Re: bean missing after validation

[Erik Weber]

First I would ask, why aren't you using the Struts tags (such as 
html:hidden)? I assume that you are using them to render your other 
inputs (such as those of type "text").

But, to answer your question, it's a matter of scope. When the page 
containing the form is first rendered, the hidden variable is set to 
some value that lives in request scope. When the form is submitted (and 
validation errors occur), a new request exists, the original request no 
longer exists, and so that value is no longer in scope when the page is 
rendered for the second time.

See if this helps:

hi
i have the following codes in my JSP :
<input type="hidden" name="userID" value="<bean:write name="user"
property="userID" scope="request"/>"/>
which converts into <input type="hidden" name="userID" value="1"/>.
If validation is used and there are errors, the input page is displayed.
Now the above value became :
<input type="hidden" name="userID" value=""/>
The valus is missing..
Can anyone explain why this is happening and how to resolve it?
