That is correct for a new variable, I missed that part from your previous remark. So that is where converters come in. OK, if I find the time, I'll have a look. But if someone else has an idea.... Maybe using the variable-type from the PD and do some conversion before posting IF the type is not already correct. Or maybe filling the hasmap not with strings (default) but with objects created by using the variable-type from the PD. IF for the variable type we define java types View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3965541#...
