Thread On A Page (Web)

This agent is designed to be run by web clients clicking on a link in the
standard discussion database, it works in rel 4.6 & 5 & possibly 4.5. The
function is to display the main topic & any responses on one web page - no more
jumping around the thread map!
Call the agent 'ThreadPage', make it shared, run manually from the action menu
& 'run once (@commands used)'. Main Topic form has a field called MainID with
the formula:
@Text(@DocumentUniqueID)

Response forms have the same field but inherit from their topic.

Create a link to the agent with an action hotspot with this formula:

db := @ReplaceSubstring(@Subset(@DbName; -1);"\\":" ";"/":"+");
@URLOpen( "/" + db + "/ThreadPage?OpenAgent&unid%" + MainID )
