Problem in populating html controls from Bean...
HI all,
I want to populate html :text from someBean (request scope)
and also want to associate that html:text with FormBean.
My jsp page is like this
<jsp:useBean id="someBean"
scope="request"
type="SomeBean" />
<html:form action="/DisplayGraphStep2">
Title :
<html:text property="title" value="<bean:write name="someBean"
property ="oldTitle"/>" > </html:text >
</html:form>
I am getting an excepiton for this code.
I want to popoulate the text box with the value of '
someBean.oldTitle ' and also want to associate text box with '
ormBeans.title '.
Can anybody help me....
Thanks & Regards
Swapnil

Good point. I really *must* try and remember that everyone else does it
this way ;-) [that's the problem with using non-standard design patterns!]

Yes exactly.
And if you are going to hardcode the value in there then you might as
well not even use the Struts html tags?
<html:text property="title" value="${someBean.oldTitle}>
Could just become
<input type="text" name="title" value="${someBean.oldTitle}"/>
Occasionaly I will set a value manually in my JSP but for the most part,
as Wendy states, this is usually a very bad practice Swapnil (form bean
properties should be in place before going to the JSP).

That prevents the framework from re-displaying the user's input if the form
fails
validation.
At the risk of repeating myself: the place to pre-populate your form beans
is in the Action, before you forward to the JSP.

This really should be an FAQ :-) The problem is that it's not legal to nest
JSP tags that way. Try:
<html:text property="title" value="${someBean.oldTitle}>
or
<html:text property="title" value="<%= someBean.getOldTitle() %>">
