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; }

BR,

Marija

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

Ali, Murtaza
