Parameter tags are not handled in component properties.

[sergeymorkovkin]

Documentation states: Parameter tags are used to insert application parameters at the place where they appear in the template.

However, whe using the following construction, parameter tag is not handled:

<com:TImage ImageUrl?="<%$ Website %>/Images/picture.gif" />

This results:

<img src="&lt;%$ Website %&gt;/Images/picture.gif" />

See page 76 of Prado QS:

Parameter tags are used to assign application parameter values to the corresponding component properties.

Parameter Tags are not evaluated in attribute values. Please use expression tags instead.

I'm a bit unsure if we should allow this.

Anyway, this is working:

<com:TImage ImageUrl="<%=$this->Application->Parameters['Website']%>/Images/picture.gif" />
