Hi Saryu,
First a quick tip to improve readability and maintainability of your app: the coding convention for microflows which are use as datasource microflows is to use the prefix DS_ (https://docs.mendix.com/howto/general/dev-best-practices/#343-page-based-microflows)
Second, it looks a bit weird to me that you create an object that you use for the search filter (ACT_CreateNewGambaObjectForSearch) which is of the same entity as the objects you are searching. I would separate the two in different entities, so you have a clear separation of concerns.
Finally, i think you need a third microflow, which is the on-change microflow attached to the “Gemba change” field. The only thing that microflow needs to a refresh the Gemba object it receives. The refresh triggers a reload of the list view.
Does that do the trick?
Could you please elaborate more with screenshot?
Please find the image and microflow ss I used dropdown for selecting a Gemba Stages After selecting gemba stage search result should get according to that selected value. I got result correct when I debug the microflow I got filter list according to selected Gemba stage but it is not showing on the page , It is showing whole list of gemba.Could you please help me on that?
