In the page logic descriptor, you have to change (create a custom descriptor) the xml part related the UnitComputations
<UnitComputations>
<UnitComputation unit="inu2x">
<NavigationCondition selectiveRefresh="true" effects="#pr#"/>
</UnitComputation>
<UnitComputation unit="inu1x">
<NavigationCondition selectiveRefresh="true" effects="#pr#"/>
</UnitComputation>
</UnitComputations>
In this simple example the first component executed is inu2x and after the inu1x component.
