4368	Failed to merge Modelica text @ comment and newline before equation	Jan Kokert	Martin Sjölund	"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	closed	high	maint/1.12	Interactive Environment		fixed	Internal error After merging the strings comment newline
