html:text - want to set disable= to a bean value
Hi there,
What I'm trying to do is re-use the same jsp for ADD/UPDATE modes. In
order to do this, certain field attributes will be different depending
on the modes and sometimes even on the user's security credentials or
the 'status' of the customer row.
To this end I need to pass in the form bean whether a particular field
is disabled or not
I've searched the archives to no avail. I'm trying to set the disable=''
attribute on the html:text tag to a value in the form bean I'm passing
in.
eg:
formbean.isCustomerCodeEnabled()
returns a boolean true/false
formbean.getCustomerCode()
is the value of customer code.
I'm trying (hoping) to do something like this:
<html:text property="customerCode" maxlength="8"size="8"
disable="!CustomerCodeEnabled" />
I've tried lots of different approaches, all failing. I've also scanned
the examples to no avail.
Latest attempt is:
<bean:define id="customerCodeEnabled"
name="CustomerFormWindowMainTabActionForm"
property="CustomerCodeEnabled"
type="boolean" value="true"/>
<% boolean customerCodeDisabled=(!customerCodeEnabled); %>
<TD><html:text property="customerCode" maxlength="8"size="8"
disabled="<%=customerCodeDisabled%>" /></TD>
Which fails with:
customerCodeEnabled = null; [javac] ^ An error occurred at line: 87 in
the jsp file: /CustomerFormWindowMainTabBody.jsp Generated servlet
error:
[javac]/home/sfg/javadev/jboss-3.2.3/server/default/work/MainEngine/localhost/pimsweb/CustomerFormWindowMainTabBody_jsp.java:175: inconvertible types
[javac] found : java.lang.Object [javac] required: boolean [javac]
customerCodeEnabled = (boolean)
pageContext.findAttribute("customerCodeEnabled"); [javac] ^ [javac] 2

Thanks Rick.
I need to rely on the backend to decide whether to enable/disable as the
requirement is a 'business rule' not an interface decision. Here are the
factors:
- What 'stage' is this row of the table reached determines if this field
can be changed or not.
- What 'security level' the current session's user has determines
enable/disable.
So unfortunately, putting all this in the view would lead to huge
amounts of choosings. I'd rather the view was really dumb and just
reacted to decisions @ the backend.

This looks promising. Thanks for your help..

I usually don't like to have my formBean take care of holding this
information. Not that it's necessarily bad, I just sort of like having
my form beans as dumb as possible and only maintain form captured
information.
What I do in the above is base what to display on a "userAction" which
actually ends up corresponding to my dispatch Action method name. This I
will sometimes add as an ActionForm property (ie String userAction ).
I then control the dispaly based on this userAction ( "update", "add").
You'll end up with a bit more verbose code but I find it easier to
maintain.. so for example....
You might have a case where if you are doing an update you can't update
the User Name but can update other fields:
Name:
<c:choose>
<c:when test="${userFormBean.userAction == 'update'}">
<c:out value="${userFormBean.name}"/>
</c:when>
<c:othewise>
<html:text property="name"/>
</c:otherwise>
</c:choose>
If you really want you can do your approach though but you'll have to
use the html-el tags
Then you can do:
<html-el:text property="customerCode" maxlength="8"size="8"
disable="${userFormBean.customerCodeEnabled}" />
where customerCodeEnabled would correspond to "true" or "false" and be
set accordingly. I don't like this approach though because you'll end up
having to code a bunch of these for different fields and you've made
your backend responsible for figuring out how to display the info on the
page ( he he I say I don't like this, and now I'm on a project where the
whole application is going to be coded by meta-data to tell the front
what to display.. but still in theory I don't like it:)

Does this work for you?
<html:text property="customerCode" maxlength="8" size="8"
disable="isCustomerCodeEnabled" />
I had an app with similar requirements. IIRC, I solved it by doing the
following.
In the JSP first define the FormBean that contains the boolean values:
<bean:define name="SomeForm" id="form"
type="com.myCompany.MyFormBeanClass" />
then access the boolean fields for each form field like so:
<html:text property="description" maxlength="79" size="60" readonly="<%=
form.isDescriptionDisabled() %>" />
Hope that helps.
