<view-state> tag - popup="true" should support expression language [SWF-1251]

[spring-operator]

Michael Isvy opened SWF-1251 and commented

The view-state tag contains a "popup" attribute as follows:

<view-state id="changeSearchCriteria" popup="true">
     <transition on="search" to="reviewHotels">
          <evaluate expression="searchCriteria.resetPage()"/>
     </transition>
</view-state>

It would be nice if it was possible to use expressions inside the "popup" attribute as follows:

<view-state id="changeSearchCriteria" popup="booking.myCondition">
     ...
</view-state>
