Buggy source:

Fixed version (ground truth):

      IElement element=tableEditorModel.getElement();
      String componentName=null;
      if (element != null && element instanceof INode) {
        componentName=((INode)element).getComponent().getName();
      }
      Object data=SimpleClipboard.getInstance().getData();
      if (data == null || !(data instanceof List)) {
        return false;
      }
      @SuppressWarnings("String_Node_Str") List dataList=(List)data;
      boolean sameNumberOfParamAssSourceTable=true;
      if (dataList.isEmpty() || !(dataList.get(0) instanceof HashMap)) {
        return false;
      }
      @SuppressWarnings("String_Node_Str") int sourceColumnNumber=((HashMap)dataList.get(0)).size();
      int colNum=0;
      if (componentName != null && componentName.equals("String_Node_Str")) {
        colNum=getExtendedTableViewer().getTableViewerCreator().getTable().getColumnCount() - 1;
      }
 else {
        colNum=getExtendedTableViewer().getTableViewerCreator().getTable().getColumnCount();
      }
      if (data != null) {
        if (colNum == sourceColumnNumber) {
          sameNumberOfParamAssSourceTable=true;
        }
