Steps to reproduce:
- in the routing dashboard addon, enable the main tab and the subtab to display routing tasks
- start anykind of workflows on documents
=> the content view shows open tasks, and selecting them shows associated buttons.
Problem: when the content view lists tasks of the same time (corresponding to the same process definition), most of the time, it's useless to check available buttons on each task. As this is costly, this needs to be optimized.
