Only variable references should be returned by reference in content_get_nested_elements()

Hi, we just switched over from cck 6.2 to 6.3 in order to use the mutigroup function which seems to fit some of the needs we have. We are seeing this error in our db logs..

here is our set up

cck field node reference auto complete
cck field int value used as a count

multigroup with these 2 items as childeren.

the idea is to be able to get a node ref of something in our system and add a count value to it.. aka the int.

In our dblog we are seeing this issue

Notice: Only variable references should be returned by reference in content_get_nested_elements() (line 2856 of /var/www/sites/all/modules/cck/content.module).

also when adding in data into the fields, and you click add field is the functionality supposed to clear the form elements, this seems like a bug?

Cheers and thanks for your hard work!
