I want to include one template nested into others cont1, cont2, cont3. And nested template should be hide one specific control for cont1 only. Before inclusion into cont1 I would like to assign value to some flag variable $hideMyControl.

And inside nested template I would like to check if $hideMyControl is assigned value.

How to perform such check?
