dateTimePicker w/o field value shows NAN on the Calendar

[Fletcher Munson]

I'm using Struts 2.1.6 and I have my sx:dateTimePicker working for the most part, but I'm running into an issue when the user removes the date in the field. It changes everything in the calendar dropdown to NAN (except for the month which is changed to 'undefined'). Is there a work around for this?

Thanks,

Fletch

I found if I add a startDate and endDate attribute this issue goes away. Though the calendar then defaults the the startDate, which in my case is about 21 years ago and not likely to be used. Does anyone have any suggestions on how to default this calendar to a preset date without any value in the field?

Hi Guys ,
I too googled for many hours for this and didnt find any solution, so i tried to do it myself and it worked out luckly

In my case i hve this datetimepicker in a TD
--------------------------------------------
<td onkeydown="Javascript:disablekeys();" onmousedown="Javascript:disableControls()">
<sx:datetimepicker id="startDate" name="startDate"></sx:datetimepicker>
</td>
--------------------------------------------

This is the outerHTML of the datetimepicker when it renders
-----------------------------------------------------------
This is document.getElementById('startDate').outerHTML;
<SPAN id=startDate>
<input type=hidden value=2009-06-11 name="" dojoAttachPoint="valueNode">
<input value=6/11/2009 name="" __doClobber__="true" dojoAttachPoint="inputNode">
<img alt="Select a date" src="../images/dateIcon.gif" __doClobber__="true" dojoAttachPoint="buttonNode" dojoAttachEvent="onclick:onIconClick">
---------------------------------------------------------------

So the solution i found out is
------------------------------
<script languae="javascript">
function disableControls(){
document.getElementById('startDate').childNodes[1].disable='true';
document.getElementById('startDate').childNodes[1].readOnly='readonly';
document.getElementById('startDate').childNodes[1].disable='';
}
function disableKeys(){
var keyCode=(document.all)?event.keyCode:e.which;
if(keyCode==9){
window.event.returnValue=true;
}else{
window.event.returnValue=false;
}
}
</script>
------------------------------

Note* -This will work unless and untill struts framework dont change the order of the childNode when rendering.

Thanks

I have done the following to avoid the problem.

On the JSP

 <s:datetimepicker key="subsReg.label.dob" displayFormat="dd/MM/yy"
				name="inputdob" required="true" />   

Action Class Input Method

 inputdob=Utilities.DateToDateString(BTSLUtil.currentUtilDate());   

Helper Class Method

 
public static String DateToDateString(java.util.Date d)
throws ParseException {

	SimpleDateFormat sdf = new SimpleDateFormat("dd'/'MM'/'yy");
	sdf.setLenient(false); 
	String dateString = sdf.format(d);
	return dateString;
}
   

That way the dateTimePicker shows the current date as the default date. If some other format is entered, the dateTimePicker replaces it with the current date automatically. If the date is removed, then in the validate() method I set the inputdob variable as null explicitly to not show NaN/NaN/NaN and add an action error.
