The outcome of MGNLDAM-719 has been merged to docs master as:

file:///home/martin/dev/DACS/product-docs/6.2/Modules/List-of-modules/Digital-Asset-Management-module/Magnolia-DAM-JCR-implementation.html#_displaying_asset_sizes_in_the_asset_browser

However, the asset-size config only works in the tree view:

size-sorting only works in the tree view. In the list view, an error is produced, leaving an empty view:

2021-05-07 15:54:43,228 ERROR nfo.magnolia.admincentral.AdmincentralErrorHandler: AdmincentralUI has encountered an unhandled exception. com.machinezoo.noexception.WrappedException: javax.jcr.query.InvalidQueryException: '/' not allowed in name

Developer notes

Roman, May 7 via slack

Not working cause,

• in the tree view, sorting is done by Vaadin
• in the list view, it is the JCR query directly

Suggestion: 

Add a custom column for sizes in the list view.
