Hello,

does anybody know, how to get objects from the returned Custom Cache?  
Actually, everything comes back, but is only a Hash, it seems…

#\<Survey id: 11, uid: “006CC623A9B”, targeted: “for\_me”, name:  
“ohjlj”, description: “

kjopo

”, startdate: “2009-05-30”,  
enddate: “2009-05-31”, status: “building”, created\_at: “2009-05-24  
21:23:30”, updated\_at: “2009-05-24 21:23:30”\>

> > @surveys.first.is\_a? Survey  
> > false

Can anyone help me out here?

Greetings

Rafael
