----------------------------------------------------------------
I understand that I can't get the length of the array because it's a property
of it.
So I converted it to an ArrayList in order to be able to get the size of it.
This is a method and it exists.
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<routes xmlns="http://camel.apache.org/schema/spring";>
<route>
<from uri="timer:test?repeatCount=1"/>
<setBody>
<groovy>[[2, "Chaine_avec_des_underscores", 12, "c"], ["d4", "e5",
"f6"]]</groovy>
</setBody>
<split>
<simple>${body}</simple>
<log message="${body[1]}"/>
<setHeader headerName="splittedColumn1" >
<simple
resultType="java.util.ArrayList">${body[1].split("_")}</simple>
</setHeader>
<log message="${header.splittedColumn1}"/>
<setHeader headerName="splittedColumn2">
<simple>header.splittedColumn1.size</simple>
</setHeader>
<log message="${header.splittedColumn2}"/>
</split>
</route>
</routes>
{code}
But I get the following error:

It might be related to CAMEL-6260 but I see it is fixed in version 2.11.0 which
is the one I'm using.
