Subject [jira] Created: (TAPESTRY-238) DatePicker not calling onchange on text edit, after setting a new value.

DatePicker not calling onchange on text edit, after setting a new value.
------------------------------------------------------------------------

         Key: TAPESTRY-238
         URL: http://nagoya.apache.org/jira/browse/TAPESTRY-238
     Project: Tapestry
        Type: Bug
  Components: Contrib  
    Versions: 3.0.1, 3.0    
    Reporter: Jonathan O'Connor


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.
