No, this is not JSF and my question is not related to validation. When I click to edit a JSP page, I see a split screen with a visual preview of the page in the top pane and the actual JSP code in the bottom pane. The more complex the JSP, the longer it takes to render the top preview pane; so I would like a method to disable the preview and only see the JSP code in an edit window. Is this possible with MyEclipse or do I need to go back to Eclipse/WST ?
