Unfortunately there is no simple 'if' processor in Mule. Choice with a dummy otherwise route or filters are the way to go for now.

There is a good discussion on this here: <a href="https://www.mulesoft.org/jira/browse/MULE-6129" rel="nofollow noreferrer">https://www.mulesoft.org/jira/browse/MULE-6129</a>. THis has further links to possible enhancements such as an if/detour router.

Mule 4 UPDATE

In mule 4, you can now define a choice router with no need for an <code>otherwise</code> route. And filters no longer exist

You can get close with an async or enricher scope and a filter. It's not as elegant as a true <code>&lt;if&gt;</code> processor (<a href="https://www.mulesoft.org/jira/browse/MULE-7136" rel="nofollow noreferrer">or a standalone <code>&lt;when&gt;</code></a>), but you don't need a wasted <code>&lt;logger&gt;</code> to satisfy the <code>&lt;otherwise&gt;</code>.

Async method (when you don't need the payload afterwards):

<pre><code>&lt;async&gt;
 &lt;expression-filter expression="#[payload == 'red']" /&gt;
 &lt;logger category="com.box.integration.experiment" message="That's my favorite color!" level="INFO" /&gt;
&lt;/async&gt;
</code></pre>

Enricher method (when you do):

<pre><code>&lt;enricher target="#[variable:colorName]"&gt;
 &lt;processor-chain&gt;
 &lt;expression-filter expression="#[payload == 'red']" /&gt;
 &lt;set-payload value="vermillion" /&gt;
 &lt;/processor-chain&gt;
&lt;/enricher&gt;
</code></pre>

blocks|key|2956006|text|在mule流中，如果使用消息路由器而不设置部分中的处理器，且MuleMessage不匹配任何子句，则会引发异常。要实现条件行为，当前穆尔需要在on子句上设置一个虚拟处理器。一个可用性改进是，如果没有匹配的子句，并且没有提供https://www.mulesoft.org/jira/browse/MULE-6129的处理器，则允许消息由流的其余部分处理。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2956007|entityMap|0|LINK|mutability|MUTABLE|url|https://www.mulesoft.org/jira/browse/MULE-6129^0|33|1A|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

In a mule flow, when using a message router without setting a Processor in the section, and the MuleMessage does not match any of the clauses, an exception is thrown. To achieve a conditional behavior currently mule requires to set a dummy processor on the otherwise clause. One usability improvement would be letting the message be processed by the remaining part of the flow if no clause was matched and no processor provided
<a href="https://www.mulesoft.org/jira/browse/MULE-6129" rel="nofollow noreferrer">https://www.mulesoft.org/jira/browse/MULE-6129</a>

I want to make a decision in a Mulesoft flow, and have looked at the Choice Flow Control. My problem, is that I want to do something if the condition is true, and nothing if it is false, something like:

<pre><code>if (condition == true)
 do some work
</code></pre>

or, in probably incorrect xml:

<pre><code>&lt;choice doc:name="call a subflow if the test is true"&gt;
 &lt;when expression="#[flowVars.someVariable == True]"&gt;
 &lt;flow-ref name="doSomething" doc:name="do another thing"/&gt;
 &lt;/when&gt;
&lt;/choice&gt;
</code></pre>

no else clause, and no default flow. How is this implemented in a Mulesoft flow?
I could cheat, and throw a logging call into a default flow, but I would prefer not to.

How do I implement IF in mulesoft
