RE: [flexcoders] Re: Need help processing XML into Flex app
I am speaking about XML namespaces. If a node is abc:MyNode, then in the
e4 x expression you need to writhe myXML.abc::MyNode; Or declare and use a
Namespace
The single node behavior suggests that you have left the resultFormat at its
default object. And that is why you are not seeing the namespace issue,
and why you are not able to use e4x expressions.
resultFormat=object has a few benefits and many drawbacks. I advise
against using it. Look into this choice before you get too far to change.
Google or search the archives.

I guess I don't. I did add this to my mx:application tag:
xmlns:ws=com.draper.* and had
import com.draper.*;
in my script section, but without those it still runs fine.
After I sent you the note about looping through the array, I discovered that
Flex is seeing an array only if there are multiple occurrances. If there is
just one role, it treats it as a regular node, so no looping is required. So
my loop became:
roleList = ;
if (item.Roles.length == undefined) {
roleList = item.Roles.RoleName;
}
else {
for (i = 0; i item.Roles.length; i++) {
roleList = roleList + item.Roles[i].RoleName + \n;
}
}
return roleList;
Oh, and the reason I started looping was to add the line break; when I first
got results back, the values were just strung together like role1 role2
role3.

RE: [flexcoders] Re: Need help processing XML into Flex app
Ok, but that is cheating. I do it myself, but just so you know, looping
in XML usually means you gave up trying to figure out the right e4x
expression.

Tracy,
I got it! It turns out that Roles are returned as an array, since the
Roles node repeats. So this did it:
protected function displayRoles (item:Object, column:DataGridColumn):String
{
roleList = ;
for (i = 0; i item.Roles.length; i++) {
roleList = roleList + item.Roles[i].RoleName + \n;
}
return roleList;
}
That gave me a variable roleList with each role and a newline like:
User
Portal User
Administrator
Thanks again for your help.
Jim
RE: [flexcoders] Re: Need help processing XML into Flex app
Since some of your expressions were working, I assume you have handled the
namespace issues, is that correct?
In your post you have Rolename but the node is RoleName. Expressions are
case sensitive.
Another approach would be:
return item.Roles.children()[0].text();

Tracy,
Thanks for the lead. I'm having trouble getting it to recognize RoleName,
though (there is only one role name per role, by the way).
I did this for UserDescription just to prove the method:
protected function displayName (item:Object, column:DataGridColumn):String
{
return item.UserDescription;
}
...
mx:DataGrid...
mx:DataGridColumn headerText=Name labelFunction=displayName /
and that worked fine.
But for rolename, I did this (with and without the .text()):
protected function displayRoles (item:Object, column:DataGridColumn):String
{
return item.Roles.Rolename.text();
}
...
mx:DataGridColumn headerText=Roles labelFunction=displayRoles /
and no matter, what I get:
Error: Unknown Property: 'Rolename'.
I'm copying the actual XML here in case you can see something I'm missing. I
changed all the to a plus a space and all the / to / so nothing
should be lost when I submit this.
Thanks,
Jim
