Description

The combination of using the Android Holo theme with a TabGroup and using Ti.Android.ActionBar.displayHomeAsUp in a second Window opened in one of the Tabs randomly results in a double ActionBar like shown in the attached screenshot. As the XML layout next to the screenshot shows there are actually 2 Windows present, each with its own ActionBar. Removing lines 12-14 from the app.js code below and the problem is gone, showing the cause lies in the displayHomeAsUp logic.

Steps to reproduce

1. Generate a new empty project 2. Replace the <android> tag in tiapp.xml with:

    <android xmlns:android="http://schemas.android.com/apk/res/android"> 
        <tool-api-level>14</tool-api-level> 
        <manifest> 
            <uses-sdk android:targetSdkVersion="11"/> 
            <application android:theme="@android:style/Theme.Holo.Light"/>
        </manifest> 
    </android>

3. Replace the contents of app.js with:

var tabGroup = Ti.UI.createTabGroup({
    backgroundColor: "white"
});
var win1 = Ti.UI.createWindow({
    title: "Window 1",
    backgroundColor: "green"
});
win1.addEventListener('click', function () {
    var win2 = Ti.UI.createWindow({
        backgroundColor: 'red'
    });
    win2.addEventListener('open', function () {
        win2.activity.actionBar.setDisplayHomeAsUp(true);
    });
    tab1.open(win2);
});
var tab1 = Ti.UI.createTab({
    window: win1,
    title: "Tab 1"
});
tabGroup.addTab(tab1);
tabGroup.open();

4. Repeatedly tap the green window to open the red window and use the hardware back button to return. Every now and then you should see the described behavior.

I am getting this error randomly on my apps, it shows every other time or so, there is no telling when it will occur.

Is this now fixed with TIMOB-14914?
