Hi Max,
we talked with SAP ITS product owner Ralph Resech and he gives us good reasons, why SAP does not like to support a embedded browser by CL_GUI_HTML_VIEWER within the ITS framework ... it'll open pandora's gate to hell ;-) due the possibility of complex interactions between the embedded browser and the surrounding ITS environment. The result might be hard to support ...
So we had to find another solution ...
As our demand was not a full blown HTML browser within ITS (only a HTML subset of tables/spreadsheets), we were able to map the demand to IGS functionality.
We dynamically feed data to IGS and render the output in backend each time the ITS HTML page is shown. The IGS rendering output is a plain bitmap, which we can embed in ITS mobile screen now.
Maybe this may help you also
Best regards,
Matthias
