Hi,

I'm trying to call the code below from a button on my form and for some reason I keep getting this error:

"'XDocument.DOM.selectSingleNode(...)' is null or not an object"

The code:

function btnCosting::OnClick(eventObj)
{
var clicked = XDocument.UI.Confirm("You will not be able to undo this operation. Do you wish to continue?",1);
if(clicked == 1) {
XDocument.DOM.selectSingleNode("/my:myFields/my:header/my:costingsComplete").text = 1;
}
}

I can't understand why..

Hi,

Check once, this Xpath is correct("/my:myFields/my:header/my:costingsComplete"):

I hope this will help for you.

Well this is what I get if I go to the field under Data Sources and select Copy XPath. The field is in a group called Header under myFields.

Try to delete the first "/" in front of my:myFields.
You can actually always use an Expression Box to find out the correct xPath. Just put the ExBox to your form, point it to the control/node you want to know the xPath for and then check the "Advanced - edit xPath" check box.

Hi,

I think, In Xpath you typed as "header", but in datasource it is "Header".

Please correct it, then it will work for you.

I hope this will work for you.

Ok I tried removing the initial "/" - same result.

According to the exBox the xPath is this "my:header/my:costingsComplete", this didn't work either.

Also changed "header" to Header but that didn't work. The group "header" is one I created and it doesn't have a capital "H" so it should be as typed.

Thanks for everyones help so far. I also have the exact same code below trying to do the same thing with a different field. It always prompts but then can't seem to find the field.

Hi,

I tried with code you have given, it is worked for me, (i.e,i did not get any error).

Still doesn't work for me for some reason!

hi edove,

put "/" initially and try to write the XPath manually once, with case sensitive. I worked around with your specification and is working for me.
