@MikolajBuda How did you get the property to save? I have also overlaid
that path in order to add a custom tab to DAM folder properties however
the dialog fields within the tab are not being saved to the CRX upon
saving the dialog.
The issue is that the client library is not included on the page. I
added the client lib as shown below:I added this at the page
level for testing, however it might be more appropriate to add the
client library at a component level. It looks like the Adobe article,
Developing your first Experience Manager 6.3 Components, used the
We.Retail site as a starting point and so the client lib was already
included. I did not investigate to see how the We.Retail site was
including the client lib.
