ArrayIndexOutofBoundsException

hi,

I have an application where i use a RFC to Zsm_Actual_Allocation_Input to take input values like startDate,endDate, skills

and execute and populate values in a table.While i pass values for 'skills' only and execute the RFC, it runs fine and

populate values in the table .But while i pass the values for startDate,endDate it always throws an exception saying

java.lang.ArrayIndexOutOfBoundsException: -1

Any clue regarding the error??

Am posting my code along with this :

IPublicTdc_DataCust.IZsm_Actual_Allocation_InputNode AllocationInputNode = wdThis

.wdGetTdc_DataCustController()

.wdGetContext()

.nodeZsm_Actual_Allocation_Input();

Zsm_Actual_Allocation_Input input = new Zsm_Actual_Allocation_Input();

for(int i = 0;i<AllocationDetailsNode.size();++i)

{

AllocationDetailsElement = AllocationDetailsNode.getCtx_vn_AllocationDetailsElementAt(i);

Date dt = AllocationDetailsElement.getStartDate();

try

{

input.setR_Skills("X");

input.setFrom_Date(dt);

input.setTo_Date(AllocationDetailsElement.getEndDate());

}

catch(Exception e)

{

wdComponentAPI.getMessageManager().reportException(""+ e.toString(),false);

}

}

AllocationInputNode.bind(input);

NB : AllocationDetailsNode is the node containing the values of Startdate and Enddate entered by the user from the front-end.
