[flexcoders] Statically adding one more item to the dynamically driven combobox dataprovider.

[kotha poornima]

Hi All,
In my project i have a combobox in which i need to add dynamic values from the 
xml file and in addition i need to add one static value "All" to the combobox 
dataprovider.
For combobox dataprovider iam directly giving xml values like this:

usecases1.dataProvider=cbolXML.Market[0].child("UseCase").attributes();

usecases1 is nothing but combobox and cboxXML is an xml file from which iam 
reading the data's for the combobox.

SO, here how can i add one more static value "All" to the above data coming 
from the xml file.

i dont find any addItem or push methods for combobox dataprovider.

If i am using arraycollection or array its not giving the correct data but its 
appending ALL to the data from the xml.

Anyone can help me out of this.

Thanks in Advance,
Poornima
