RibbonBar control displays blank – PB Docs 2022

In the installable cloud app, the RibbonBar control displays
blank.

Cause:

The script file (XML/JSON) that is used to create the RibbonBar
control is not selected and deployed with the project.

Solution:

1. Open the PowerServer project object, go to the Application page, select Files preloaded in uncompressed format and then
click Add Files in the External Files option group to add the
RibbonBar script file (XML/JSON).

2. Deploy the PowerServer project again to make the change
effective.
