Hi There,
I was wondering if I could get some clarification around something in the documentation here:
forum.appian.com/.../Adding_Node_Inputs_and_Node_Outputs
Specifically this statement:
"Expressions for node input values are evaluated before expressions on the form. If the default values of form fields are mapped to node inputs, then they are evaluated at the same time as the node inputs. Therefore, they must not reference other node inputs."
If I'm understanding this correctly this means that input parameters on forms cannot be used for any default values on any forms - however this goes against what I'd thought were several Appian best practices and causes some very significant technical problems when displaying database data on a form.
Can anyone clarify what, exactly, is meant by the above statement and if I've misinterpretted it?...

Hi Angad, that has always been my understanding as well however the documentation explicitly states:
'If the default values of form fields are mapped to node inputs, then they are evaluated at the same time as the node inputs. Therefore, they must not reference other node inputs.'
which is where I'm getting confused - am I misinterpreting the documentation?
