I've been struggling with this for hours, so I thought maybe someone
else's eye can see it. In my main application, for testing puproses,
I have hard coded some XML:
<questions>
<question id="1">
<selected>1</selected>
<selected>5</selected>
</question>
<question id="2">
<selected>1</selected>
<selected>5</selected>
</question>
<question id="3">
<selected>1</selected>
<selected>5</selected>
</question>
</questions>
This is the dataprovider for a TileList that uses a custom
itemRenderer. My itemRenderer has five buttons that correspond to
selections 1-5, and these have the ID's aBtn-eBtn. When a user
clicks on a button that is selected, I want to remove the selected
element that contains the value equivalent to the button they
selected. By the same token, if the button is not selected, I want
to add a selected node.
If no nodes are selected on the question and I add the node from
scratch, there is no problem. My code works as expected. However,
when the nodes come in with the data object, Flex does not see that
there are any nodes with that value. I think it might be a data
typing issue, but I have cast the data type to several different
types without success.
This is my function that _should_ be working:
private function changeSelected(theBtn:Button,
toggle:Boolean=false):void {
selectBtn(theBtn, toggle);
var i:int;
var selNum:int = theBtn.label.charCodeAt() - 64;
trace("typeof selNum " + typeof selNum);
var miniXML:XML = XML('<selected>'+selNum+'</selected>')
if (!isEditing){
if (data.selected.length()>0){
trace(data.(selected==XML(selNum)));
if (data.(selected==selNum).length()<1){
//add the selected node to the data
object
data.appendChild(miniXML);
} else {
//remove the selected node from the
data object
for (i=data.selected.length()-1;
i>=0; i--){
if (data.selected[i] ==
selNum){
delete data.selected
[i];
}
}
}
} else {
//no children exist at all...add
data.appendChild(miniXML);
}
} else {
//editing
//delete all previously selected nodes
for (i=data.selected.length()-1; i>0; i--){
delete data.selected[i];
}
//check to see if this button is "on"
//if so, add it back
if (theBtn.styleName == 'selectedBtn'){
data.appendChild(miniXML);
}
}
}
I am only testing the logic where isEditing is false right now.
Thanks in advance for any insight anyone can add.
