Hi,

I import an xml file into a form by custom code. Now I wanted to insert a link in the custom task pane which resets the form.
This peace of code resets the form.

var nodes = XDocument.DOM.selectNodes("/*");
while(node = nodes.nextNode())
      node.text=" "; 

But when I wanted to import another xml file I get a nullpointer exception. It seems that this peace of code deletes the whole dom or why can't I import the xml at the second time?

Regards,

Hi Buki,
My guess is that it's a bug in your custom import code. I'd have to look at that. Sorry for not responding sooner!

Hi,

I guess my import code works fine. When I import the same xml file once, twice or three times without reseting it just adds the contents to the form. But if I use the reset function, this next time I use the import function I get the error "selectSingleNode(..) Null or no object".
This is an example of my import code:

if (gdomImported.selectSingleNode("/NOTIF/NOTIF_PARTNER/item[PARVW_VTEXT/text()='Autor']/PARNR_NAM"))
{
  objDataDOM.selectSingleNode("/my:ECx/my:BASIC_DATA/my:BD_INITIATOR").text = gdomImported.selectSingleNode("/NOTIF/NOTIF_PARTNER/item[PARVW_VTEXT/text()='Autor']/PARNR_NAM").text; 
}
if(gdomImported.selectSingleNode("/NOTIF/NOTIF_TEXT/item[1]/TDLINE"))
{
  objDataDOM.selectSingleNode("/my:ECx/my:BASIC_DATA/my:BD_REASON_CR").text = gdomImported.selectSingleNode("/NOTIF/NOTIF_TEXT/item[1]/TDLINE").text; 
}
var parent = objDataDOM.selectSingleNode("/my:ECx/my:BASIC_DATA");
var firstRow = objDataDOM.selectSingleNode("/my:ECx/my:BASIC_DATA/my:BD_CHANGEDESC");             
var i = 2;
while (gdomImported.selectSingleNode("/NOTIF/NOTIF_TEXT/item["+i+"]/TDLINE"))
{
  var newRow = firstRow.cloneNode(true);
  newRow.text = gdomImported.selectSingleNode("/NOTIF/NOTIF_TEXT/item["+i+"]/TDLINE").text; 
  parent.insertBefore(newRow, firstRow);
  i++;
}

This is mainly taken from the CD import example provided by Microsoft.
But if you have any hints on how to clear a form by script, I'd appreciate that very much.

Best regards,

Hi buki79,

This is the problem with your reset code. your reset code is making the root node empty. you can use below reset code instead:

var nodes = XDocument.DOM.selectNodes("//*");
while(node = nodes.nextNode())
{
if(node.selectNodes("child::*").length == 0)
{
node.text = "";
}
}

Thanks for your help! That works fine!
