Hello David,
the handling of the request seems to have an issue if you cannot get all the parameter.


If this is not a bug and is intentional behavior, shouldn't WebObjects be able to restore the session and read the wosid in the URL?

In performActionNamed(String name) when I call existingSession() on the URL with the escaped &, WO doesn't find the session. It returns null on existingSession() for a URL like this:
.../wa/ReminderDA/refreshReminder? id=46&amp;wosid=B6fPodDWHmwlDcUs54Uaj0


However, even if I add a third parameter to the URL and use formValueForKey, it doesn't work.
.../wa/ReminderDA/refreshReminder? id=46&amp;test=hello&amp;wosid=B6fPodDWHmwlDcUs54Uaj0


formValueForKey works on id but doesn't work on test or wosid.
I'm quite surprised you cannot get wosid (or test) using formValueForKey...
The example I have in mind is using the wosid, we are not manipulating it, but the application is using it and manage the session correctly, so I think there's something...unexpected.




If I remove the escape characters, existingSession() works and formValueForKey works properly.
You can do that of course, it is just something that could break sometime as it is just not HTML.

Do you mind sending your entire method so we can have a look at it?

Hello,
This is not a bug!
the & must be escaped in &amp; in a hyperlink, this is the (X)HTML
specification. It was broken in 5.2.4 and corrected in 5.3.1 because
it's the correct behavior.
The remaining bug I know of is when using the href binding with
parameters, it leads to &amp;amp; in code which is incorrect, so it
sort of a double escape.
If you are using formValueForKey it correctly gets every parameters
from the DA URL.

Yes, this was broken in 5.3.1, but apparently fixed in 5.3.1. That
is, it was broken with the 5.3.1 that was introduced with (if I
recall) a Mac OS X Server updated), and may be fixed with the 5.3.1
that was introduced with Xcode 2.3.

(Perhaps Apple has exceeded its version number budget, and so all
future WebObjects releases will also be 5.3.1.)

The workaround is to write a method that calls WOContext's
directActionURLForActionNamed() and manually munge the URL
yourself, e.g., something like:

String url = context().directActionURLForActionNamed
("refreshReminder", getRefreshQueryDictionary());
url = url.replaceAll("&amp;", "&");
return url;

We recently upgraded to 5.3.1 from 5.2.4 and are having problems with
WOActionURL. We use WOActionURL for Ajax and the & is adding the
HTML
escape in 5.3.1 but never did this in 5.2.4. This is causing it
to not
find the session and the URL is then invalid.


Any ideas?  Is this a bug in 5.3.1?

Thanks in advance,
David

5.3.1:
.../wa/org.yfu.ui.announcement.ReminderDA/refreshReminder?
id=46002395450
30766980&amp;wosid=B6fPodDWHmwlDcUs54Uaj0
5.2.4:
.../wa/org.yfu.ui.announcement.ReminderDA/refreshReminder?
id=46002395450
30766980&wosid=B6fPodDWHmwlDcUs54Uaj0


ActionURL1: WOActionURL { actionClass = "org.yfu.ui.announcement.ReminderDA"; directActionName = "refreshReminder"; queryDictionary = refreshQueryDictionary; }

public NSDictionary getRefreshQueryDictionary(){
return new NSDictionary(getReminderIterator().getId(), "id");
}
