Has anyone successfully used a drop zone in fluid job data?

We are trying to use a drop zone in the fluid job data component (JOB_DATA_FL). The subpage registered to a drop zone has PER_ORG_ASGN.EMPLID and PER_ORG_ASGN.EMPL_RCD at level 0; JOB.EFFDT and JOB.EFFSEQ in a scroll at level 1. Our custom table is also in a scroll at level 1. (That makes 2 independent scrolls – One for the 2 JOB fields and one for the many custom fields.) The key to the custom table is EMPLID and EMPL_RCD. As such, it is NOT a child of PS_JOB. 

Here's what happens:

(1) When navigating thru the component, the data from our custom table is visible. That is, the system does select the correct data from the custom table for display.
