JSON data transform does not support page groups
According to https://docs.pega.com/bundle/platform-88/page/platform/data-integration/json-automapping-intro.html pega does not support JSON automapping of page groups (only pages and page lists are supported) Is there any indication on when (and if) this will be supported in future?
as an alternative we use pzGetPageAsJSON data transform to map the complete page, but that results in all properties being mapped as a string
so:
- "somenumber": "1"; in stead of "somenumber": 1;
- "someboolean": "true"; in stead of "someboolean": true;
- "somedecimal": "10.01"; in stead of "somedecimal": 10.01;
etc.
Is there some other workaround that returns page groups into "proper" JSON? (so not returning all properties as a string)

At the moment, there is no indication from Pega on when or if JSON automapping for page groups will be supported in the future. However, there are some workarounds you can try to get the desired JSON output.
One workaround is to use a data transform to convert the page group into a JSON string manually. You can use the "Java Object to JSON" method available in Pega's expression builder to convert the page group to a JSON string. This should give you the desired JSON output with proper data types.
Another workaround is to create a custom function that serializes the page group to JSON. You can use a third-party library such as Jackson or Gson to serialize the page group to JSON with proper data types. Then, you can call this custom function from your code to get the desired JSON output.
Both of these workarounds require some custom development work, but they should give you the desired JSON output with proper data types.

@Sumit Kumar one more question though
i want to serialize the complete case, which has 2 embedded page groups, so i do not want to serialize the page group alone
how can i do that with the "Java Object to JSON" method?
because when i disable automapping all properties in the "root" of the case are not serialized anymore and i need to explicitly map all properties (which i do not want to do)
On the other hand: Are Jackon or GSON provisioned with pega? Or do i need to import the jar files myself?

I run into the same problem with a page group not transformed to JSON. The workaround I found is quite simple. I created a single page property into which I added the page properties as used in the page group. Then I use a data transform to copy the pages. In the JSON data transform I am adjusting the output name and got the result I need. I am running the data transform to map the pages from the page group to the single page in the activity before I call the data transform to serialize the JSON:
