Parameter mapping error in webdynpro java

Question

Hi All,
I have a table and the columns of the table are created dynamically(assume I have Colum A & Column B).
The table cell editor is input field. On hitting enter on the input field of the column, I want to get the column name.
But I am getting com.sap.tc.webdynpro.services.exceptions.WDIllegalArgumentException: Parameter col not found.
Where am I going wrong?
In wdModify view I have the following lines of code
retString[] // this array contains the column header names
int  j = retString.length;
for(int i=0;i<j;i++)
IWDAttributeInfo att_Adjust_value = wdContext.nodeFinalStockTons().getNodeInfo().addAttribute("att_Adjust_value"+i,"ddic:com.sap.dictionary.integer");
IWDAttributeInfo attrib_Adjust = wdContext.nodeFinalStockTons().getNodeInfo().getAttribute("att_Adjust_value "+i);
IWDTableColumn tabColumn_Adjust =(IWDTableColumn)view.createElement(IWDTableColumn.class,"ColumnAdjust"+i);
//Add caption to Column
IWDCaption Cap_Adjust = (IWDCaption)view.createElement(IWDCaption.class,"CapTonsAdjust"+i);
Cap_Adjust.setText(retString<i>);
tabColumn_Adjust.setHeader((IWDCaption)Cap_Adjust);
//Table cell editor is of type Input field
IWDInputField Input_Field_Adjust = (IWDInputField)view.createElement(IWDInputField.class,"Input_Field_Adjust"+i);
Input_field_Adjust.bindValue(attrib_Adjust);
tabColumn_Adjust.setTableCellEditor((IWDTableCellEditor)Input_Field_Adjust);
table_adjust =(IWDTable)view.getElement("AdjustTable" ); // get Table
table_adjust.addColumn(tabColumn_Adjust); //bind column
//Creating action
IPrivateFINAL_STOCK_View.WDActionEventHandler adjustActHandler= IPrivateFINAL_STOCK_View.WDActionEventHandler.ON_HIT_ENTER;
IWDAction genericEventAction=wdThis.wdCreateAction(adjustActHandler, "onActiononHitEnter");
wdThis.wdGetOnHitEnterAction();
genericEventAction.setEnabled(true);     
IWDInputField inputField =
(IWDInputField)((IWDTableColumn)(table_adjust.getView().getElement("ColumnAdjust"i))).getView().getElement("Input_Field_Adjust"i);
inputField.setOnEnter(wdThis.wdGetHITAction());
inputField.mappingOfOnEnter().addSourceMapping("col",retString<i>); // source name, new name
public void onActionHitEnter(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String col)
