Assets handler upon save

[nbg62]

hi,

we created assets custom metadata schema form to allow users to add additional tags on separate tab, those tags are obviously not saved to cq:tags props upon save. What would be the approach to intercept save, extract tags from custom props (wlimgtag & wlsoltag). and save it to cq:tags property so that they are later available for assets search by tags.

Thanks

Hi @nbg62,

First of all you should rethink if you really need this kind of separation of the tags, maybe instead of having 3 different tag fileds (OOTB cq:tags and 2 custom fields) only one could be used, and distinguish tags base on namespace.

If that is not possible, and you still have to keep current setup, you can consider one of following options:

• Sling PostPorcessor - here is sample code: http://experience-aem.blogspot.com/2021/04/aem-cloud-service-sling-post-processor-remove-duplicates-...
• Property Merge POST Processor - I think this is exactly the case you have described - https://adobe-consulting-services.github.io/acs-aem-commons/features/property-merge-postprocessor/in...

Thanks Lukasz, 

I believe last link is in the line what we're looking for. Thanks
