[news.eclipse.platform.rcp] AboutDialog does not show feature button alt

[Daniel Krügler <dsp@xxxxxxx>]

Hello,

recently I tried to make my RCP app feature-aware.
For testing purposes I just added all currently
implemented plugins into its plugin list, set the
id of the branding plugin properly and changed my
.product file of that branding plugin to be based on
features instead of plugins -  Nice!
While the app worked fine after that, I wonder, why
the ABOUT action, which is provided in my workbench
action builder, does not show the expected "Feature details"
button in its AboutDialog. Does anyone know, what I
additionally need for its activation?

Thanks in advance,

Daniel Krügler
