Fix filter definition on a 'search' content view using a 'Custom EL expression'

When defining a content view with flag Search content view checked, action filter is not correctly generated when setting a EL expression in field Custom EL expression in tab Enablement (btw Activation is better) of content view.

Enablement tab of content view in Studio

action's generated XML

You can see that the EL expression is not included in the action filter's definition.

    <action id="SUPNXP-17164_searchContentView_search_action" enabled="true" order="0" type="link" immediate="false" link=".">
      <category>SEARCH_CONTENT_VIEWS</category>
      <properties>
        <property name="contentViewName">SUPNXP-17164_searchContentView</property>
      </properties>
      <filter id="filter@SUPNXP-17164_searchContentView_search_action">
        <rule grant="true"/>
      </filter>
    </action>

BTW the tooltip on field Custom EL expression says it is a MVEL expression, shouldn't it be a JSF EL expression?
