Error Message

In order for an error message to appear on screen, a java exception must be created and thrown.

Create the Exception class.
1. All exception classes must extend com.crm.exception.CRMValidationException.
2. All exception methods should have a com.crm.exception.CRMValidationException object as an input parameter and use setMessage method of com.crm.exception.CRMException class.
  1. To create the exception method:
    1. Use com.crm.businessobject.CRMSession object as an input parameter and any other String input parameters needed.
    2. Put all String input parameters in a String ArrayList.
    3. Use setMessage method of com.crm.exception.CRMException class to construct the exception message.

AccountTerminationException.java

 public class AccountTerminationException extends CRMValidationException {
	/**
	 * You are not allowed to terminate the Accounts Receivable %1. This is only allowed for Active or Suspended accounts.
	 * 
	 * @param crmSession - the session object
	 * @param value - the exception value
	 * @throws Exception
	 */
	public AccountTerminationException(CRMSession crmSession, String value) throws Exception {

		super();

		ArrayList<String> parameters = new ArrayList<String>();
		parameters.add(value);

		try 
		{
			setMessage(this.getClass().getName().toUpperCase(), crmSession, parameters);
		} 
		catch (Exception e) 
		{
			e.printStackTrace();
		}
	}
}

2. Define the exception in the messages.xml file. Use a unique key for the expression tag. For more information on customising messages metadata, go to Customize Messages Metadata.

messages.xml

<messages>
	<message>
		<code>COM.CRM.EXCEPTION.ACCOUNTS.ACCOUNTTERMINATIONEXCEPTION</code>
		<expression>key_com_crm_exception_accounts_accountterminationexception</expression>
		<description>You are not allowed to terminate the accounts receivable. This is only allowed for Active or Suspended accounts.</description>
	</message>
	.
	.
	.
</messages>

3. Define the exception in English translation properties file, by using the expression tag key defined in metadata messages file as the entry key, and specifying the exception message. Use %<number> where the input parameters should be placed. Note that <number> is their index+1 in parameters array list.

translation_eng.properties

<properties>
	<entry key="key_com_crm_exception_accounts_accountterminationexception">You are not allowed to terminate the accounts receivable %1. This is only allowed for Active or Suspended accounts.</entry>
	.
	.
	.
</properties>

4. Throw the exception.

InvalidAccountCreditPeriodException.java

public void validateTermination(CRMDOAccountReceivable account)  throws Exception, AccountTerminationException{
		
		if (account.getLifeCycleState()==null || 
		   (!account.getLifeCycleState().equals(AccountReceivableLifeCycleState.ACTIVE) && 
			!account.getLifeCycleState().equals(AccountReceivableLifeCycleState.SUSPENDED)))
		{
		    throw new AccountTerminationException(getCRMSession(), account.getNumber());
		}
		...
}

Question Messages

Question Message

In order for a question message to appear on screen, two java methods should be created.

Create the java method that will display the question.
1. Use showConfirmQuestion method of com.crm.process.CRMUI class to display the confirmation question.
  1. Define the method to be called if the user clicks 'YES' (class name, method name, question code) and message parameters, as input parameters for showConfirmQuestion method.
2. Continue implementing what should be executed right after postPayment method, if the user clicks 'YES', or right after the user clicks 'NO'.
Create the java method that will be called if the user clicks 'YES'

CRMUIPaymentBean.java

...

	/**
     * Posts payment. (Sets posted date, generates transaction number, performs allocations).
     * 
     * @param payment        a payment to post
     * @return                updated payment
     * @throws Exception
     */
    public CRMDOPayment postPaymentButton(CRMDOPayment payment) throws Exception {
        
		//parameters: interface class, function and question message
        showConfirmQuestion(
                "CRMUIPayment",
                "postPayment",
                "CONFIRM_FINANCIAL_TRANSACTION_SAVED_AS_POSTED",
                new String[]{"Payment"});
        
        return payment;
    }
	/**
     * Posts payment. (Sets posted date, generates transaction number, performs allocations).
     * 
     * @param payment		a payment to post
     * @return				updated payment
     * @throws Exception
     */
    public CRMDOPayment postPayment(CRMDOPayment payment) throws Exception {
    	return processFinTransactionBean.postPayment(payment);
    }

...

3. Define the question code in metadata messages file.

messages.xml

 	<message>
         <code>CONFIRM_FINANCIAL_TRANSACTION_SAVED_AS_POSTED</code>
         <expression>key_confirm_financial_transaction_saved_as_posted</expression>
         <description>Confirm Action</description>
    </message>

4. Define the question in the English translation properties file, by using the expression tag key defined in metadata messages file as the entry key, and specifying the question message. Use %<number> where the message parameters should be placed. Note that <number> is their index+1 in message parameters array list.

translation_eng.properties

 	<entry key="key_confirm_financial_transaction_saved_as_posted">%1 is going to be saved as Posted. Do you wish to continue?</entry>

Informational Messages

Informational Message

In order for n informational message to appear on screen, you have to

Create an instance of com.crm.process.InfoMessage object, defining the session, message code, message parameters, session real path, and organisation id as shown below.
Use showInfoMessage method of com.crm.process.CRMUI class to display the message on screen.

saveGeneralSetting method

		/**
	 * Saves a general setting.
	 * 
	 * @param generalSetting - the general setting to save
	 * @return the saved general setting	
	 * @throws Exception
	 */
    public GeneralSetting saveButton(GeneralSetting generalSetting) throws Exception {
    	
    	systemSettingBean.validateGeneralSettings(generalSetting);
    	systemSettingBean.saveGeneralSettings(generalSetting);
    	
    	InfoMessage infoMsg=new InfoMessage(getCRMSession(),"LOGOUT_INFO_MSG", null, getCRMSession().getRealPath(), getOrganisationID());
    	
    	showInfoMessage(infoMsg);
    	
    	return generalSetting;
    }

3. Define the message code in metadata messages file.

messages.xml

	<message>
        <code>LOGOUT_INFO_MSG</code>
        <expression>key_logout_info_msg</expression>
        <description>Logout to apply the changes</description>
    </message>

4. Define the message in the English translation properties file, by using the expression tag key defined in metadata messages file as the entry key, and specifying the question message. Use %<number> where the message parameters should be placed. Note that <number> is their index+1 in message parameters array list.

translation_eng.properties

	<entry key="key_logout_info_msg">Please logout and login again so that changes will be applied.</entry>
