Hello Martin,
a central class in Webflow is PageFlowRequestCycleProcessor:
public class PageFlowRequestCycleProcessor extends WebRequestCycleProcessor
{
/** {@inheritDoc} */
@Override
public IRequestTarget_*resolve*_(RequestCycle requestCycle,
RequestParameters requestParameters)
{
//If Key in URL use it
if(requestParameters.getParameters().containsKey(PageFlowConstants.FLOW_EXECUTION_KEY))
{
String[] flowExecutionKeyParms =
(String[])requestParameters.getParameters().get(PageFlowConstants.FLOW_EXECUTION_KEY);
if(flowExecutionKeyParms.length > 0){
return
RequestTargetFactory.buildFromState(flowExecutionKeyParms[0],
requestCycle, requestParameters);
}
}
IRequestTarget target = super.resolve(requestCycle,
requestParameters);
// If the target is bookmarkable but mounted it needs to go
back and check pageflow
if (target instanceof BookmarkablePageRequestTarget)
{
// BookmarkablePageRequestTarget bookmarkableTarget =
(BookmarkablePageRequestTarget)target;
// if
(PAGE_FLOW_PAGE_CLASS.isAssignableFrom(bookmarkableTarget.getPageClass()) ||
//
PANEL_FLOW_PAGE_CLASS.isAssignableFrom(bookmarkableTarget.getPageClass()))
// {
String currentStateFromSession =
PageFlowSession.get().getFlowState().getCurrentViewState();
return
RequestTargetFactory.buildFromState(currentStateFromSession,
requestCycle, requestParameters);
// }
}
return target;
}
/** {@inheritDoc} */
@Override
protected IRequestTarget _*resolveHomePageTarget*_(RequestCycle
requestCycle, RequestParameters requestParameters)
{
//Grab the target as Wicket would normally calculate it
BookmarkablePageRequestTarget classicTarget
=(BookmarkablePageRequestTarget)
super.resolveHomePageTarget(requestCycle, requestParameters);
BookmarkablePageRequestTarget newTarget =
resolvePageFlowTargets(classicTarget,requestCycle,requestParameters);
//If the target that PageFlow is returning isn't the real home
page we need to redirect to it.
if(!classicTarget.getPageClass().equals(newTarget.getPageClass())){
//Redirect to the homepage if session is trying to go to
the end of the flow since we are restarting it
String currentStateFromSession =
PageFlowSession.get().getFlowState().getCurrentViewState();
if(PageFlowConstants.PAGE_FLOW_FINAL_STATE_DONE.equals(currentStateFromSession)){
//Reset the whole flow state in preparation for a new flow
PageFlowSession.get().resetFlowState();
// This line is to reset the target because the
flowstate was just reset so the url needs to be regenerated
classicTarget =(BookmarkablePageRequestTarget)
super.resolveHomePageTarget(requestCycle, requestParameters);
return classicTarget;
}
throw new
RestartResponseException(newTarget.getPageClass(),
newTarget.getPageParameters());
}
return
resolvePageFlowTargets(classicTarget,requestCycle,requestParameters);
}
/** {@inheritDoc} */
@Override
protected IRequestTarget _*resolveBookmarkablePage*_(RequestCycle
requestCycle, RequestParameters requestParameters)
{
//Grab the target as Wicket would normally calculate it
BookmarkablePageRequestTarget classicTarget
=(BookmarkablePageRequestTarget) super.resolveBookmarkablePage(
requestCycle, requestParameters);
return
resolvePageFlowTargets(classicTarget,requestCycle,requestParameters);
}
/**
* <p>resolvePageFlowTargets.</p>
*
* @param classicTarget a {@link
org.apache.wicket.request.target.component.BookmarkablePageRequestTarget} object.
* @param requestCycle a {@link org.apache.wicket.RequestCycle} object.
* @param requestParameters a {@link
org.apache.wicket.request.RequestParameters} object.
* @return a {@link
org.apache.wicket.request.target.component.BookmarkablePageRequestTarget} object.
*/
protected BookmarkablePageRequestTarget
_resolvePageFlowTargets_(BookmarkablePageRequestTarget classicTarget,
RequestCycle requestCycle, RequestParameters requestParameters)
{
BookmarkablePageRequestTarget target = null;
String currentStateFromSession =
PageFlowSession.get().getFlowState().getCurrentViewState();
//If the target still hasn't been set, target from the user's
session data
if(currentStateFromSession != null)
{
target =
RequestTargetFactory.buildFromState(currentStateFromSession,
requestCycle, requestParameters);
}
//TODO if the target is null, redirect back to the last
rendered page, or the homepage
if(target == null)
{
target = classicTarget;
}
return target;
}
}
For which Mappers should I look in these cases ?
Best regards

Thank you Martin.
Now I started another evaluation process after studying spring Webflow
and Seam
an especially this discussion
<http://http://ptrthomas.wordpress.com/2007/03/02/wicket-impressions-moving-from-spring-mvc-webflow/>
lets me think more profoundly about the subject.
In cocoon I tried the flow subject with spring apllicationXML files
After some time with growing XML-structures it was rather tedious to
find out the reason
of a flow problem. In wicket I tried it with HashMap in the
Wicketapplication.
But the maintenance became also tedious. After the above discussion I
think I will try it more with special Components and
and Inheritance.
Best regards

Hi,
Some guys created integration of Wicket 1.4 with Spring WebFlow (
https://github.com/wicketstuff/core/tree/core-1.4.x/jdk-1.5-parent/spring-webflow-parent
).
You may find it interesting and update it to newer versions of both Wicket
and Spring WebFlow.

Is there any support to structure the flow of pages and forms.
I build for my realestate software structures, defining a state of a page,
the visibility of the links and tabs, the pages a link calls in this state,
database action to be done and the pageparameters
the link tranfers to the new page.
But maybe there are more intelligent ways to organize this.
