Hi,
It looks like Competition property should be of type string instead of Tag, since PropertyTag must be returning a string?
public virtual Tag Competition { get; set; }
Try with this instead:
public virtual string Competition { get; set; }

Hi Marija,
Thanks for reply. I have figured out the issue and it was related to backing type registration in episerver. In Admin section the registered the type of Competition was String i updated the type to Tag and TagList for other properties and it started working.
Cheers
