Subject nested catch-blocks in doCatch and doFinally
Date Tue, 17 Jun 2014 13:05:39 GMT
Hello,

I need to use nested catch-blocks in my project like the following:

from("direct:start")						
.doTry()
	.setBody(simple("doTry"))
	.to("stream:out")					
.doCatch(Exception.class)
	.setBody(simple("doCatch"))
	.to("stream:out")			
	.doTry()
		.setBody(simple("doTry in doCatch"))
		.to("stream:out")
	.doCatch(Exception.class)
		.setBody(simple("doCatch in doCatch"))
		.to("stream:out")
	.end()												
.doFinally()
	.setBody(simple("doFinally"))
	.to("stream:out")			
	.doTry()
		.setBody(simple("doTry in doFinally"))
		.to("stream:out")
	.doCatch(Exception.class)
		.setBody(simple("doCatch in doFinally"))
		.to("stream:out")					
	.end()					
	.stop()							
.endDoTry();


Compiler says: the method doFinally() is undefined for the type
ProcessorDefinition<capture#1-of ?> so Eclipse suggests  ("add cast to
method receiver") following:



((TryDefinition) from("direct:start")						
.doTry()
	.setBody(simple("doTry"))
	.to("stream:out")					
.doCatch(Exception.class)
	.setBody(simple("doCatch"))
	.to("stream:out")			
	.doTry()
		.setBody(simple("doTry in doCatch"))
		.to("stream:out")
	.doCatch(Exception.class)
		.setBody(simple("doCatch in doCatch"))
		.to("stream:out")
	.end()
	)												
.doFinally()
	.setBody(simple("doFinally"))
	.to("stream:out")			
	.doTry()
		.setBody(simple("doTry in doFinally"))
		.to("stream:out")
	.doCatch(Exception.class)
		.setBody(simple("doCatch in doFinally"))
		.to("stream:out")					
	.end()					
	.stop()							
.endDoTry();


but then at runtime I get:

java.lang.ClassCastException: org.apache.camel.model.CatchDefinition cannot
be cast to org.apache.camel.model.TryDefinition


	Whats wrong here, I can't see a syntax error ? Is it a bug ?
	
		thanks for any advice
