Hi Dan,
we use SAPUI Version: 1.24.4 and Core Version 1.24.3
In the examples it works the same way (it replaces the whole tab content instead of just toggel what is displayed).
https://openui5.hana.ondemand.com/explored.html#/sample/sap.m.sample.IconTabBarFiori2/preview
I think it would be possible to use some non SAPUI5 JS / CSS technics to achieve this, but i would prefer to stick with SAPUI5, so does any one knows a way how to do it?
We set the icontab-filters using the standard sapui5-databinding for odata-services. we update the description and icon(-color) of the tabs using an input field in its content. but the rerendering should be handled in the standard way (same as in the example above).
Regards,
Valentin
