Unresolved parameter in Linked composites

Hi Team,

I have recently updated the HOLD composite, to put partner phases to HOLD. Out of 4 Phase parameters I have been getting unresolved parameter error for 2 parameters even though the parameters are present inside the phase. Tried downloading the controller but it didnt work.

While executing the phase there is no issues but while downloading the unit we getting these errors for all the phases where this composites has been referred. How do we resolve this issue?

  As you are using linked composite for phase holding logic, expression will give parsing warning until all coded parameters are present in ALL phase classes where this linked composite is used. Need to create these parameters (though not used) in all phase classes where this composite is used.

  We had created those parameters in all the referenced phases. Downloaded the unit but still getting this error.

  If you are getting error while parsing expression in phase class or in unit verify then there is no point in download.
  Please perform below test to confirm issue:
  In one phase class where issue is replicating, break the connection of holding logic from composite ( make holding logic embedded for test purpose) and parse that expression.
