Expected: Naming convention or icon corresponding must suggest type"""

descricao2 = """h3. original discussion http://developer.appcelerator.com/question/145992/databinding-on-picker h3. problem Collection binding is not implemented for Ti.UI.Picker as it is for Ti.UI.TableView and other generic Titaniums views (View, Window, ScrollView, etc...). h3. solution Support collection binding on Ti.UI.Picker just as it is on TableView. It will need special handling as the Ti.UI.Picker requires custom parsing for columns and rows. Something like this should be how it would work for devs: {code:xml} <Alloy> <Collection src="book" /> <Window class="container"> <Picker dataCollection="book"> <PickerRow title="{title}" /> </Picker> </Window> </Alloy> {code}"""

titulo4 = """Orphan file cleanup deletes builtins and widget assets"""
descricao4 = """During the compile process Alloy will attempt to remove files from the Resources directory that are no longer present anywhere in the ""app"" folder. Alloy searches a number of locations in the ""app"" folder to see if the file is an orphan or not. False negatives should be avoided as they will leave unused files in the project. False positives on the other hand are not really worrisome since those resources will be recreated on the next compile anyway.     With that in mind, there are currently false positives for orphan file deletion for builtins and widgets. Builtins and widgets will be pulled in fresh each time. Again, this will not negatively impact a developer's build process or app in any way, it would just be more true to the logic if these files were left alone during the orphan cleanup phase."""

titulo5 = """Resolve suboptimal compression from uglify-js v2 update"""
descricao5 = """The v2 update of uglify-js in Alloy, specifically version 2.2.5, has some suboptimal compressions, which are causing the optimizer.js test spec to fail in certain cases. Specifically the issues are around booleans and cascading of variables in assignments. These issues have been logged with the Uglifyjs2 project in the following links:    * https://github.com/mishoo/UglifyJS2/issues/137  * https://github.com/mishoo/UglifyJS2/issues/138    When these issues are resolved and distributed in an npm release, we need to revisit these compressions and testing to ensure that the fixes are in place, and that new uglify-js version has no regressions that impact alloy."""
