problems with setting spark list dataprovider in actionscript

[cyber0897]

hey guys... so i have an array collection named tagArr that looks like this:

[0] => "name 1"

[1] => "name 2"

[3] => "name 3"

...

...

in actionscript i try to set the dataprovider of a list named regionList

so i do soemthing like

regionList.dataProvider = tagArr;

and i get an error: "TypeError: Error #1009: Cannot access a property or method of a null object reference."

any ideas why its doing this???
