> Key: JBSEAM-4120
> URL: https://jira.jboss.org/jira/browse/JBSEAM-4120
> Project: Seam
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.1.1.GA
> Environment: OSX 10.5, Java 1.5, JBoss 4.2.3, Eclipse 3.4
> Reporter: Bob Shanahan
> Assignee: Norman Richards
> Priority: Minor
> Fix For: 2.1.2.CR2

>
> Prior to upgrading from Seam 2.0.x to 2.1.x, it was possible to define (without schema validation error) a page navigation from-action using page parameter variables. In fact, it was the only way get parameterized page from-actions to work.
> Given the following xhtml:
> <ui:include src="exportsTitleBar.xhtml">
> <ui:param name="title" value="#{messages.acctSummaryTitle}" />
> <ui:param name="exportActionBean" value="#{acctManager}" />
> <ui:param name="action" value="exportAcctSummary" />
> </ui:include>
> page navigation in pages.xml is defined as follows:
> <page view-id="/view/acctSummary.xhtml">
> <navigation from-action="#{exportActionBean[action]}">
> <rule if-outcome="pdf">
> <redirect view-id="/view/pdf/acctSummary.xhtml"/>
> </rule>
> <rule if-outcome="xls">
> <redirect view-id="/view/xls/acctSummary.xhtml"/>
> </rule>
> </navigation>
> </page>
> Using the actual bean and action, as in <navigation from-action="#{acctManager.exportAcctSummary]}">, does not work.
> While <navigation from-action="#{exportActionBean[action]}"> functions correctly with Seam 2.1.x, the pages-2.1.xsd produces a schema validation error due to restrictions of the from-action-expression... and ultimately the pages:method-expression, which is defined as follows:
> <xs:simpleType name="method-expression">
> <xs:restriction base="xs:token">
> <xs:pattern value="#\{.+\..+\}"/>
> </xs:restriction>
> </xs:simpleType>
> Either the page navigation from-action should be expressible via the actual bean and action or the method-expression should allow specification of a parameterized bean and action.
