Haiwei,
Would the <bean:define> tag meet your needs? The value is available for
use when building the page, but I don't believe that it is in the form
dataset.
Alternatively, you might consider extending the hidden tag for your needs.
Once it works, you could submit the code as a candidate for changing the
hidden tag in a future release.

Please respond to
"Struts Users
Mailing List"
Rober,
<bean:write> tag allows to retrieve the value of the specified bean
property
and render it to the page as a String.
<html:hidden> tag and the resulting hidden field do more than what
<bean:write> does. The value of the hidden field can be read/manipulated,
and posted back to server. With the disabled attribute (to be added in the
taglib implementation), the <html:hidden> tag provides consistent handling
for dynamic situations.
Thanks.

Dear Haiwei,
>but sometime we want the hidden tag to be disabled so its value will
not be posted to the server.
What is then the purpose of have the hidden tag in it? You could also leave
it out.
You can always access a property using the <bean:write> tag.
Kind regards,
Robert

Thanks for your response. We have a need to include a hidden tag in the
form; but sometime we want the hidden tag to be disabled so its value will
not be posted to the server.
I have filed a bug report. The problem will be fixed in the future Struts
releases.

Haiwei,
The purpose of the hidden tag is to keep the property and its value in the
dataset of the form. And you will use it, when you don't want to expose the
value to the user.
Whereas the disabled attribute will exclude the property from the dataset
in
the request.
For your information. When you would have a unique value for the item
presented on the screen and you use <html:text disabled="true" .... >, then
you will find out
that the property for this unique value is not in your request. With the
normal getters and setters, your unique value now gets blanked. "". And
gone
is your unique code.
Hence, the hidden tag and the disabled attribute are more or less mutually
exclusive.
Kind regards,
Robert Lamping

Does anyone know whether future Struts release will support the "disabled"
attribute for the <html:hidden> tag?
For some reason, it is not supported in the Struts 1.1. Does anyone know
the
reason behind that?
Thanks.
Haiwei
