Just in case anyone uses this in the future, I believe you need the
following line at the bottom of the setIsRPCMethod() function:
context().request().setUserInfo( ui );
Otherwise, this works like a charm. Thanks Greg.

In you super component have a method like
public void setIsRPCMethod() {
NSDictionary oldUI = context().request().userInfo();
NSMutableDictionary ui;
if (oldUI != null)
ui = new NSMutableDictionary(oldUI);
else
ui = new NSMutableDictionary();
ui.setObjectForKey(new Boolean(true),
Session.RPC_COMPONENT_ACTION);
}
and then in Session have
public void savePage(WOComponent page) {
WORequest req = context().request();
if (req != null) {
NSDictionary ui = req.userInfo();
if(ui == null || ui.objectForKey(Session.RPC_COMPONENT_ACTION)
== null) {
super.savePage(page);
}
}
}
Then in any component action that is been called through RPC (AJAX)
just call the method setIsRPCMethod and you should get this problem.
HTH,

I have a little app that displays a page where the user clicks a
hyperlink that invokes a component action that starts a thread of
a long running process.
The page then displays again showing that the task in in-
progress. I then use javascript's XMLHttpRequest to get status
information periodically and update a section of the HTML on the
page to show the user the elapsed time, what it's doing, status
and stuff like that.
The javascript code checks the status of the task until it
completes. When the status is complete I submit the form on the
page to cause it to redisplay. However, when I do that I get this
error:
You backtracked too far.
The application backtracking limit of 30 has been exceeded.
Any ideas how to avoid this error?
The direct action that generates the page with the status
information that is sent to the browser is as follows:
public WOActionResults checkStatusAction() {
return pageWithName("TaskStatus");
}
TaskStatus component simply returns the XML containing the status
information for the running task.
The checkStatusAction is called by the javascript on the browser
using XMLHttpRequest.
I read the WebObjects documentation on page caching but I still
can't figure out how to avoid this error.
If anyone has any ideas please shoot me an email.
Thanks,
Ricardo Parada
