Changing icon dynamically does not work for tabs

Environment

• Platform version: 6.10.3

• Client type: Web
• Browser: Chrome

Description of the bug or enhancement

On a generic UI, add a tabsheet with one tab and a button.
in the postInit() of the controler do something like:

HasIcon btnIcon = (HasIcon) button;
btnIcon.setIconFromSet(CubaIcon.BOOKMARK);
HasIcon tabIcon = (HasIcon) tab;
tabIcon.setIconFromSet(CubaIcon.BOOKMARK);

Expected result: both the tab and the button has the "bookmark" icon.
Current result: Only the button get's the bookmark Icon

If I set an icon from the Studio (ex question mark), the tab shows the question mark icon but not the bookmark, so looks like it is not updated.

Hi,

Could you please attach a demo project that illustrates the issue or at least the complete UI controller class?

Here is a minimal project to reproduce it with a hack to have the icons updated
icon.zip

Changing the icon does not seem to refresh the display (nor in the postinit, nor in reaction to a button click). Removing and adding back the tabs to the tabsheet does show the correct icon though.

Thanks for your help and your reactivity!

Unfortunately, it is not that easy to fix this without breaking backward compatibility.

For now you can use Tab API to change icon dynamically:

tabSheet.getTab("tab1").setIconFromSet(CubaIcon.ANDROID);
tabSheet.getTab("tab2").setIconFromSet(CubaIcon.WIFI);
