Hi,
I think there is a bug in ComboBox.js of version 0.7.3 (didn't check with
0.8.x) which is triggered when a ComboBox does not have an item selected -
either after setting it up or after calling resetSelected() - and a
changeLocale event occurs. The following code is enough to reproduce the
error:
var testMenu = new qx.ui.form.ComboBox();
var testItem=new qx.ui.form.ListItem('test');
testMenu.add(testItem);
testMenu.addToDocument();
qx.locale.Manager.getInstance().setLocale('de');
whereas the following code does not give an error:
var testMenu = new qx.ui.form.ComboBox();
var testItem=new qx.ui.form.ListItem('test');
testMenu.add(testItem);
testMenu.addToDocument();
testMenu.setSelected(testItem);
qx.locale.Manager.getInstance().setLocale('de');
I think the locale change event tries to change the label string of a none
existing item.
The error message is:
item is null
var label = item.getLabelObject();
on line 1017 in ComboBox.js:
1004 /**
1005 * Return the formatted label text from the <code>ListItem</code>.
1006 * The formatter removes all HTML tags and converts all HTML entities
1007 * to string characters if the <code>ListItem</code> is identified as
1008 * HTML text or the mode is set to <code>"html"</code>.
1009 *
1010 * @type member
1011 * @param item {ListItem} The list item to format.
1012 * @return {String} The formatted text.
1013 */
1014 __defaultFormat : function(item)
1015
1015 {
1016 var valueLabel = item ? item.getLabel().toString() : "";
1017 var label = item.getLabelObject();
1018
1019 if (label != null)
1020 {
I think there should be a check for item!=null protecting the call to
item.getLabelObject() and an appropriate return if no item is selected.
Cheers,
Fritz
