UIX Javascript Error with Date Picker

Question

Hi all,
I am using JDeveloper 10.1.2.1.0 with JHeadstart 10.1.2.2.32 to create UIX pages. I have a page with a filter by search field. If I select the date picker on this page in IE version 6 or 7, I get the following javascript error:
Error: 'length' is null or not an object
I have found this in the Common2_2_20.js, which is part of the jslibs
function _accumulateNumber(
a0,
a1
var a2=a0.currIndex;
var a3=a2;
var a4=a0.parseString;
***var a5=a4.length;***
if(a5>a3+a1)
a5=a3+a1;
var a6=0;
while(a3<a5)
var a7=parseDigit(a4.charAt(a3));
if(!isNaN(a7))
a6*=10;
a6+=a7;
a3++;
else
break;
if(a2!=a3)
a0.currIndex=a3;
return a6;
else
return(void 0);
}With Firefox 1.5.0.4, I can get the date selector window to open, but when I select a date value, I get this javascript error:
a0.select() is not a function
I have found this in the Common2_2_20.js also. Here is the code where the error is occuring.
function _dfsv(
a0,
a1
if((a0==(void 0))||(a1==(void 0)))
return;
a1+=_getTimePortion(a0);
var a2=new Date(a1);
var a3=_getDateFieldFormat(a0);
var a4=a0.value;
var a1=a3.format(a2);
if(a0.value!=a1)
if(a0.onchange!=(void 0))
if(_agent.isIE)
a0.onpropertychange=function()
var a5=window.event;
if(a5.propertyName=='value')
a0.onpropertychange=function(){};
a0.onchange(a5);
a0.value=a1;
else
a0.value=a1;
var a5=new Object();
a5.type='change';
a5.target=a0;
a0.onchange(a5);
else
a0.value=a1;
***a0.select();****
a0.focus();
}I am able to use the date picker on other pages and even different parts of this page. The date search field is of type dateField.and is part of a switcher. Does anyone have any ideas as to why this is occuring or how I can work around it? Thanks in advance. I really appreciate all of your help.

Thanks for the reply. As a matter of fact, in my case the error happens in a UIX page generated by JHeadstart. I did some JavaScript debugging using the FireBug Firefox entension and I found that it is some JHeadstart JavaScript that causes this problem.
The JHeadstart JavaScript passes on an array of input elements to the AFD JavaScript function and the problem arises when the select() method is called on the array, rather than an input element in the array.
I will try to solve my issue by modifying the JHeadstart JavaScript code. Please see the JHeadstart forum somewhere in the near future for my post(s) about this :-)
Thanks, Wouter
