I am not able to add js to my dilaog ..I tried includeclientlibs node and categories=cq.authoring.dialog as well ....
Please let me know if I m missing something here dialog validation
you can add clientlibs to specific to dialog by using extraClientlibs property
The problem with your dialog could be -
Entry missing from js.txt
I hope you testing this with editor mode</editor.html/URL>?
