Rule Input passing issue.

Values normally move from Parent to Child. So when C changes a value and sends it to B, B gets the updated value correctly. But A will not automatically get that updated value unless B explicitly sends it back to A using a save. A still has its own original local value. Since that local value is not updated when B or C changes it, A keeps showing the old value or resets during refresh. To make the updated value reach A, B must save the changed value back to A explicitly.

Are you experiencing this behavior in the Interface Designer or just in a User Input Task?

FWIW there is basically no limit to the number of parent/child levels that values can be referenced across, but the configuration has to be correct and may sometimes get tripped up due to factors more complex than a 1-sentence description of the issue. Any additional details (and/or screenshots or code snippets of your configuration across the various levels) would be helpful if the prior replies haven't already helped you solve it.

Pass the rule inputs from A to B using keyword syntax and similarly from B to C. The refresh variable definition at A might be hindering the value reflection between the three interfaces. So dont use a!refreshVariable in interface A but have the keyword syntax take care of sync between all variables.

If ri! Resets to null:
A has a local! variable overwriting the rule input on refresh. -> Remove/fix that reassignment.
Never receives the value :
B is not forwarding the rule input to A. -> In A, explicitly bind ri!value: ri!value when calling B.

ri! don't auto-propagate - each level must explicitly pass them.
