If
all the conditions in a Choice router in MuleSoft are valid, the first
condition that evaluates to true will be executed and the others will be ignored.
This
is similar to an if-else statement in programming, where only the first true
condition is executed.
Here
is an example of a Choice router with two conditions:
XML
<choice>
<when expression="message.payload = '1'">
<logger message="Condition 1 is met." />
</when>
<when expression="message.payload = '2'">
<logger message="Condition 2 is met." />
</when>
<otherwise>
<logger message="No conditions are met." />
</otherwise>
</choice>
If the message payload is 1, the first condition will evaluate
to true and the logger message "Condition 1 is met." will be printed
to the console. The second condition will not be evaluated, as the first
condition has already evaluated to true.
If the message payload is 2, the second condition will evaluate
to true and the logger message "Condition 2 is met." will be printed
to the console. The first condition will not be evaluated, as the second
condition has already evaluated to true.
If the message payload is anything other than 1 or 2, the
otherwise clause will be executed and the logger message "No conditions
are met." will be printed to the console.
Here is an example of the output of the Choice router if all the
conditions are valid:
Condition 1 is met.
This is because the first condition is the first one to evaluate to true.
In general, it is not recommended to have multiple conditions in
a Choice router that can all evaluate to true. This can make the flow difficult
to read and maintain. It is better to use separate flows or sub-flows to handle
the different conditions.
