getting java.util.NoSuchElementException occasionally
Hi All,
I am using MyFaces1.1.5, Tomahawk 1.1.6, ajax4jsf1.1.1 on weblogic 8.1 sp6. Users are sometimes getting NoSuchElementException. Following is the StackTrace of the exception. StackTrace doesn't give any information regarding where in the application is started and hence I am not able to figure out what action might have caused it.
Any help is appreciated.
Thanks in advance,
Nitin

Catch the right-click event and prevent it?

your post really helped me understand the behaviour. So, right click is always going to be an issue. any solution/suggestions for that? because no matter what I do, I can not restrict the users from right clicking and then complaining that link didn't work the way it was supposed to.
For the original issue, if I use conversation scoped bean, I can most probably avoid the situation where two threads are trying to modify the same list/variables at the same time. also, it will allow users to carry out two different actions at the same time.
Thanks,
Nitin

In this situation, if user right clicks on any of the links, the action is not performed and the parameter is not passed. instead it opens the new window in the previous page.
Plain JSF will not execute any actions on a GET http operation; the only
thing it does for a GET is to render the page.
This also happens to be the recommended behaviour for RESTful webapps;
GET is supposed to be an operation that does not change any system state.
I think this is also the cause of your "render the previous page" issue.
When the user clicks normally on the link, what happens is actually a
form postback; this triggers an action method that then performs
navigation to the next page. But when the user right-clicks on the
link, what happens is a GET; this does not trigger any action methods,
so no nagivation to the "next page" takes place. Instead, the current
view gets rendered again.

Simon

ok... it sounds better than what I currently have. two question though - will right click on a commandLink cause the action of the link to be executed, because in current scenario it doesn't? second question - will it pass the parameters in case of right click if I have any?
currently, how I do things is - I have a param in each of the commandLinks and the links point to the same action. on the basis of the param received, I decide the action to be performed and return to a page. In this situation, if user right clicks on any of the links, the action is not performed and the parameter is not passed. instead it opens the new window in the previous page.

In seam, the conversation lives in the form URL as a query string. So
unless you post, then you don't carry the conversation over. For
outputLink, you have to explicitly add the seam conversation ID if you
want it to continue. Only duplicating a tab could cause a problem.

Re: getting java.util.NoSuchElementException occasionally
Posted by Nitin Deshmukh <de...@yahoo.com>.
in my case, when user clicks on the right-click>open in new window/tab, the links open the previous page, as I use command links all over. and since everything is picked up from the session scoped bean, even if user tries to do two different actions, it wouldn't allow that and bring the page on the basis of whatever action was performed last in either of the windows.
what happens when I switch to seam/orchestra and user tries to do the same thing?

Nitin

Well, that only "mostly" works with Orchestra. Everything is ok as long
as the user never uses "right-click>open in new tab", or copies/pastes
the complete url.
I expect that the same limitation applies for Seam's conversation
scopes, though I haven't checked.

You could also use conversation scoped beans (Seam or Orchestra). That
way your beans would be bound to the window and not the session.

Users can open multiple windows, that is possible. But I don't have any automatic ajax requests. I am using ajax on the home page only. But I suppose what you are saying is possible that user is trying to do multiple simultaneous request and that might have caused it.
Also, I do have reports that users also get java.util.ConcurrentModificationException occasionally. I wonder if both the exceptions are because of the same reason.. The second exception arises from the action method of a session scoped bean. so, if two threads are trying to modify the list at the same time, it is possible to get this exception.
In the second case, I think the only option I see is to make my action method synchronized, or at least to synchronize the block where list is being modified.. Is there any other option for me?
and about the first exception, I have no idea where it starts.
Thanks,
Nitin

I wonder if you have the same problem as someone else posting today. Do
your users happen to have multiple windows open at once, in which they
are doing simultaneous requests? Perhaps due to some automatic periodic
ajax request that is configured to execute in each page?

Re: getting java.util.NoSuchElementException occasionally
Posted by Nitin Deshmukh <de...@yahoo.com>.
I do have selectOneMenus, but I have a standard method to populate them and all the data is pulled from the database. so, if there was a wrong value, this exception will occur for lots of users. But it happens once in a while. But I suppose, I can still look into my code and data and see if that is the cause. I will check for the empty list also.
Thanks a lot,
Nitin

Re: getting java.util.NoSuchElementException occasionally

Hi Nitin,
Do you have selectOneMenus or selectOneLists ?
This error happened with me before because the selectItem was empty, and
other times because the selectItem had a wrong value.
Please try to look in your application pages from this perspective.
