Query with forms

Hello

 I am working on an application where I need to be able to do the following:

 Steps:

1. I have created a form where with a Cyclic field -Field 1 (choice ->None and Select from Layout)

2. After clicking "Select from Layout",  I select the instance from the layout view.

3. I want the instance name to be immediately populated in a string field in the form -Field2

I have put a procedure in the Callback in Field1 that gets the Instance name. However, the trouble is that the instance name gets populated in Field 2 only after an additional click on Field 1 (Ie change choice from Select from Layout to None). Clearly this  should not be the flow .

 I realize that the callback from Field1 is called immediately on click and the procedure is executed fully. Hence a second selection is required to enable transfer of data (geGetSelSet()) from layout to form.

 Is there a way to overcome this.

 What I want to finally have is something like what is present in cadence tools. Eg : Cadence ADE  ->Select Net from Schematic -> (On selecting net from schematic)--> Net name is populated in ADE form

  Skeleton code as below:

; FIELD1

pinSelField = hiCreateCyclicField(

      ?name           'pinSelField

      ?choices        list("None" "Select from EV View")

      ?prompt         "Select Pin"

      ?defValue        "None"

      ?callback        "GetPinInstance()"

);inpSelTypeField

;)

;PROCEDURE TO GET CELL NAME

procedure(GetCellInstance(frm frmSel)

prog((cell_view xx)

   cellSelect=geGetSelSet()

   cellName=car(cellSelect~>name) 

     if(!cellName then cellName ="none")

   RNetFileForm->instDisplayField->value =cellName

  ...

  )

 )

)

;FIELD 2 (Display Instance Name

instDisplayField = hiCreateStringField(

      ?name          'instDisplayField

      ?prompt         "Instance Name"

      ?value          "none" 

      ?defValue      "none"        

      ?editable       t

      )

I have just a couple of observations from your code in your post:

1. You said in step 2 that "After clicking "Select from Layout",  I select the instance from the layout view". Your callback runs as soon as you toggle that cyclic field. At that time, it looks to see what is currently selected. If you want to select the instance after you toggle the cyclic field, you'll need to use an enter function like "enterPoint" and process the instances under the point. This would be better implemented with a button since toggling the cyclic field back to "none" would be the only way to get the callback to run again. As the code is now, you can have the user select an instance in the layout first and then press a button on the form that calls the callback and that would work without need for an enter function.

2. Your pinSelField callback calls GetPinInstance. The callback you posted is named GetCellInstance.
