Action Form:
LabelValueBean[] options = new LabelValueBean[31];

public LabelValueBean[] getOptions()
{
for (int i = 1; i <= 31; i++) {
options[i] = new LabelValueBean("Show topics for last " + String.valueOf(i) + " day", String.valueOf(i));

The phrase "doesn't work" doesn't tell me anything useful. Please post the error message you're getting along with the stack trace if there is one. Also post the relevant portions of your JSP including the <html:form> tag, as well as relevant portions of your struts-config.xml file

One thing to check is to make sure that this Actionform is tied to the action specified in the <html:form> tag.

Hi,
There is no ActionForm associated with the Action Class. Hence i am storing the options attribute in the request attribute.

Action Class:
-------------

request.setAttribute("options",sysEventsFormObj.getOptions());

Action Form:
------------
LabelValueBean[] options = new LabelValueBean[32];

public LabelValueBean[] getOptions()
{
for (int i = 1; i <= 31; i++) {
options[i] = new LabelValueBean("Show events for last " + String.valueOf(i) + " day", String.valueOf(i));
}
return options;
}

I would like to retrive the options attribute in the <html

ptionCollection> tag with out using the form bean obj. Any help is appreciated on this.

regards
sudha

Sorry, but you can't do that. An <html:optionsCollection> tag must be inside an <html:form> tag which must point to an action that has an Actionform bean associated with it. There's no getting around this requirement.

Hi,

If you don't want to use form bean object. You can create a hidden field and a js function. The js function will be called when you change the options in the dropdown.This js function will do two tasks.

1. Set the hidden field value to the selected value
2. submit the form.
3. get the value in the action using request.getParameter

Will this help to meet your requirement?

Thanks,
Vivek
