var dbo:DBOperation=new
DBOperation();
dbo.getSolutionData("some sql
strings");
solutionList=dbo.list;
}
]]>
</mx:Script>

------------------------------------------------------------
My problem is I can get the data using DBOperation class,but I can not
assign it to solutionList by "solutionList=dbo.list;"
The debug information says dbo.list=null, however inside DBOperation
the "list" is full of data.
What's wrong with it??
Thanks!
