Conditionally disable form input.

["Daffin, Miles (Company IT)" <Mi...@morganstanley.com>]

Hi All,
 
I want to disable a text input if a certain checkbox input has been
checked (meaning, in the following example, that the name input need not
be filled in). My jsp code looks like this:
 
<html:text
    property="<%=Keys.APPLICANT_FULLNAME_CHINESE%>"
    size="100"
 
disabled='<%=anExpressionThatDeterminesIfTheCheckboxHasBeenChecked()%>'/
>

I an using a DynaActionForm as my form bean. Ideally I suppose I would
use an expression like:
 
formBean.get(otherFieldName) != null
 
Has anyone done something like this?
 
Many thanks.
