How to update the tags in component when tags are moved in aem content/cq:tags/a to content/cq:tags/b ,considering component has couple of tag fields and it has to be updated ?
These component references are not stored I checked all the ways but no luck!
Please share me the solution if anyone has it?
Hi Jyothirmai,
I have an old fiddle file, but you need to make your changes on top of it then execute in Fiddle by following safety measures mentioned above.
