Variable of Type "Object" is getting Null in script task

Question

I have 3 components as below
1.   Execute Sql Task ---> It will fetch The data from Database using ConnectionType "OLEDB" ("Full Result Set" its returning) and Store it in the Variable as below,
      "ConfigDetails"   "Scope --> Package"    "Type -  Object".
2.  Script Task  (First) ---->   Here "ConfigDetails" Variable is part of "ReadOnlyVariables", So i am accessing this varaible and populating data from it in the Data Table object as below,
OleDbDataAdapter configAdapter = new OleDbDataAdapter();
DataTable dtConfigurationList = new DataTable();
object config = Dts.Variables["ConfigDetails"].Value;
configAdapter.Fill(dtConfigurationList, config);
  So here i am successfull in populating data in the data table .
3. Script Task (Second)--> Same thig i am doing in second script task also as "First"
Here "ConfigDetails" Variable is part of "ReadOnlyVariables", So i am accessing this varaible and populating data from it in the Data Table object as below,
OleDbDataAdapter configAdapter = new OleDbDataAdapter();
DataTable dtConfigurationList = new DataTable();
object config = Dts.Variables["ConfigDetails"].Value;
configAdapter.Fill(dtConfigurationList, config);
 So here it will execute successfully without any error. But no data is there in the data table .
If i skip first script task, second script task is able to populate the data. But i am not righting any code to nullify the object and its part of "Read Only Varaibles."
  So please help me what i am doing wrong.
            configAdapter.Fill(dtConfigurationList, config);

What do you pass to the config variable?
