+
+Issue Report Summary:
+CloseHandler.onClose() doesn't fire when added to PopupPanel
+
+Found in GWT Release (e.g. 1.5.3, 1.6 RC):
+GWT 1.6.2
+
+Encountered on OS / Browser (e.g. WinXP, IE6-7 | Fedora 10, FF3):
+WinXP, IE6-8, Chrome, hosted mode | MacOSX Leopard Safari 3.2.1, hosted
mode
+This is not an issue on WinXP FF3.
+
+
+Detailed description (please be as specific as possible):
+
+If I add a CloseHandler to a PopupPanel, the onClose() method nevers seems
to fire. I've tried adding the same CloseHandler to other widgets like a
MenuBar and it worked fine in all browsers there.
+
+You can reproduce this issue by doing the following:
+
+1) Setup your test application with the repro code snippet below.
+
+2) Start the application in hosted mode and click to put focus on the news
popup widget.
+
+3) With the news popup open, try closing the popup and expect the
onClose() method to fire. You'll notice that on the browsers listed above,
the onKeyUp method isn't being fired.
+
+Repro code snippet (to help us reproduce the issue):
+
+Here is the PopupPanel that I'm trying to add the KeyUpHandler to:
+
+public class NewsPopup extends PopupPanel {
+ private List<Article> articles = new ArrayList<Article>(16);
+ private Article lastArticle = new Article();
+ private Grid articlesGrid = new Grid(4,4);
+ VerticalPanel articlePanel = new VerticalPanel();
+
+ public NewsPopup() {
+ super();
+ int i = 0, j = 0;
+ for(Article article : articles) {
+ if(i == 4) {
+ i = 0;
+ }
+
+ if(j == 4) {
+ j = 0;
+ }
+
+ articlesGrid.setWidget(i, j, article);
+ i++;
+ j++;
+ }
+ }
+
+ /**
+ * Retains the last article that was selected when the news popup is
closed.
+ */
+ public void rememberLastArticle() {
+ // Set last article to the last selected article
+ }
+}
+
+The Article widget is a simple class that wraps a Label indicating the
article title.
+
+Here is the CloseHandler I'm trying to add to the news popup in the entry
point onModuleLoad() method:
+
+final NewsPopup newsPopup = new NewsPopup();
+newsPopup.addCloseHandler(new CloseHandler<PopupPanel>() {
+ @Override
+ public void onClose(CloseEvent<PopupPanel> event) {
+ newsPopup.rememberLastArticle();
+ }
+});
+
+Workaround if you have one:
+
+Maintain state everytime there is a change to the news panel, but this
gets expensive.
