[TYPO3-english] Grid Elements: unexplainable value in tx_gridelements_container column

[Matthias Kurz]

Hi,

in one of our projects, older entries in tt_content show a unexplainable 
value in the column "tx_gridelements_container": Altough the are not 
(and never were) inside a grid element, the value is "4" instead of "0". 
When saving, those entries get colpos = -1 (instead of 0) and therefore 
disappear for the backend page view.

New entries get correct values. The system was updated from 6.1x to 
6.2x, also grid elements was updated a is now 3.2.0. Has anybody 
observed such behavior? Would it be safe just to update the column?

Cheers, Matthias
