Adding Chart Refresh Method

Add the following method to EquipWorkOrderDC.java. This method calls the retrieveData() method to execute a data service aggregation request that retrieves a fresh set of data from EnterpriseOne. This method is normally called when the user selects a different radio button to summarize by a different F4801 column.

    public void refreshChartData(String chartType)
    {
        if (loginEnv != null)
        {
            logger.finest("***** Retrieving new chart data. *****");
            retrieveData(chartType); 
        }
        else
        {
            logger.severe("***** LoginEnvironment is null.  Unable to retrieve new chart data. *****");
            processErrorException("Connection failed. Please contact your system administrator");
        }
    }
