Hello I'm having a problem with T4.1.2
I' have a component with
<parameter name="startRow" required="no" default-value="ognl:0">
<description>
When you have a scrollable table, this is the index of the first
row displayed.
</description>
</parameter>
and its listener:
public void addNewListener(IRequestCycle cycle) {
callSubmitBeforeListener(cycle, getAddNewAction());
if (!CommonUtils.nullOrEmpty(getSource())) {
if (getDisplayRowCount() > 0) {
setStartRow(Math.max(0, getSource().size() -
getDisplayRowCount()));
}
}
}
When trying to call setStartRow this exception is thrown:
Binding with value 0 (ExpressionBinding[Home/tableForm 0]) may not be
updated. org.apache.tapestry.BindingException Binding with value 0
(ExpressionBinding[Home/tableForm 0]) may not be updated. binding:

What can I do ?
It seems to me that in previous T4.1.2-SNAPSHOT this didn't appear.
Please help!
Thanks in advance,
