use this code in JSP file: -------------------- <jsp:element name=""> <jsp:attribute /> </jsp:element> -------------------- attribute tag is missing "name" attribute ->error annotation is show.. OK move cursor at position of marked line press Alt+Enter -> the error message should be shown, but nothing happens; text is shown only as a tooltip after putting mouse over the text Note: see behavior of CSS or java annotations h1 { azimuth: rightward; }
This is because of the JSP error annotations are proprietary implemented and doesn't use the hints api at all. Changing to enhancement.
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
