Re: Easy form populate question for gurus
Well, I finally figured out a solution to this problem outlined below. Thought
I would share it with the group in case someone else runs into this same
problem.
The problem is somewhere between the Jakarta Commons BeanUtils in conjunction with a
LazyValidatorForm. Since the LazyValidatorForm class is all about being lazy (like
me) where you don't have to define your fields unless they're associated with custom
classes, there is a problem when you go to initialize the form with database data
that contains null values. I thought that since my value object had the fields
defined as java.lang.String objects that they would be translated to that in the form
object when using BeanUtils.copyProperties(...), but that's not always the case. I
had to actually use a element in the LazyValidatorForm
definition in the struts config file defining that the field is a String field. This
defeats the whole purpose for me using the LazyValidatorForm method in the first
place.
Anyway, it fixed my problem, and it appears that I have to stop being lazy. ;-(

The values in question are java.lang.String objects. Should be basic
stuff right? I stepped through the debugger, and the
LazyValidatorForm object is being set correctly for the null strings
from my VO; however, when it comes to displaying the form for editing,
the "null" fields contain an object reference like
[EMAIL PROTECTED] If I update the form with any type of text
values, it'll show correctly the next time that I go to update the
data. It's only happening when there are null values involved.

Re: LookupDispatchAction - missing resource in key method map
OkayI figured out what I was doing wrong, so I'm going to post this
FYI out there just in case someone else makes the same mistake I did.
In my form, I had a hidden field with the same name as the parameter
(e.g. methodToCall) defined in my action. After my initialization
action forwarded to the page, the hidden field was set with the
parameter value I was passing in (e.g. methodToCall=addMemory).
When I clicked on the add button (button.respondent.add.memory), the
"addMemory" value was passed to the LookupDispatchAction as the key to
find the method to call instead of "button.respondent.add.memory".
Hope this explanation makes sense. I figured it out once I downloaded
the code and stepped through the code debug mode.

Here's the message that I receive:

Here is the excerpt from Application.resources:

button.respondent.add.memory = continue to protective order

Here is the excerpt from struts-config.xml:

---
My RespondentFormAction class extends the LookupDispatchAction class
and has the addMemory method:
---
public ActionForward addMemory(ActionMapping mapping, ActionForm
form, HttpServletRequest request, HttpServletResponse response) throws
Exception { ... }
---
I also populate the map as such:
---
protected Map getKeyMethodMap() {
Map map = new HashMap();
map.put("button.pp.add", "add");
map.put("button.respondent.add.memory", "addMemory");
return map;
}
---
Funny thing is is that I have other LookupDispatchActions working
correctly in other places. I don't know what I'm overlooking and
doing differently with this one.
Any suggestions?

Any way to retrieve the index of html:select?
I was wondering if there is any way to retrieve the selection index of the during the action. The value that I'm storing is the coded value for the description that it represents (e.g. 1 for male, 2 for female). Instead of taking the value and hitting the database, I would like to take the selection index and use that to pull the information out of a List that is stored as a session variable. -- Randy Kennedy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Setting focus on invalid form submission
Relatively new to the list, so I apologize if this has already been submitted. I am wondering if there is a way to set the focus after a form has been validated through Struts and deemed invalid? Currently, focus always goes to the first form element. Is there not a way to make this go to the first INVALID form element? Thanks for any help. -- Randy Kennedy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
