[TYPO3-dev] BE--Populate select field based on another field

[Ryan Hayle]

Anyone know if there's an easy way to do this?  When editing a record, I 
chose the first field,  then the second field is loaded with new values 
based on the first.  Either ajax or old-fashioned reload is okay.  I 
know it does this when changing page type, so there must be a way.  Of 
course ajax is even better. :)

Thanks,
Ryan
