Sorry, I forgot: Tapestry 5.

Hello,
in my template, I'm using a grid similar to this simplified model:
<t:grid source="gridObjects" row="currentGridObject" model="gridModel">
<t:parameter name="someCell">
${someFunctionGeneratingSomething}
</t:parameter> </t:grid>
When i comment out the parameter block, it is significantly faster
compared to when getSomeFunctionGeneratingSomething() is called. (When
it costs 2 seconds to show 4 gridObjects without someCell, it will
cost 4 seconds with it.)
At first I thought the database calls in
getSomeFunctionGeneratingSomething() are consuming the time, but then
I replaced it with a simple "return 0;" - and still it consumes almost
4 seconds, the difference was minimal.
I "solved" the problem by constructing a class dedicated to presentate
my gridObjects (simply wrapping them, so that all properties are
copied and a property does what getSomeFunctionGeneratingSomething
would be doing). That works, but it would be quite a bother to
construct this for all classes I want to output; it would nearly
double my work with them, not to mention the maintainability.
Why is this so time intensive? Is there any better way to solve this?
Thanks,
Tobias
