Thanks for your response Jérémy. But as my business logic is very much tied
with session, editing context, I may need WOLongResponsePage.
Also, I have NOT integrated Project Wonder to my system and I only use few of
Project Wonder components here and there in my application. I hope to use
AjaxProgressBar I have to at least integrate Project Wonder's AJAX framework
(we know jQuery, we like it and we use it, but not Prototype.js which is the
core of Project Wonder's Ajax framework, sorry! for my privileges).
Correct me if am wrong?
Thank You,
Shravan Kumar. M

Hello, Why not using Ajax capabilities of the project Wonder like
ajaxprogressbar ? It's easy to implement except dealing with thread and session
if you're working with editing
context. jérémy -----webobjects-dev-bounces+jeremy.deroyer=ingencys....@lists.apple.com

Objet : WOLongResponsePage issues
Hi Group,
I am having trouble developing a long response page!!! I have developed a page
which extends WOLongResponsePage component and implemented performActionI(),
... methods. I have actually referred to SimpleRefreshPage example from
WebObjects distribution.
Am not sure what the problem is, but I have various issues:
1) Not able to create a component in "pageForResult()" method (error says,
context is null, ...). So I have created the component in the calling page and
passing the created component to long response and returning this component in
pageForResult() method. But I have read in WO that, if a component is created
and cached in a variable, we have to invoke ensureAwakeInContext(context)
method to make sure the cached component is awakened and is up in the session
store.
2) I have placed a flash movie (.swf file) in the long response page, so the
movie plays and replays as the page refreshes (this flash movie does not read
any value from long response page like: status of long response, ...).
3) Issue: The long response page is NOT refreshing and after some time "No
instance available" message is shown in the browser, but note that server is
continuing processing my request.
4) Below is the code snippet from my long response page:
Number refreshCount = new Integer(1);
public void appendToResponse(...) {
setRefreshInterval(refreshCount);
super.appendToResponse(...);
}
public Object performAction() {
Object value = processImages();
//value is of boolean type
return value;
}
/**
User & CImage are EO's and we using session's defaulteditingcontext
here.
*/
private boolean processImages() {
User usr = ((Session)session()).loggedInUser();
boolean isSuccess = CImage.processImages(usr);
return isSuccess;
}
public WOComponent pageForResult() {
return nextPage;
}
public WOComponent refreshPageForStatus() {
return this;
}
5) If anyone could advise me do's and don'ts of WOLongResponsePage coding and
best practices, that would be great. I see we are really missing nice
documentation on WOLongResponsePage usage.
Unfortunately, I cannot user ERXWOLongResponsePage.
Please suggest what am I doing wrong here/ probable solutions.
Thanks in advance,
Shravan Kumar. M
