Hi Rajesh,

What I tend to do, if you have just a few components with "attributes" 
which may have to be computed, is to use it as a method, and in the 
autohandler, the method reads the attribute as a default behavior.
Your way does not work because the component is parsed and split into 
its Mason portions before any Perl it contains is executed.

Example:

In /autohandler:
<%attr>
    search => 0 # default value if not given
</%attr>
%
<%method search>
% return $m->request_comp->attr('search');
</%method>

In /static_component.html:
<%attr>
    search => 1
</%attr>

In /dynamic_component.html:
<%method search>
% return $cat > 0;
</%method>

Then, when trying to use this, you replace $m->attr('search') by 
$m->scomp('SELF:search') or any other Mason method calling.
