[MYFACES-3916] Wrong navigation handling for <if> clause on null outcome

• Type: Bug

Description

Outcome is null, but the following navigation case matches (even though "from-outcome" is present).

<navigation-case>
      <from-outcome>go_mainMenu</from-outcome>
      <if>#{!mainLayoutBean.isXS}</if>
      <to-view-id>/mainMenu.xhtml</to-view-id>
</navigation-case>

Specification says:
To match an outcome value of null, the <from-outcome> must be absent and the <if> element present.

For evaluation look at org.apache.myfaces.application.NavigationHandlerImpl#calcMatchingNavigationCase

perhaps especially at

if(outcome == null && (cazeOutcome != null || cazeIf == null) && actionRef == null)  {
  continue;
}
