1730	problems with variability of records and warnings that its values are not assigned.	Michael Wetter	Michael Wetter	"If the model below is simulated using
loadModel(TestRecord);
simulate(TestRecord.myModelInstance);
getErrorString();

then the following error occurs:
   messages = ""Simulation failed for model: TestRecord.myModelInstance
   [/home/mwetter/proj/ldrd/bie/modeling/bie/branches/mwetter/openmodelica/TestRecord.mo:11:5-11:60:writable] Error: Component mymodel.p of variability PARAM has binding mytwo of higher variability VAR.

Since mymodel.p is a record in which all members are parameters, my interpretation is that its variability should also be PARAM as opposed to VAR.

If the line
    TestRecord.myRecords.myTwo mytwo;
is changed to
    parameter TestRecord.myRecords.myTwo mytwo;
then the model simulates, and computes the correct result mymodel.x=2. However, the warning 
   Warning: Parameter mymodel.p.r has neither value nor start value, and is fixed during initialization (fixed=true)
occurs despite that r is assigned the value 2 in the declaration of myTwo.
