one of the first results of our study group is a sample project that shows how to use a page control to build a application that can open multiple forms.
José and I have used that approach in our VCL application and we plan to migrate it to TMS Web Core.
The source code for the sample is available on BitBucket here:
We intend to build a DataSnap server connecting to the Employee sample DB of Firebird. Then we need to serve the data JSON arrays from a REST request.
Feel free to download the sample and play with it. It is one of the many sub-projects in the study, where ADUG members can participate.
