Htmldb_get & Checksum Required: Session Level

Question

Hi All,
I have a text field with some javascript on the "onchange" trigger to validate/format the value entered by the user.
All my application items' security are set to "Checksum Required: Session Level"
If a display, by using alert, the result of the javascript, it will pop-up a very long error saying something like "attempt to save item XXX in session state during show processing. item protection level indicates item may be set when accompanied by a session checksum. No checksum was passed..."
When I set the item's security to "unrestricted" it works fine.
Is there any way to set the checksum? Is it worth it?
Is thre any security issue if this item is set tom "unrestricted"?
Regards

Hello,
I'm not sure I'm following you Carl.
I've created the application item.
This is my application process code:
DECLARE
v_first_slash NUMBER(2);
BEGIN
v_first_slash := INSTR(:P5_OTU,'/');
IF v_first_slash <> 0 THEN
HTP.PRN(LPAD(SUBSTR(:P5_OTU,1,v_first_slash-1),2,0) || '/'
|| LPAD(SUBSTR(:P5_OTU,v_first_slash+1,LENGTH(:P5_OTU) - v_first_slash),3,0));
END IF;
END;
And then the javascript located in the region header is:
if (html_GetElement('P5_OTU').value){
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=validate_format_OTU',0);
get.add('P5_OTU',html_GetElement('P5_OTU').value)
gReturn = get.get();
if(gReturn)
{  html_GetElement('P5_OTU').value = gReturn  }
else
{  html_GetElement('P5_OTU').value = 'Wrong format'  }
get = null;
But I'm afraid I don't know what to do with the new application item.
Many thanks
