DEVELOPERS FORUM - Set a list value from an action

CycleOp - Thursday, June 30, 2011 4:32 AM:

Hi all,

I have a list attribute on a form. I wrote an method and attached it as an action to the ItemType.

When I try the following code I get errors. Seems I am not retrieving the attributes on the form as I should.

Here the code:

var iNumber = document.getElementById("item_number");

alert(iNumber.value); //returns null

Any ideas ?

Hi,

Does the item_number id exist in your HTML DOM?

Ok, I got it, with the help of Rolf from Aras (Thanks Rolf!).

When running an action (from menu - select the "actions" menu and run your method - You do not have access to the "document" element.

Instead you get the "this" to the Item itself. So the code goes like that:

var itemLock = this.fetchLockStatus();

alert (itemLock);

if (itemLock > 1 || itemLock < 0)  

{

 top.aras.AlertError("cannot update. Locked by someone else");

  return;

}

var amlcmd;

if (itemLock === 1)

{

  amlcmd = top.aras.newIOMItem(this.getAttribute("type",""),"update");

}

if (itemLock === 0)

{

  amlcmd = top.aras.newIOMItem(this.getAttribute("type",""),"edit");

}

amlcmd.setID(this.getID());

amlcmd.setProperty("issuestatus","Cancelled");

amlcmd.setAttribute("serverEvents","0");

amlcmd = amlcmd.apply();

return amlcmd;
