带有XDebug的Aptana Studio：在断点处打开了错误的文件

I'm using Aptana Studio 1.2.7 with XDebug 2.0.4 and my website is based on the zend framework. When reaching a breakpoint in my code, aptana studio opens the wrong file when there is more than one file with the same name (e.g. ..\library\Project\Db\Table\Abstract.php (breakpoint set) and \library\Zend\View\Helper\Placeholfer\Container\Abstract.php). The variables are shown correctly and the correct line is highlighted, the wrong file is shown. Is there any solution to this problem?I'm using Aptana Studio 1.2.7 with XDebug 2.0.4
