Custom parameters for microflow invocation - Mendix Forum

Custom parameters for microflow invocation

0

I have a following problem. Model is very simple: entity named Expression that records Weight which is ment to be manipulated by User:

 

On a push of a button (which is found within DataView that is rendering Expression entity) I would like to call a parametrized microflow that adds 1, 2 or 3 (depending on a button) to a Weight attribute of a current Expression.

 

Buttons call following microflow:

 

The problem is that I cannot parametrize button's invocation to this microflow. Button connected to a microflow implicitly takes as a parameter an Expression but I cannot explicitly add anything else to a list of parameters:

 

I really streched my imagination trying to use other widgets within that DataView but nothing worked out (even if it worked, it would be unresonable complicated for such a trivial problem). Obvious solution is simple: have a different microflow for each button. All three microflows are identical but one contains hardcoded +1, the other +2 and the last one says +3. That's no way to do things and I don't count that as a solution. I might have 10 button tomorrow...

 

Thank you all in advance!

Hi Eugen,

What you can do is create seperate Microflows that are connected to the different buttons. 

When clicking on button 1, MF for button 1 is triggered and provides the weight (1) to the AddWeight MF.

When clicking on button 2, MF for button 2 is triggered and provides the weight 2) to the AddWeight MF.

And so on. 

Hope that helps.

Cheers,

Jeffrey
