Hi, I am trying with a task to read an XML file from a location and split by specific node and write each XML node into a separate file using batch job. I am using splitter in batch job input and in batch step, I am using the file connector to write the file. However, I am getting error as `ERROR 2018-08-10 15:38:01,801 [[apdev-handlexml-batch].FileReadingFlow.stage1.02] org.mule.exception.CatchMessagingExceptionStrategy:
********************************************************************************
Message : Object "java.lang.String" not of correct type. It must be of type "{interface java.lang.Iterable,interface java.util.Iterator,interface org.mule.routing.MessageSequence,interface java.util.Collection}" (java.lang.IllegalArgumentException)` .
Please help how to get avoid this error. Here is my code...`
<file:connector name="File" writeToDirectory="${file.outpath}" autoDelete="true" outputAppend="true" streaming="true" validateConnections="true" doc:name="File"/>
<flow name="FileReadingFlow">

Hi, You need to convert the payload to a COLLECTION TYPE OBJECT before the batch reference call. So adding Transform Message(%output application/java) before the Batch Reference can do that. Also note that the Splitter in the Batch Input Phase is not executed if your calling the Batch Module via reference call.
