We have a requirement to display the single select table from which customer selects single record on save or submit of the case in another tab the data to displayed as previously selected.
When save for later option on the case is selected in the tracer save option can view the data is sent on the pyworkPage, after this save call another refresh call is executed OOTB, which is opening the case on the tracer the data is not available due to which view is empty,
We have a question why constellation is so complicated with the fields like data reference, while trying to fetch the data from external system using rest the classes would be Int layer, we cannot refer Int layer class as data reference is this a huge limitation from Pega constellation, to achieve we might need to populate again into a data type class datapage instead of Int type data page.
For low-code app it should decrease development time, but sorry to say it is taking moretime than usual section based development.
