>          Key: TAPESTRY-238
>          URL: http://issues.apache.org/jira/browse/TAPESTRY-238
>      Project: Tapestry
>         Type: Bug
>   Components: Contrib
>     Versions: 3.0, 3.0.1
>     Reporter: Jonathan O'Connor
>     Assignee: Paul Ferraro
>      Fix For: 3.0.3

>
> Steps to reproduce:
> 1. Create a page with a DatePicker component.
> 2. Add an onchange JavaScript call to the DatePicker. E.g.
> 			<span jwcid="@DatePicker" value="ognl:dateValue"
> 				onchange="handleDateChanged()">
> 				<input type="text" value="Day Month Year"/>
> 			</span>
> 3. Click on the Calendar control and change the date.
> Result:
> The text field is updated, but the handleDateChanged() method is not called.
> Expected Result:
> The text field is updated, AND the handleDateChanged() method IS called.
> Fix:
> Change the DatePicker.script in framework/src/org.apache/tapestry/form.
> ${calendarObject}.onchange = function() {
>     document.${formName}.${name}.value  = ${calendarObject}.formatDate();
>     document.${formName}.${name}.onchange(); /* New line invokes the onchange method */
> }
> This works on both Firefox and IE 6.0. It also works when there is no onchange method set.
