      Hi!

Does somebody know how to get a GvValue from a SubPort?

>>GvValuesInfo ports;

GvValue* vinportA = ports.in_values[0];
if (!vinportA) return FALSE;   
if (!vinportA->Calculate(bn, GV_PORT_INPUT_OR_GEDATA, run, calc, 0)) return FALSE;

That is for a MainPort! But I don't get a GvValue for a SubPort! My problem is, that (for example) a constant node does not give his value to my Subport. Only the value I put directly in the AttributeManager of the node are correct.

On the first picture the constant nodes has the Real-Value "50" in his settings.

Could someone help me?

Thanks :)
