Not able to pass value from parent interface to child interface?

Can you provide some screenshot / code of your way of implementation ?

Also, did you try to test the interfaces individually, as in does the rule input gets updated in the parent / child interfaces

PARENT INTERFACE

rule!RLM_section_updateAssignee(
requestId: ri!requestId,
buttonValue: ri!buttonValue,
requestData: ri!requestData,
comments: ri!comments
)

CHILD INTERFACE

a!paragraphField(
label: "Comment",
instructions: "(" & 255 - len(ri!comments) & ")",
value: ri!comments,
saveInto: a!save(ri!comments,save!value),
refreshAfter: "KEYPRESS",
readOnly: false()
),

I want to pass the comment value from child to parent which I am going to use in process model.

I have test interface individually and it is working fine, but value is not passing from child interface

It looks okay to me

Can you check what are the data types of comment in both the interfaces?

data type is text for both the interface

I tested and it looks fine to me

can you share some screenshots?

If you check individually it will work, when you test with process model it will not work

it depends on how you have configured the process model.

Can you share that ?

Also, can you describe what happens when you submit the form, does the process continues with blank comments ?

when I give any comment in the field and click outside value get disappeared

Well, it looks like you have not configured your form in the process model correctly.

Make sure you are modelling your process correctly so that you can save values from a form.

spefically, ensure you have mapped properly your interface inputs in Activity class variables (Data - > Input tab of your User Interface) and you have a process variable getting them saved into

something like

You can configure your parent interface here in the node

got your answer, but I am calling process model from interface using a!process. Not configured my interface directly in process model

Can you explain your set up how you are consuming your parent interfaces and if the issue is with the parent interface only or the process what your parent interface triggers?
