Okay, so I have an issue that I have finally narrowed down to multi-threading issues.
I have a loader page that has a worker thread to process a csv file and store the results into a list declared as: List batchLines = Collections.synchronizedList(new CopyOnWriteArrayList<BatchLine>()); Each BatchLine object is a row in the csv file that was processed. I also have a pageableListView on the page that uses the BatchLine List to update itself. I use a AjaxSelfUpdatingTimerBehavior which will update the pageableListView every two seconds. The problem is, if I am on this page in one browser tab, and the workerthread is running, and the page is updating, and then at the same time I open another instance of the application in another tab of the same browser, the thread loses focus of this List. I know this because I print out the size of the list, and it stays the same when I open a new instance. I first had the List batchLines Global, but now I pass it as a parameter to keep it local to each method. When it was global, I had to mark it transient for serializable issues. The issue with this is the page would crash when I opened a new tab with another instance of the application. What can I do to prevent this? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Issue-on-multi-threaded-page-when-opening-another-tab-in-browser-tp4664552.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
