This can be solved is in jwc definition I put:

When you have a scrollable table, this is the index of the
first
row displayed.
</description>
</parameter>
<property name="startRowProp" initial-value="ognl:0"/>
This behaviour seems to be changed.
Doesn't the default-value create a property by itself if I pass an
expression like ognl:0 ?
Please let me know if the solution is the one I have to adopt by now.
