This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
How to reproduce: 1) Create JSP file. 2) Type: <1> 3) ERROR - "1" is not marked as invalid.
there is no reason to mark it as an error - such a tag is a common HTML/JSP plain text. The JSP editor behaves in the some way as HTML editor.
