** For more information see https://bugzilla.mozilla.org/show_bug.cgi?id=187435+ Flash Movies appear on top of Overlay instances ----------------------------------------------- Flash movies can appear on top of Overlay instances in IE and Gecko-based browsers. To fix this problem, set the "wmode" of the Flash movie to either "transparent" or "opaque" as indicated below: Via the <object> tag: <object> <param name="wmode" value="opaque"> </object> <object> <param name="wmode" value="transparent"> </object> Via the <embed> tag: <embed wmode="transparent"> ... </embed> <embed wmode="opaque"> ... </embed> ** For more information see http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_15523+ Overlay instances not rendered at correct z-index in IE ------------------------------------------------------- In IE, when an Overlay instance is rendered inside a relatively positioned element the z-index of the Overlay instance is now relative to its relatively positioned parent element. This is not a bug in the Overlay class, but rather a bug in IE where relatively positioned elements establish a new stacking context for their child nodes. To avoid this bug it is recommend that all Overlay instances that need to be able to float above any other element in the document be made direct descendants of the <body> element. ** For more information see http://therealcrisp.xs4all.nl/meuk/IE-zindexbug.html+ Header elements for Panel instances using "Sam" skin shrinkwrap in IE 7 ----------------------------------------------------------------------- In IE 7 (Standards Mode) if a Panel instance is created without specifying a value for the "width" configuration property the width of the Panel's header element will shrinkwrap to the width of its text node. To avoid triggering this bug in IE always specify a value for the "width" configuration property when using Panel.+ Panel instances render at 100% of the browser viewport ------------------------------------------------------ In IE 7 (Quirks Mode) and IE 6 (Quirks Mode and Standards Mode) if any of the child nodes of a Panel instance's root element have "layout" (http://msdn2.microsoft.com/en-us/library/ms533776.aspx) and no value has been specified for the "width" configuration property, the Panel will render at 100% of the width of browser's viewport. This bug will manifest when using the "Sam" skin as layout is applied to the header, body and footer elements (by setting the CSS "zoom" property of the element to "1" ) in order to get the negative margins required for the rounded corners to render correctly. To avoid triggering this bug in IE always specify a value for the "width" configuration property when using Panel.+ Panel instances render at 2px wider when using "Sam" skin --------------------------------------------------------- For the "Sam" skin a Panel instance's rounded corners are created via the application of negative 1px left and right margins on the header, body and footer elements. These negative margins will cause a Panel instance to be rendered at 2px wider than the value specified by the "width" configuration property. Therefore, when using the "Sam" skin consider the negative left and right margins and subtract 2 from the value passed to the "width" configuration property in order to have the Panel render at the desired width. For example, to render a Panel 300px wide, pass a value of "298px" to the "width" configuration property.*** version 2.2.2 ***+ Clicking the close button of a Panel (or any instance of a Panel subclass) registered with an OverlayManager will no longer result in the Panel receiving focus.+ Overlay instances registered with an OverlayManager will now correctly blur themselves when hidden.+ Calling the "destroy" method of an Overlay instance will now result in it being removed from its OverlayManager instance(s).+ The DOM event listener for the event defined by the "focusevent" configuration property of an OverlayManager instance is now removed from each Overlay instance when it is removed from its OverlayManager.+ All subscribers for an Overlay instance's "focus" and "blur" events are now unsubscribed when it is removed from its OverlayManager.