Property expressions are rooted on the instance corresponding to the template.
So you could define a getRowsPerPage() property in Index.java and
reference it in your template:
<div t:type="xy/somecomponent" rowsPerPage="prop:rowsPerPage" source="xyz"/>
Then you could pass the same property to some other component and they
would stay syncrhonized:
<div t:type="xy/othercomponent" rowsPerPage="prop:rowsPerPage"/>
So the page "drives down" values into its embedded components.
If you want a more coherent answer, ask a more coherent question, such
as "my page needs to synchronize the parameters of two seperate
components" or even "I need this same value used in several places in
my page". Often when you ask for a specific technical question about
an API the best you can get is an answer about the API, not a solution
to your real problem.
