Re: PageExpiredException - ajax request

2010-08-11 Thread sbrookes2 

Is it possible to restore a page once it has been removed from the PageMap? 
It seems to be possible based on this thread but so far I haven't been able
to work it out.

In the above code:
return
pageFactory.newPage(Class.forName(requestParameters.getPageMapName()),
params);

When I try to generate the page it returns null because the default PageMap
name is null.  What am I missing?


Also, forgive another dumb question but Igor I have been trying to figure
out where the pseudo-code you posted should go in the request cycle but so
far am lost.  Can you provide a few more details?
requestcycle rc=getrequestcycle(); 

response orig=rc.getresponse(); 
rc.setresponse(new noopresponse()); 
page.render(); 
rc.setresponse(orig); 

thanks,
Sean

This may be a silly question but can you shed some light on the line:
rc.setresponse(new noopresponse());

Specifically the reference to noopresponse.  Is that a reference to an
existing method in Wicket or something that needs to be written for the
solution?  I get the general gist of the proposal but am a little confused
by what this line is intended to to.

PageExpiredException - ajax request

2009-02-04 Thread sthomps 

I'm running into an issue with PageExpiredExceptions and ajax responses.

Here's what I would like to do.

1.  Have sessions timeout at 20 minutes.
2.  Once a session has timed out and the user clicks an ajax link on the
expired page - the link should process as normal and do whatever was tied to
that link - such as show a modal window.

Here's what I have so far.  The ajax link works but the returned response is
the entire page + whatever component was added to the AjaxRequestTarget -
because of the Page.render() I would assume.  It's starting to feel like
more of a hack and I'm pretty sure there's a better way to do this.


public class MyWebRequestCycleProcessor extends WebRequestCycleProcessor
{
protected IRequestTarget resolveRenderedPage(RequestCycle requestCycle,
RequestParameters requestParameters)
{
String componentPath = requestParameters.getComponentPath();
Session session = requestCycle.getSession();
Page page = session.getPage(requestParameters.getPageMapName(),
componentPath, requestParameters.getVersionNumber());
if (page != null)
{
return resolveRenderedPage(requestCycle, 
requestParameters, page, false);
}
else
{
// Try to resolve the page instead of throwing an 
expired page exception
try
{
page = newPage(requestCycle, requestParameters);

PageMap.forName(requestParameters.getPageMapName());
pageMap.put(page);

true);

requestParameters) throws Exception
{

PageParameters(requestParameters.getParameters());

{

}
else
{

requestCycle.getRequest().getParameterMap().putAll(((params)));
return
pageFactory.newPage(Class.forName(requestParameters.getPageMapName()),
params);

container.beforeRender();

// Render the page so wicket finds the markup for the

Thanks - that's the path I went down after i posted.  Didn't know if there
was a cleaner way or not.
