[jira] [Updated] (CAMEL-8738) Referring to constants using type

["Umair Saleem (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CAMEL-8738?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Umair Saleem updated CAMEL-8738:
--------------------------------
    Description: 
Hi,

In documentation link http://camel.apache.org/simple.html following is written

Camel 2.11: To refer to a type or field by its FQN name. To refer to a field you can append .FIELD_NAME. For example you can refer to the constant field from Exchange as: org.apache.camel.Exchange.FILE_NAME

When I tried it it works. 

But for example I have class Constants which contain inner class InnerConstants which have a field. I cannot access it from following way.
${type:Constants.InnerConstants.fieldName}. 

Exception Found: Cannot find class Constants.InnerConstants.fieldName

Following is the structure of my Constant class

class Constants  {
	public static String test ="Test1234";
	public static class InnerConstants {
		public static String fieldName = "fieldName"
	}
}

My route was:

<route>
             <camel:from uri="stream:in" />
             <camel:setBody><simple>${type:Constants.InnerConstants.fieldName}</simple></camel:setBody>
             <log loggingLevel="INFO" message="${body}" />
</route>

Let me know if you need any other clarification.
