Worked on stabilizing the Product Editor within the eclipse-pde/eclipse.pde repository by addressing a UI regression affecting application selection. Focused on Java-based bug fixing and UI development, the work involved correcting a mouse wheel event binding that previously targeted the wrong control due to a copy-paste error. By ensuring the event listener was attached to the intended combo box, the update prevented unintended changes to the selected application, thereby improving editor reliability. The solution was committed and validated, resolving a bug introduced in an earlier commit and contributing to a more predictable user experience within the Java-based Eclipse PDE environment.
