Problem Markers
Problem markers are a standard Eclipse feature that track issues associated with workspace resources.
They appear in the Problems view, which can be filtered in various ways, as well as on elements in the Outline view and in the Form Designer. A marker includes a summary of the problem and identifies the affected file and the internal location. It also has a severity level (error, warning, or informational). The marker icons indicate the severity level:
Double-clicking a form validation marker will open or activate the Form Designer and select the offending form element (generally a pane or control). You can then use the Properties view or canvas to fix the problem manually.
Quick Fixes
Some of the problems detected by the Validation Builder can be corrected automatically by applying a Quick Fix. If a Quick Fix is available, the corresponding action on the problem marker’s Context Menu is enabled.
With the Quick Fix dialog, you can select the fix to apply (there may be more than one), and also select other instances of the same problem in order to fix them all at once. You can do this only for non-interactive quick fixes.
