how to pass a cdt through an interface

In this case your Interface Output save for pv!User_Data is overwriting your interface updates.  Only the Save Into from the Input tab is correct, you will want to delete the Output Save Into, as this is overwriting with the pv! value (what the variable was set at prior to the form save).  If you had used ac!User_Data in the output this would function correctly but be redundant. 

thanks I removed it and the other  redundant things but it still does not save anything.

like there is no difference to the variables before and after

here is my process now

Can you confirm what your interface a!save()'s are now, and a screen shot of the node's Output tab?

In the first screen shot, the input variable is ri!User_Data, however the a!save()'s are using ri!GFIM_User_Access_User_Information.

In the second screen shot the variable name has changed to "userInformation".

Is this input being saved into within any other interface fields, or only on the Approval button save?

here is the output tab

here are my a!saves

I hope my screen shots answered your questions,

yes I am saving into that pv either if I approved or rejected

Thanks guys!

it  is late Friday... Have a great weekend ,

This all looks basically right unless I'm missing a subtle detail again.  When on the form designer, can you confirm that clicking "approve" and "reject" sets the value of ri!userInformation as you're expecting?  What does the value end up being when you view the PVs in the running instance after submitting?

my whole problem is that clicking the submit/ reject does not affect the PV's . I cannot understand why

I'm specifically asking you to confirm the values you see in the rule inputs panel when in the interface designer, though.

That should be the first place you test/troubleshoot.

so:

and ?

thanks for looking at this with me   Have a great  weekend! talk to you Monday

So in the Rule Inputs section (which you've pictured the left half of in your second screenshot), what is the value contained in ri!userInformaton after you click either button?  That's where you should be looking first to make sure the saveIntos are working.

As Mike notes, please expand the userInformation variable in the Rule Inputs area to verify data is saving on the form, when you click your buttons in /design.  Additionally, remove the "a!save(ri!userInformation,ri!userInformation)" in both submit buttons.  Once we can confirm data is saving on the form we can move to monitoring the process instance to review variable updates in Process History.

Shoot, I missed the fact that that was still there - it was the first save previously i think, so wasn't looking at the end of the save list.  luckily i think in this case it wouldn't be causing anyhing to get lost since the a!save()s are executed in order, so it would just be (redundantly) saving its current value back into itself.

it works! thank you guys so much!

for anyone checking on this later the bug was solved by making sure that there were no duplicate saves.

here the code that works for anyone that is checking later

 buttons: a!buttonLayout(
    primaryButtons: {
      a!buttonWidget(
        label: "Approve",
        icon: "check",
        value: true,
        saveInto: {ri!userInformation.supervisorDecision,
        a!save(ri!userInformation.supervisorsDecisionDate,now())
          },
        submit: true,
        style: "PRIMARY"
      )
    },
    secondaryButtons: {
      a!buttonWidget(
        label: "reject",
        icon: "exclamation-triangle",
        value: false,
        saveInto: {
          ri!userInformation.supervisorDecision,
          a!save(ri!userInformation.supervisorsDecisionDate,now())
        },
        submit: true,
        style: "DESTRUCTIVE",
        validate: false
      )
    },
    showWhen: or(
      isnull(
        ri!readOnly
      ),
      not(
        ri!readOnly
      )
    )
  )

Great!
