Item Renderer doesn't work with just one Item :-(

[Nate Pearson-2]

I have a custom item render on a bar chart.  

When my the data provider for my bar chart has just one item in it the set data function is never gets called.  Updatedisplaylist doesn't trigger and my bar chart is blank.

Any ideas?  I've had this bug for a while but I need to figure it out now.

Thanks!

I seem to remember some time back (Although my memory is not what it used to be) that if returned data only has one item it is not converted to an array (ie. it is only a string). You may like to try checking to see if it is an array and, if not, coercing it to an array.

I could be completely off track here though.

Well my label shows up on the graph, it just doesn't call the item renderer (I think).  I get a label on the left side and a blank graph.  I try to debug the renderer and I can't hit any break points.

Any other ideas?

I have a filter function applied.  Could that be part of it?

Possibly. Is there any way you could put together a small example of what you are seeing?

If you are using the default resultFormat, this behavior is an issue.  I'd
advise "e4x".  Or, test the result to see what it contains and conditionally
react.  ArrayUtil.toArray might also be helpful.

Nope, I'm putting my data into an array collection before I bind it.
