In my case it is a very long running action but even in the case of
short running actions I would think users would want to be able to
navigate away from the progress page and return. I thought maybe I
just didn't know how to configure the actions correctly....
EDIT: So while writing the above reply a solution occurred to me. With
a little trickery it's possible to do everything I was talking about
with no AJAX. Documenting this pattern below in case anyone else ever
comes across this problem.
Have a single Action that directs the users to the form view and also
handles the form submission. This solution will make it impossible for
a user to view the form again until their task is complete. The key is
to always use a delay for the execAndWait interceptor.
<interceptor-ref name="execAndWait">
<param name="delay">500</param>
</interceptor-ref>
The Action class looks something like:
public class LongAction extends ActionSupport {
private String formField;
public String getFormField() {
return formField;
}
public void setFormField(String ff) {
formField = ff;
}
public String execute() {
if(formField == null || formField.length == 0) {
return INPUT; //the form
} else {
//long task here
return SUCCESS; //result page
}
}
}
The delay on the interceptor is important because we need a chance to
return INPUT before being redirected to the wait page.
If anyone has a more elegant solutions please let me know.
Thanks,
