2):
s1:
model test 
  Modelica.Electrical.Analog.Basic.Ground ground1 annotation( ... ) 

...
}}}

Please find attached the example.

'''Finally, your code is screwed up (all comment are cluttered and new lines are removed).'''"	defect	new	high	Future	Interactive Environment			Internal error After merging the strings comment newline
