Personas 3.0 SP02: F4 help (search table) does not work

Hi Personas 3.0 experts,

I added a "F4 Help" control on UI, and did the followings (according to the knowledgebase doc), but when I click the F4 icon, I did not see the table column content for selection.

Steps to add F4 Help:

1. In admin, added F4 whitelist for a table "DEVACCESS" which has two columns, "UNAME" and "ACCESSKEY".

    table: DEVACCESS. Field: UNAME, Count: 10

2. in UI editing, set Table and Field to "UNAME".

Error: in UI click teh F4 Help - nothing pop out.

Anyone can help? Thanks.
