How to change a Grid's parameter from a subclass of Grid?

[Aleksandar Nikolov]

Hi,

I extended Grid component because, among the other things, I want to 
integrate a Select component for choosing 'rowsPerPage' parameter of the 
Grid - for example by "10 20 50 100" rows per page values. Let's call 
ExGrid extends Grid. It is 5.3.8 Tapestry version.

So far so good, but how can I change 'rowsPerPage' parameter of Grid 
from inside of its subclass ExGrid?

Making that Select as external component and connect it on every ExGrid 
just works (<t:exgrid .... inPlace="true" 
rowsPerPage="rowsSelect.rowsNum"...), but I want to integrate it inside 
ExGrid. That's became headache because I cannot change the 'rowsPerPage' 
parameter from inside of ExGrid...

I believe that there should be a way to do this!

Please help!
