Description

I am using a tabview controller to display my contents in tabbed format to the user when he visits a page, but unfortunately its not producing expected output because of some CSS conflicts i believe.

Have attached images to depict the exact happening. One image which shows the normal behavior of my tabview controller, whereas deco breaking the display.

FYI : the functionality part works fine.

Steps to reproduce :

1. Create a page with some title and menu string
2. And paste the below code in the content area

<style type="text/css">
/*margin and padding on body element
  can introduce errors in determining
  element position and are not recommended;
  we turn them off as a foundation for YUI
  CSS treatments. */
body {
margin:0;
padding:0;
}
</style>

<link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.8.0r4/build/fonts/fonts-min.css" />
<link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.8.0r4/build/tabview/assets/skins/sam/tabview.css" />
<script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/yahoo-dom-event/yahoo-dom-event.js"></script>

<script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/history/history-min.js"></script>
</head>

<body class="yui-skin-sam">
<style>

#yui-history-iframe {
  position:absolute;
  top:0; left:0;
  width:1px; height:1px; /* avoid scrollbars */
  visibility:hidden;
}

#demo { margin-bottom:1em; }

</style>

<iframe id="yui-history-iframe" src="assets/blank.html"></iframe>

<input id="yui-history-field" type="hidden">

<div id="demo" class="yui-navset yui-navset-top">
  <ul class="yui-nav">
    <li><a href="#tab1"> <em>Tab One Label</em></a></li>
    <li title="active" class="selected"><a href="#tab2"><em>Tab Two Label</em></a></li>
    <li title="" class=""><a href="#tab3"><em>Tab Three Label</em></a></li>
  </ul>

  <div class="yui-content">
    <div id="tab1"><p>True online double conversion UPS <br />Galvanized isolation <br />Capacity  1 kVA — 160 kVA</p></div>
    <div id="tab2"><p>1 kVA — 36 V
2 kVA — 96 V
3 kVA — 96 V
10 kVA / 20 kVA — 240 V
</p></div>
    <div id="tab3"><p>1 KVA to 1000 KVA. </p></div>
  </div>
</div>

<script>

(function () {

    // The initially selected tab will be chosen in the following order:
    //
    // URL fragment identifier (it will be there if the user previously
    // bookmarked the application in a specific state)
    //
    //         or
    //
    // "tab0" (default)

    var bookmarkedTabViewState = YAHOO.util.History.getBookmarkedState("tabview");
    var initialTabViewState = bookmarkedTabViewState || "tab0";

    var tabView;

    // Register our TabView module. Module registration MUST
    // take place before calling YAHOO.util.History.initialize.
    YAHOO.util.History.register("tabview", initialTabViewState, function (state) {
        // This is called after calling YAHOO.util.History.navigate, or after the user
        // has trigerred the back/forward button. We cannot discrminate between
        // these two situations.

        // "state" can be "tab0", "tab1" or "tab2".
        // Select the right tab:
        tabView.set("activeIndex", state.substr(3));
    });

    function handleTabViewActiveTabChange (e) {
        var newState, currentState;

        newState = "tab" + this.getTabIndex(e.newValue);

        try {
            currentState = YAHOO.util.History.getCurrentState("tabview");
            // The following test is crucial. Otherwise, we end up circling forever.
            // Indeed, YAHOO.util.History.navigate will call the module onStateChange
            // callback, which will call tabView.set, which will call this handler
            // and it keeps going from here...
            if (newState != currentState) {
                YAHOO.util.History.navigate("tabview", newState);
            }
        } catch (e) {
            tabView.set("activeIndex", newState.substr(3));
        }
    }

    function initTabView () {
        // Instantiate the TabView control...
        tabView = new YAHOO.widget.TabView("demo");
        tabView.addListener("activeTabChange", handleTabViewActiveTabChange);
    }

    // Use the Browser History Manager onReady method to instantiate the TabView widget.
    YAHOO.util.History.onReady(function () {
        var currentState;

        initTabView();

        // This is the tricky part... The onLoad event is fired when the user
        // comes back to the page using the back button. In this case, the
        // actual tab that needs to be selected corresponds to the last tab
        // selected before leaving the page, and not the initially selected tab.
        // This can be retrieved using getCurrentState:
        currentState = YAHOO.util.History.getCurrentState("tabview");
        tabView.set("activeIndex", currentState.substr(3));
    });

    // Initialize the browser history management library.
    try {
        YAHOO.util.History.initialize("yui-history-field", "yui-history-iframe");
    } catch (e) {
        // The only exception that gets thrown here is when the browser is
        // not supported (Opera, or not A-grade) Degrade gracefully.
        initTabView();
    }

})();
