why NumberFormatException on Hidden String?

[Tore Halset <ha...@pvv.ntnu.no>]

Hello

I switched from TextField to Hidden and get a NumberFormatException. There
is some javascript that set a string to the field. The field is a String
in the java code as well.

Before (everything works):
<span jwcid="altcmd@TextField" value="ognl:altcmd"/>
After (NumberFormatException):
<span jwcid="altcmd@Hidden" value="ognl:altcmd"/>

Nothing changed in javacode.

The error occurs when my javascrip set the hidden field to "dynzoom"
and submit the form. What can be wrong?

The error:
For input string: "ynzoom"

I am only using one of them at a time. I used the TextField, but tried 
to switch to Hidden.

I'm totally new to Tapestry, but:
Maybe you cannot use the same id for 2 different components?
Try with <span jwcid="altcmd2@Hidden" value="ognl:altcmd"/>