*** version 2.2.1 ***+ Made the default scope for all Custom Events published by Module, Overlay, Panel, Tooltip, Dialog and SimpleDialog the widget instance. Previously the default scope for Custom Events was inconsistent across classes; the default scope for Custom Events published by Overlay was always the Overlay instance whereas the Custom Events published by all of the other classes had no default scope. + Added default scope for CustomEvents published by YAHOO.util.Config: - Default scope for the "configChangedEvent" is now the Config instance. - Default scope for Config property events is now the Config's owner (widget).+ Panel and Tooltip now always convert the value of a DOM element's "tagName" property to uppercase before evaluating it. This improves XHTML compatibility. + Pressing the enter key while focused on a form field inside a Dialog will now trigger the "click" event handler defined by the Dialog's default button in IE and Firefox. Previously, this behavior only worked in Safari and Opera.+ Added a "yui" prefix to the default CSS class name for Module to be consistent with the other Container family widgets.+ Container/Panel's underlay shadow is now defined as partially-transparent black rather than gray. This prevents the shadow from lightening the background color of elements beneath it.+ Fixed memory leaks in Panel and Dialog.+ The Drag and Drop library is now a truly optional dependency for Panel and its subclasses.+ Panel "focus" and "blur" events are now fired when Panels are focused and blurred via the "focus" and "blurAll" methods of YAHOO.widget.OverlayManager.+ Panel instances rendered without setting the value for the "width" configuration property will now have their "width" configuration property set to the value of the Panel's element's "offsetWidth" property when rendered. This fixes an issue in IE 6 and 7 where Panels that are rendered without setting the "width" configuration property will only be draggable by mousing down on the text inside the header, rather than anywhere inside the header. + Refactored the Container family including the Config class to improve performance, especially when working with a large number of instances in IE6.*** version 2.2.0 *** Module - Removed hardcoded file paths for image roots. Affected properties include: - YAHOO.widget.Module.IMG_ROOT - YAHOO.widget.Module.IMG_ROOT_SSL - HTML elements, created via createElement, now use lowercase. Panel - To shield against CSS class collision, the following references now have a "yui-" prefix: - YAHOO.widget.Panel.CSS_PANEL now references CSS class "yui- panel". - YAHOO.widget.Panel.CSS_PANEL_CONTAINER now references CSS class "yui-panel-container". - Close button can now be configured via the CSS class "container- close". - HTML elements, created via createElement, now use lowercase. Dialog - To shield against CSS class collision, the following references now have a "yui-" prefix: - YAHOO.widget.Dialog.CSS_DIALOG now references CSS class "yui- dialog". - HTML elements, created via createElement, now use lowercase. SimpleDialog - Removed hardcoded file paths for SimpleDialog icons, which are now configurable in CSS: - YAHOO.widget.SimpleDialog.ICON_BLOCK now references CSS class "blckicon". - YAHOO.widget.SimpleDialog.ICON_ALARM now references CSS class "alrticon". - YAHOO.widget.SimpleDialog.ICON_HELP now references CSS class "hlpicon". - YAHOO.widget.SimpleDialog.ICON_INFO now references CSS class "infoicon". - YAHOO.widget.SimpleDialog.ICON_WARN now references CSS class "warnicon". - YAHOO.widget.SimpleDialog.ICON_TIP now references CSS class "tipicon". - To provide shield against CSS class collision the following references now have a "yui-" prefix: - YAHOO.widget.SimpleDialog.CSS_SIMPLEDIALOG now references CSS class "yui-simple-dialog"; Tooltip - To shield against CSS class collision, the following references now have a "yui-" prefix: - YAHOO.widget.Tooltip.CSS_TOOLTIP now references CSS class "yui- tipicon" "yui-tt";*** version 0.12.2 *** Module -

Unified scroll/resize handlers so that they fire properly (when the event has completed) as opposed to constantly (as seen in Mozilla- based browsers) Panel - Modified modality mask to show before Panel is shown (prior to any animation) - Modified buildWrapper to eliminate cloning of the initial markup module, which fixes issues with select options not maintaining their default selections in IE - Modality mask is now z-indexed properly so that the mask z-index is always one less than the Panel z-index Dialog - Fixed Connection to get "action" attribute using getAttribute, to allow for form fields named "action" - Added support for "GET" by retrieving the form "method" rather than always defaulting to "POST" KeyListener -
