FuseESB 7.1 - ErrorHandler Properties Modified by Design Mode

[mhuisking_michael.c.huisking]

Hi,

I've been playing around with the new version of the IDE (nice) and am having a problem when I define a DeadLetterChannel error handler and attach it to the camel context and then switch to the graphical design view.

For an example, I used the default camel-context.xml file that is generated by the Spring archetype, along with a simple little error handler def:

<?xml version="1.0" encoding="UTF-8"?>
<!-- Configures the Camel Context-->

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/spring"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">
       
  <camelContext errorHandlerRef="dlc" xmlns="http://camel.apache.org/schema/spring">
    <errorHandler id="dlc" type="DeadLetterChannel" deadLetterUri="log://deadLetterQueue">
        <redeliveryPolicy delayPattern="1:60000;2:300000;3:3600000;4:7200000;5:14400000;6:43200000" retryAttemptedLogLevel="ERROR" asyncDelayedRedelivery="true" maximumRedeliveries="6"></redeliveryPolicy>
    </errorHandler>
    <route>
        <description>here is a sample which processes the input files
         (leaving them in place - see the 'noop' flag)
         then performs content based routing on the message using XPath</description>
        <from uri="file:src/data?noop=true"></from>
        <choice>
            <when>
                <xpath>/person/city = 'London'</xpath>
                <log message="UK message"></log>
                <to uri="file:target/messages/uk"></to>
            </when>
            <otherwise>
                <log message="Other message"></log>
                <to uri="file:target/messages/others"></to>
            </otherwise>
        </choice>
    </route>
</camelContext>

</beans>

If I save it this way (without switching over to "Design" view) and run it everything works fine.  However, if I switch to Design view, my error handler becomes:

    <errorHandler rollbackLoggingLevel="WARN" level="ERROR" deadLetterUri="log://deadLetterQueue" type="DeadLetterChannel" id="dlc">

Those added attributes of rollbackLoggingLevel and level are not valid for a DeadLetterChannel error handler (Error = "IllegalArgumentException: Attribute rollbackLoggingLevel can only be used if type is TransactionErrorHandler")

Is there something about this particular route that's causing the designer to think this is a TransactionErrorHandler instead of a DeadLetterChannel type handler?

This is for FuseIDE 7.1.0.fuse-047  32 bit Windows7

Thanks in advance,

Mick

Hi

Thanks for reporting. I have logged a ticket

You can define the error handler outside  style instead. Though its not using a nice namespace, and its more verbose. But then the switching to design editor should not cause a problem.

Thanks!

Just for reference, the "bean" method would look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!-- Configures the Camel Context-->

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/spring"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">
       
  <bean id="dlc" class="org.apache.camel.builder.DeadLetterChannelBuilder">
    <property name="deadLetterUri" value="log://deadLetterQueue"></property>
    <property name="redeliveryPolicy" ref="dlcRedeliveryPolicy"></property>
  </bean>
 
   <bean id="dlcRedeliveryPolicy" class="org.apache.camel.processor.RedeliveryPolicy">
    <property name="delayPattern" value="1:60000;2:300000;3:3600000;4:7200000;5:14400000;6:43200000"></property>
    <property name="retryAttemptedLogLevel" value="ERROR"></property>
    <property name="asyncDelayedRedelivery" value="true"></property>
    <property name="maximumRedeliveries" value="6"></property>
  </bean>
       
  <camelContext errorHandlerRef="dlc" xmlns="http://camel.apache.org/schema/spring">
    <route>
        <description>here is a sample which processes the input files
         (leaving them in place - see the 'noop' flag)

        </description>
        <from uri="file:src/data?noop=true"></from>
        <choice>
            <when>
                <xpath>/person/city = 'London'</xpath>
                <log message="UK message"></log>
                <to uri="file:target/messages/uk"></to>
            </when>
            <otherwise>
                <log message="Other message"></log>
                <to uri="file:target/messages/others"></to>
            </otherwise>
        </choice>
    </route>
</camelContext>

</beans>

I fixed this in Camel today. So any new release of Fuse IDE with updated Camel should have this fixed out of the box.
