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 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:)
