Description fch22 2026-03-23 13:39:29 UTC 
I have created some workflow in BQM including the base tools "assign caption"
The idea is to store some information during the execution of the job.
But I have a concern using it:
 I created a job with the text "caption1 text" in the "assign caption" tool. 
Execution is correct, but when I restart DK, the "caption1 text"  has disappeared from the "assign caption" tools of the job. My expectation is to get the "caption1 text" available for any further run of the job.

Hi Maik,

The patch look good. 

Note : The same issue exists for the title map to stream with the DOM hierarchy.
