The default binding for rowsPerPage is to a static default .... 20.
Unless you bind rowsPerPage to a property, it stays bound to the default.
Most non-property bindings are readonly.
Chainging rowsPerPage means writing a value through the binding ...
here changing the field attempts to up∂ate the binding, which doesn't
support it.

Hi,
consider the following code:
[ in the template ]
| <table t:type="grid"
| t:id="EntryGrid"
| row="entry"
| source="entries"
| model="entriesRowModel">
[ in the page class ]
| @Component(id = "EntryGrid")
| private Grid _grid;
[...]
| private int _rowsPerPage;
[...]
| public void onSuccessFromGridForm() {
| _rowsPerPage = getNewRowsPerPage();
| _grid.setRowsPerPage(_rowsPerPage);
| }
Whenever I call `_grid.setRowsPerPage()' I get the following
exception:
| org.apache.tapestry.ioc.internal.util.TapestryException
| Failure writing parameter rowsPerPage of component MyForm:entrygrid: Binding
| [EMAIL PROTECTED] is read-only.

What am I doing wrong?
