Re: NPE in AbstractSingleSelectChoice
Improved to not fail with NPE with https://issues.apache.org/jira/browse/WICKET-5601 I think Wicket should warn you somehow when the returned idValue is null though.

Re: Errors in data view , req for help to fix the error in code
Hi,
Please use some pastebin service with code highlighting next time. It is
hard to follow it in a mail client.
The problem is that you try to add a component (the DataView) on the fly
when the form is submitted.
You should add the dataview to the page or form when they are constructed
and just populate its IDataProvider with data in onSubmit();
I.e. initially the DataView will render empty (invisible for the user) and
will show itself after submit because it will have entries to show.

IModel-based multiple-selection DataTable
Hello, I'm trying to roll my own paginated multiple-selection datatable and I'm not sure how to store the selected entities. Many of the solutions I have found online simply add/remove selected entities to/from a SetMyEntity located in the parent component however my DataProviders use LoadableDetachableModels. I could always store them in a Set of IModels but then I'd have to load everything for comparisons. I'm currently digging around in the sources for DataTable and I'm thinking that maybe I would have to provide a custom Item id generation based on the persistent entities' ids and use that to determine whether an item is selected or not but I'm not too sure about this approach (and would also make this solution un-generic)... Has anyone else tried something along these lines? Many Thanks, Anthony -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/IModel-based-multiple-selection-DataTable-tp4666043.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
RE: Ajax timer not counting when tab doesn't have focus?
For anyone interested, and particularly for Ernesto, I have successfully created a version of the InactivityTimeOutPanel that works even if the user changes to another browser tab. The key, which I became aware of from the jsfiddle links (see previous posts below is to use an absolute time for when a period of inactivity would result in a timeout (timeoutTime,set to now plus an interval,, say 5 minutes), and then when the timer fires, to compare the current time against the timeoutTime. This seems to avoid the problem of the timer slowing down when the user changes to another page. Reset just resets the timeoutTime to a now plus the interval. I have set the timer to go off in one quarter of the interval, thinking if there are some delays this will keep it closer to the mark. I have tested this and it seems to work fine. I only had to change the JavaScript in Ernesto's example to get everything to work, and I have posted the code here: http://pastebin.com/TWwS5hhE for people to see. Ernesto, It would be great if you could put this code into the JavaScript in your example and try it out. Then we would have a complete example to point people to if it works OK.

Bruce. Let me see if I can find some time during weekend to play a bit with the links your provided and come up with a more robust solution.

I hope the message come in the right sequence. Lke Ernesto and other A saw the sequencing problem cause by the apache server problem. I ran the test that Martin suggestion with 6.16.0-SNAPSHOTand got the same behavior, which is what Ernesto and I suspected would happen. I'm sorry, but I don't know a lot about JavaScript so I'm having with certain things. I read this article in stackoverflow: https://stackoverflow.com/questions/6032429/chrome-timeouts-interval-s uspended-in-background-tabs Which lead to this: http://stackoverflow.com/questions/5927284/how-can-i-make-setinterval- also-work-when-a-tab-is-inactive-in-chrome Which contained an example of a script that doesn’t work correctly (if you go to it, you will see that it walks the word test across the screen. If you go to another tab and come back test hasn’t moved) http://jsfiddle.net/7f6DX/3/ and this example that works (does the same thing but you can see that test moves even when you go to another tab - but don't go away too long it will reach the end and disappear). http://jsfiddle.net/7f6DX/31/ Do you think the last (working) script could be adapted for our timeout?

Martin, Thanks for pointing out this. The exact JavaScript enabling this feature can be found here https://github.com/reiern70/antilia-bits/blob/master/client-sign-out-p arent/client-sign-out/src/main/java/com/antilia/signout/InactivitySign OutPanel.js Maybe there is a memory leak in here as well... but I do not see the relation with WICKET-5570 as I do not use any of the AJAX timer behavior, see https://github.com/reiern70/antilia-bits/blob/master/client-sign-out-p arent/client-sign-out/src/main/java/com/antilia/signout/InactivitySign OutPanel.java As Bruce describes the problem it sounds like if by switching to other tab browser give less priority to the execution of JavaScript in inactive tabs.

Yes, I do mean another browser tab. I have some new information. The timer seems to slow way down, but not stop counting down when the user switches focus to another tab, either opening a new tab, or just clicking on another tab. This is happening in both Chrome and Firefox. I thought that my code was never timing out, but further experimentation with a shorter timeout period shows that it is doing the same thing as the demo. That is, timing out in about 10 second when you stay on the tab, but taking 3 minutes or longer to timeout when if you change focus to a different tab. I would appreciate it if you could look at
