hey guys,

I built a model on 3.5a version, and extracted it to a M file on 4.0a version.
Now, after I opened Comsol 4.0a with Matlab, and tried to run the M file, the following error came out:

??? Java exception occurred:
Exception:
com.comsol.util.exceptions.FlException: Invalid property value
Messages:
Invalid property value
- Property: descr

X is Y#Description#a string

Error in ==> model at 759
model.result('pg1').feature('surf1').set('descr', '');

Thank you very much in advance.

Hello,

I get exactlyt he same error with a file that was built in the version 4.1. Is your problem already solved in the meanwhile?
Thanks in advance for your answer.

Hello Chen,

I just found that my error was fixed by replacing the empty space'' by a non-empty string.

So replace
model.result('pg1').feature('surf1').set('descr', '') by
model.result('pg1').feature('surf1').set('descr', 'test');

or something like that.
