Hello,

Sometimes we got a warning from PageRendererBase class while calling an
action. In contrast to firefox, internet explorer don`t produce this
warning.
I found out, that by decoding the requested page the request parametr
"actionPositionString" contains negative pixel values. 
I don`t know what that means and why.

Log:
WARN org.apache.myfaces.tobago.renderkit.PageRendererBase - Can't
analyse parameter for action-position
java.lang.IllegalArgumentException: Can't parse to any measure: '-12px' 
at org.apache.myfaces.tobago.layout.Measure.parse(Measure.java:39) 
at org.apache.myfaces.tobago.layout.Position.<init>(Position.java:38) 
at org.apache.myfaces.tobago.layout.Box.<init>(Box.java:40) at 

Env:
Tabago Version: 1.0.30
MyFaces: 1.1.7
FireFox: 4.0.1
IE: 6.0


Regards,
Hani
