- A long time ago, I made the following changes for the XDoclet 1.2.2,
in order to achieve this goal.
So, here is my changes:
1. from xdoclet-jsf-module-1.2.2.jar/xdoclet/modules/jsf/resources ,
take the faces_config_xml.xdt , and replace the current
<XDtFacesNavigation:forAllViews>
..........
</XDtFacesNavigation:forAllViews>
with the following one:
<XDtFacesNavigation:forAllViews>
<navigation-rule>
<XDtFacesNavigation:ifNeedFromViewId>
<!-- by cwele, from-view-id vise nije obavezno: -->
<from-view-id><XDtFacesNavigation:fromView/></from-view-id>
</XDtFacesNavigation:ifNeedFromViewId>
<XDtFacesNavigation:forAllRules>
<navigation-case>
<XDtFacesNavigation:ifHasFromAction>
<!-- from-action, added by cwele:-->
<from-action><XDtFacesNavigation:fromAction/></from-action>
</XDtFacesNavigation:ifHasFromAction>
<from-outcome><XDtFacesNavigation:outcome/></from-outcome>
<to-view-id><XDtFacesNavigation:toView/></to-view-id>
<XDtFacesNavigation:ifNeedRedirect>
<!-- redirect, added by cwele:-->
<redirect/>
</XDtFacesNavigation:ifNeedRedirect>
</navigation-case>
</XDtFacesNavigation:forAllRules>
</navigation-rule>
</XDtFacesNavigation:forAllViews>
2. take the NavigationTagsHandler.java, and replace with following one:
package xdoclet.modules.jsf;
import java.util.*;
import xdoclet.*;
import xjavadoc.*;
/** --- TEST PRIMERI
--- primer bez from-view-id:---
* @jsf.navigation
* fromAction="#{reportHandler.yyy}"

Hi,
I have been trying to use xDoclet to generate redirect attribute
for jsf navigation. I understood from XDT-1648 that it has been fixed
and that the fix is in a CVS version.
