RE: Getting data from a disabled form field
Yep. The browser doesnt submit a value for the field if its disabled. If your using a request scoped actionform then you will either need to reload its value from wherever or add an additional hidden field on the form to submit the value. If its a session scoped form, just make sure that you dont clear it in reset. btw: if this is a security thing then you must make sure that your setters (or something else server side) dont accept different values for these fields when the user hasnt got appropriate rights as a user can easily play silly buggers with the url and script kiddies can easily spoof POST requests - both bypassing any kind of client side validation or 'security'. -Original Message- From: Arne Brutschy [mailto:[EMAIL PROTECTED] Sent: Thursday, 12 February 2004 21:32 To: Struts Users Mailing List Subject: Getting data from a disabled form field Hi, I have a problem with disabled form fields. I'm using a user entry form, which fields can be edited by the current user based on his group memberships. So a normal user without admin status cannot change the uid, as this field is disabled. My problem is, that after submitting the form, validation fails because of the validator which cannot read the uids field context (I assume because it's disabled). Trying to get the form data returns an empty string. Anyone encountered this type of problem? Is there any way around it?

Re: Getting data from a disabled form field
i believe that disabled form elements return null. I hate to say it, but you could have the uid stored as a hidden variable in the case of the non admin user but still display a text field with the value displayed.

RE: Getting data from a disabled form field
Try using Javascript to re-enable the fields when the form is submitted, this allows them to be passed through to the form as normal. -Original Message- From: Mark Lowe [mailto:[EMAIL PROTECTED] Sent: 12 February 2004 13:46 To: Struts Users Mailing List Subject: Re: Getting data from a disabled form field i believe that disabled form elements return null.

RE: Getting data from a disabled form field
They dont submit any parameter in the posted request. As a result, when struts populates the form, iterating the list of request parameters and calling the setters with the values it wont call the setter for that one. The value in the actionform thus depends upon the logic in the forms reset method - and if that field is not reset, upon the pre-existing value in the actionform which will remain unchanged. In the case of a request scoped form, this will of course be a new actionform instance so will give whatever the forms initial value is when the form is created.
