[z3-five] using getToolByName in utility

[Dennis Schulz]

Hello Yuppie,

I looked at EventTypeVocabulary in CMFCalendar.browser.event. 
In the Utitily itself I cant see any difference to mine.
Can you tell where it is used?

I my case does it make I create an adapter in the applychanges and then use the context of the adapter instead of the adapter?

set(adapter,newvalue)

Thanks,
Dennis
