[TYPO3-english] Extbase - comma separated values select mapping on property

[Jan Bednarik]

Hi,

I wonder what is the correct way of mapping a select that's persisted as 
comma separated values on a property. At the moment I have the property 
as array which is working when setting the property from 
<f:form.select>. Problem is that the array is empty in the object that 
comes into the "show" action. So what to do with it?

Thanks

Jan
