[flexcoders] Multiple filters on datagrid

[m_baker]

I have four comboboxes populated from arrays. I have a datagrid populated 
by an ArrayCollection. I can filter the ArrayCollection from each combo 
box individually, but I need to filter by multiple selections. For 
example, I may want to filter by UserID and Carrier and Origin.

The obvious solution is to run a conditional that appends a variable and 
use the variable in the filter conditional.

if(cboUserID.text != ""){
        filterVar = 'item.USER_ID == cboUserID.text'; 
}
if(cboCarrier.text != ""){
        filterVar = filterVar + 'item.Carrier == cboCarrier.text'; 
}

public function processFilters(item: Object):Boolean {
if (filterVar.toString()) {
                return true;}
                { 
 

                return false;
   } 


The problem is that the processFilters function won't accept the filterVar 
as a string. Is it a matter of using a different datatype or do I need to 
escape characters or is this not possible? Is there a better way to do 
this?
