Description Gerry Kessler CLA 2008-03-06 14:45:19 EST 
Using I20080305091544

After creating a simple jsp page with a couple of JSF HTML tags in a new project and workspace and then validating, the page yielded 2 identical errors in the log.   This may be a first time only thing.   I was not able to reproduce this again, even after restarting the workspace.  The JSF validation ran successfully.

Comment 1 Gerry Kessler CLA 2008-03-06 15:55:04 EST 
Found the steps to reproduce:

0) display error log view
1) create JSP page and drop commandButton
2) in source pane, start typing "value" attribute

Note will get error log entry for every keystroke if you type slow enough
