		"description": "{html}<div><p>If you back out of a window while a separate thread (such as a\ncallback from an XHR, which is how we discovered this problem) is\nmaking use of proxy objects (view proxies and such) on that window,\nyou can cause an FC. The FC can occur at multiple places in code,\noften in the form of a <code>NullPointerException</code> when\ntrying to access something that doesn't exist anymore because the\nwindow's context and activity have been released. Here's a sample\nFC:</p>\n<pre>\n<code>E/TiUncaughtHandler(  231): java.lang.NullPointerException\nE/TiUncaughtHandler(  231):     at ti.modules.titanium.ui.TableViewProxy.rowProxyFor(TableViewProxy.java:400)\nE/TiUncaughtHandler(  231):     at ti.modules.titanium.ui.TableViewProxy.handleInsertRowBefore(TableViewProxy.java:240)\nE/TiUncaughtHandler(  231):     at ti.modules.titanium.ui.TableViewProxy.handleMessage(TableViewProxy.java:466)\nE/TiUncaughtHandler(  231):     at android.os.Handler.dispatchMessage(Handler.java:95)\nE/TiUncaughtHandler(  231):     at android.os.Looper.loop(Looper.java:123)\nE/TiUncaughtHandler(  231):     at android.app.ActivityThread.main(ActivityThread.java:4203)\nE/TiUncaughtHandler(  231):     at java.lang.reflect.Method.invokeNative(Native Method)\nE/TiUncaughtHandler(  231):     at java.lang.reflect.Method.invoke(Method.java:521)</code>\n</pre>\n<p>You can cause an FC using this app.js + win.js + table.js:</p>\n<p>app.js:</p>\n<pre>\n<code class=\"javascript\">Titanium.UI.setBackgroundColor('#000');\nTitanium.UI.createWindow({  \n    title:'Test',\n    backgroundColor:'#fff',\n    fullscreen: true,\n    exitOnClose: true,\n    url: 'win.js'\n}).open();</code>\n</pre>\n<p>win.js:</p>\n<pre>\n<code class=\"javascript\">var win = Ti.UI.currentWindow;\nvar btn = Ti.UI.createButton({\n    title: 'Open 2nd Window'\n});\nbtn.addEventListener('click', function(){\n    Ti.UI.createWindow( {\n        fullscreen:true,\n        url: 'table.js',\n        backgroundColor: 'black'\n    }).open();\n});\nwin.add(btn);</code>\n</pre>\n<p>table.js:</p>\n<pre>\n<code class=\"javascript\">var win = Ti.UI.currentWindow;\nvar tv = Ti.UI.createTableView();\ntv.setData( [ Ti.UI.createTableViewRow({ title: 'Loading...' }) ] );\nwin.add(tv);\n\n// Now start a second thread that will update the table\nsetTimeout(function() {\n    for (var i = 1; i &lt;= 1000; i++) {\n        tv.insertRowBefore(0, \n            Ti.UI.createTableViewRow( {title: 'New row ' + i} ));\n    }\n}, 50);</code>\n</pre>\n<p>When you run it and you open the second window, click your\nhardware back button while the table is being assembled.
