The "name" attribute on the HTML generated by is automatically set to the name of the action that will be receiving the form input, if I'm not mistaken.

Re: Newbie Nested Tag Question
Thanks for the suggestion, late last night I finally found my problem. I needed to
delete the old nested-tags.jar file from my libs folder. When I downloaded the
keyboard monkey tutorial it came with that jar file - but since I am using Struts 1.1
- I don't need it and it actually causes problems. It is such a silly error - but
really hard to track down. Anyways thanks again.

RE: Iterate Tag Question
Matt, Yes it does. I was hoping to get rid of scriplets if possible. I cannot use JSTL yet because our jsp container does not support the jsp 1.2 spec. (Jrun 3.1). We are going to migrate to Jrun 4 soon which supports the jsp 1.2 spec so I will be able to use JSTL then. Guess I will have to use scriplets until then.

Re: [OFF TOPIC] JavaScript + tag question
The line I wrote doesn't reference the value property of the select, it references the value property of the selected option. I could have also written: document.formname.selectelementname.options[document.formname.selectelementname.selectedIndex].value but I saved a couple of bytes since a select has a collection of options you can leave off the .options and just use [i]. document.formname.elementname works in both ie (since 3 or 4) and moz so I use it.

Newbie Nested Tag Question
I am having trouble implementing the nested tags. I have downloaded and completed the
Keyboard Monkey tutorial and everything ran smoothly, but when I try and implement the
tags in my program I am having problems. The following code using the logic tags
works correctly and displays the desired information. The code using the nested tags
results in the Null Pointer Exception that follows. The property names are different,
but refer to the same variable, one returns the information as an ArrayList and the
other as and Object[] as shown below. If anyone has some ideas I would really
appreciate them!!
Thanks,
Lynda

Re: [OFF TOPIC] JavaScript + tag question
I'd write some sort of function and call it from the event.
onchange="submitFromDropdown(this)"
and your function should be something like this:
submitFromDropdown(dropdown)
{
//'this' == dropdown field object
var fieldName = dropdown.name;
var len = dropdown.options.length;
var item = '';
for (i = 0; i < len; i++) {
if (dropdown.options[i].selected)
item = dropdown.options[i].value;
}
var url = "/search.do?action=" + fieldName
+ "&selectedItem=" + item;
dropdown.form.action = url;
dropdown.form.submit();
}
I changed the code from my working code - usual disclaimers apply. You
might need to debug it a little, but that's easy too.

I would like to do the following :
I have a form with different fields and drop down boxes
When A drop down box is selectd I would like to do a submit that looks
more or less like this :
submit=/search.do?action=dropdownbox1&selectedItem=item
I would like to do this because I need the action parameter for my
DispatchAction class and the selectedItem obviously to know what the
selection is.
Is there a way to perform this inside a struts select tags event useing
JavaScriptIf so can you give me an example ( short code snippet
maybe ).
Thanks,
Todor
