[TYPO3-mvc] 2 plugins share the same action/fluit-template --> flexform configuration interferes

[Tim Schoch | GSTALTIG]

Hi roland
the problem here is that the flexform settings are stored in the content-element record in the db until they get overriden by another plugin.
You can check that by changing a value, save, switch the plugin, save again, change plugin back to the one with the flexform 
-> the same values are set as before.

now when your page gets rendered with the «non-flexform-plugin» TYPO3 takes the values inside the flexform db-column and 
passes them to the view without checking if the selected plugin has a flexform. 

without testing I'd say: create an empty flexform config for your second plugin (maybe it needs a passthrough field?) which should 
override the flexform values stored in the db and you should be good to go.
