Thanks for the response everyone! I have made the changes that was
suggested and still I'm getting an error msg for null reference. To
Jay, it is one element of an array collection (that has like 5-6
different objects), not one field or string. The line of code that the
compiler is pointing to is...
private var tempAC:ArrayCollection = new ArrayCollection();
private function myFunc(event:ResultEvent):void
{
if(event.result.blah.blah is ArrayCollection){ //if array has multiple
elements
myArrayCollection = event.result.blah.blah;
}else{ //if array has just one element
tempAC.addItem(event.result.blah.blah); //this is where I'm
getting the null error
myArrayCollection = tempAC;
}
}
My xml would look similar to this...
<response>
<values>
<value>
<id>123</id>
<name>kyle</name>
<somethingElse>blah blah</somethingElse>
</value>
</values>
</response>

element?
simply move the following line inside the else clause:
myArrayCollection = tempAC;
