It's a good idea to validate your bar-descriptor.xml file to make sure that your app deploys correctly. You can validate the contents of your bar-descriptor.xml file using the following techniques:
The Problems view links to the XML elements in the Source tab. These identifiers are created by a validation builder for BlackBerry projects. You can scroll through the errors, warnings, or information to find problems in your bar-descriptor.xml file. You can also use a filter to show only problems in the bar-descriptor.xml file. To open the Problems view click .
If there are problems in your bar-descriptor.xml file, the General tab displays a warning icon and a tooltip with the number of problems in the Problems area.
Annotations are automatically generated as you edit and change the bar-descriptor.xml file. Incorrect data is annotated in place. For example, an unresolved asset in the Assets tab can result in an annotation of the Assets tab header.
On the Application tab or Localization tab, missing icons or splash screens are highlighted with a warning icon beside the Device Icon Sizes or Device Splash Screen Sizes links. When you click the link, a dialog box shows you which images are missing and which images are incorrectly sized.
