Hi everyone, I am trying to capture the values entered into Promoted Filters in a Constellation Portal UI. My List View is backed by a Data Page that is sourced by a Data Transform. Currently, adding a value in the promoted filter does not trigger a network payload. Because of this, pyQueryPage is…

@SebastiaanH My comments were regarding using constellation-ui design system. Here is some more explanation how to exactly establish your usecase. Datapage should be set up as follows: Source must be set to report definition ‘Allow querying’ must be set to true Post datatransform must be set to …

Yes, Data Page has the checkbox on “Allow query using a JSON object (recommended for queries using many fields)“ and also the status set to API.

Ranjay_Singh_1 and SebastiaanH your question from Empty List on Load in Constellation Landing page - let get it answered here. I was under the impression from Source data for a table or list and CS docs like Authorization Inquiry that you could. However, based on: this unanswered post AND Questio…

@JorgeAlbertoR that’s why I missed this one originally! (its in General category :laughing:) Are you in the User Experience Expert Circle? I would like to move this under that area, so it can be found with other Constellation questions. However, if you are not a member you won’t be able to respond…

No, we had to block this requirement for the moment as all approaches followed didn’t gave the initial needed empty result.

I am not on the User Experience Expert Circle, I don’t mind if you move it, if that helps to get an answer to it.

We also tried this a lot but query page only construct when source is connectore or Local db report (as far as I remember) there is an article in 101 trying that approach of having a connector and service in own app and call connector from dpage and put data transform logic in service.

Can’t you suffice with using the param.pySearchPageName? In the view, you have a filter with some fields, and as a source, you have a queryable datapage. In the queryable datapage, as a source, you have a datatransform (pass parameters = true). In the datatransform, you have parameter pySearchPag…

Hi @RSIMONIS this only works inside a case. The steps you describe is used by us in a similar way in a search and select solution. However on a Landing page with a list view and promoted filters there is no parameter that can be used. At least I can’t find it anywhere.

OK, so short answer: If your source is a datatransform and you are using Pega 25.1.2 and you are using promoted filters in a landing page, Pega will not refresh the query (/datapage) because it doesn’t think the datapage is queryable (it will disregard the datapage checkbox), so the filtering happen…
