[TYPO3-ttnews] Having trouble with single's "back to list" link cHash and parameters

[John Kallies]

My client is a corporation with a dozen departments, each with a 
departmental sub site (different template/css, dept-specific menus, 
etc.). I'm using tt_news for a few different kinds of news articles:

  - individual articles in a monthly newsletter
  - promotional material for "coming events" (not calendar entries - more
    like flyers that auto archive after the event)
  - typical one-off categorized news articles

My concern in this message is how to display the various lists of news 
records. I need a list at the corporate level of all "coming event" news 
records, and a department-specific list of the events categorized only 
for that department.

I have a category for "coming event" records. In addition, each 
department has its own category (these categories have single-view pages 
defined). Via TS, I have categoryMode = 2 (only show records having all 
selected categories). Each category has a single PID defined in the 
category. I have the category for the desired single PID listed first on 
the news record.

My problem:

When selecting a given event news article from either the department or 
the corporate list, TYPO3 correctly goes to the single page as defined 
by the category. But the single article's "Back to List" link URL has a 
cHash that somehow causes the "Back to" list to not show the news 
articles that are defined in the plugin's Flexform.

I set "dontUseBackPid = 1" via TS. I understand that cHash more-or-less 
gives a unique code for cached objects. Clearly, I don't understand 
enough about managing this to overcome my issue here.

Also, categoryMode = 2 isn't an option via FlexForm, so to my 
understanding, the Flexform will override this value with one of the 
three values in the drop-down. The categoryMode = 2 could never work 
unless the plugin was defined purely by TS. Am I correct? Should I try 
to hack the flexform? (don't really want to)...

Would someone please give me insight about managing these back links and 
setting the correct categoryMode?

Thank you...
