Hello!
I am trying to use the math unit to update attributes of one entity. This is the model
https://www.dropbox.com/s/1vxd56gf5ryjzbc/Screenshot%202014-10-20%2012.33.35.png?dl=0
I added 2 operands then summed them in the static expression as stated in the documentation0
http://www.webratio.com/learn/learningobject/How-to-use-Math-Unit?link=oln72ae.redirect&nav=14&cbck=wrReq6081
I use data flows for the binding and to retrieve the result.
When I press the navigation flow to update the entity it doesn't generate errors and it follows the ok flow but in the database the attributes are not updated.
Am I missing something about the math unit? Is it ok to use it like that outside of a page?
