I have defined a variable to keep application/json collection.
<set-variable value="#[payload.'IntegrationEntities'.'amendmentId']" doc:name="AmendmentIds" doc:id="03b6c46a-fc7b-43d4-b23a-502146ef0b13" variableName="amendmentids"/>
<logger level="INFO" doc:name="Logger" doc:id="6a1ad892-65f9-4dd2-9891-bdf3ad64c908" message="#[vars.amendmentids]" />
It prints as;
[
"8a9a84b76b5a5a59016b687bae35012e",
"8a9a84b76b5a5a59016b6888e90e0144"
]
Then I use ForEach loop to define few process logic for each Id,
Within foreach loop how I can get, each above id?
I used,vars.amendmentids[vars.counter]], but getting following error[1]
<foreach doc:name="For Each" doc:id="7b741315-aa28-4704-82f0-629c21d93853" collection="#[vars.amendmentids]">

</foreach>

you need to access the payload only in foreach scope:
<foreach doc:name="For Each" collection="#[vars.amendmentids]">
<logger level="INFO" doc:name="Logger" message="#[payload]"/>
</foreach>
As in foreach each element of your collection will be the payload.

I have defined a variable to keep application/json collection.
My original payload contain following json block;
"amendments": {
"amendmentId": ["8a9a84b76b5a5a59016b687bae35012e",
"8a9a84b76b5a5a59016b6888e90e0144"]
}
<set-variable value="#[payload..amendmentId[1]]" doc:name="AmendmentIds" doc:id="03b6c46a-fc7b-43d4-b23a-502146ef0b13" variableName="amendmentids"/>

I fixed it by defining output mime type like;
<logger level="INFO" doc:name="Logger" doc:id="049c3137-2f92-4077-8e3f-b26516cc5528" message="#[output application/java --- vars.amendmentids[vars.counter - 1]]"/>
This is my ArrayList -
[
{
AccountNumber=123456,
Amount=257710.06
},
{
AccountNumber=845679,
Amount=3672351.06
}
]
Here, I want to check whether the account number 123456 is in the list or not.
I have used "Choice" component, because I want to create another list with searched account numbers. This is my code-
<choice doc:name="Choice">
<when expression="#[flowVars.investOneList.contains(123456)]">
<logger message="Account number is present" level="INFO" doc:name="Logger"/>
</when>
<otherwise>
<logger message="Account number is not present" level="INFO" doc:name="Logger"/>
</otherwise>
</choice>
Here, my logger prints "Account number is not present". My code is not able to find the account number, although it is there in the list.
Could anyone please help me out?
Thanks!
If you want to use List.contains(...) you will need to map the variable you have like this:
%dw 1.0
%output application/java
---
flowVars.investOneList map $.AccountNumber
Which will output [123456, 845679] as the payload (you can set to something else if you want). Then you can do this in your choice router:
<choice doc:name="Choice">
<when expression="#[payload.contains(123456)]">
<logger message="Account number is present" level="INFO" doc:name="Logger"/>
</when>
<otherwise>
<logger message="Account number is not present" level="INFO" doc:name="Logger"/>
</otherwise>
</choice>
But you could do the whole thing in MEL by using the dw() function like this:
...
<when expression="dw('(flowVars.investOneList map $.AccountNumber) contains 123456')">
...
And that will prevent you from needed an intermediate calculation just to get a list of the account numbers.
I have a case, where I have to log the exception error in an object in Salesforce, where I have to also take the payload (the record) for which error is there. The error here will be the record level error and I am using a batch process for this. In the screenshot there is how we are processing the exception.
Following is the xml
<batch:step name="HandleFailedRecords_AccountSF-360" accept-policy="ONLY_FAILURES">
<set-payload value="#[getStepExceptions()]" doc:name="Set Payload"/>
<foreach doc:name="For Each" collection="#[payload.values()]">
<set-variable variableName="Record_level_error" value="#[payload]" doc:name="Record_level_error"/>
<dw:transform-message doc:name="Transform Message" metadata:id="9c2e408a-f530-4ffd-a205-a787c8bc94b2">
<dw:set-payload><![CDATA[%dw 1.0
%output application/java
---
payload map
{
SF_Object_Type__c: "Account"
}]]></dw:set-payload>
</dw:transform-message>
<sfdc:create config-ref="Salesforce__Basic_Authentication" type="Exception__c" doc:name="Salesforce">
<sfdc:objects ref="#[payload]"/>
</sfdc:create>
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
<!-- <flow-ref name="HandleRecordFailure" doc:name="HandleRecordFailure"/> -->
</foreach>
</batch:step>
</batch:process-records>
Here I am able to get what exception I am getting, but what else I need is for which value it is getting errored out.
Bast way to handle properly exception handling in batch processing is to do a flow-ref to a normal flow with his proper exception handling, there you will be able to handle your exception in a standard mule way and do what you need in the exception catch flow.
Hope this helps

I'm trying to initialize a map with the following in a mule expression-component:
#[message.payload = [ 'changeSet' : #[payload], 'sourceAndConnectionMap' : #[flowVars['sourceAndConnectionMap']]]]
Based on the following page, this looks okay, but does not work.
https://developer.mulesoft.com/docs/display/current/Mule+Expression+Language+Reference
Only the first key is set ('changeSet'), and for some reason the payload, which is a map, becomes an ArrayList containing a map... I can also initialize this with just the second key and valy, so I know there isn't an issue resolving the flowVar.
Is there something basic about how I am initializing this map that is incorrect?
In MEL a map should be created like:
#[{'key':'value', 'key1':'value1'}]
If you do
#[[]]
That's just a list of elements.
The other comments, if you're already inside a:
#[]
You need not to add it again. In your example you have it several times.
Please run this through the Mule debugger (put brakepoints in the logs)and you'll see the difference.
<flow name="test>
<set-payload value="#[{'key':'value', 'key1':'value1'}]" doc:name="Set Payload"/>
<logger level="INFO" doc:name="Logger"/>
<set-payload value="#[{'key':'value', 'key1':payload}]" doc:name="Copy_of_Set Payload"/>
<logger level="INFO" doc:name="Copy_of_Logger"/>
<set-payload value="#[['key','value', 'key1','value1']]" doc:name="Copy_of_Set Payload"/> <logger level="INFO" doc:name="Logger"/>
</flow>

I have route choice depending on the payload. The payload can be either list, map or string. The payload has to be identified and routed depending on the payload type.
I think that you want something like that
<choice doc:name="Choice">
<when expression="#[payload is List]">
<logger level="INFO" message="i am list" doc:name="Logger"/>
</when>
<when expression="#[payload is Map]">
<logger level="INFO" message="i am map" doc:name="Logger"/>
</when>
<when expression="#[payload is String]">
<logger level="INFO" message="i am string" doc:name="Logger"/>
</when>
<otherwise>
<logger message="class doesnt match with [list, map, string]" level="INFO" doc:name="Logger"/>
</otherwise>
</choice>
I do agree with Eddú response, except for that I would add an otherwise path. If you don't do that and get something different than a list map or string you would get the rather cryptic error:
org.mule.api.routing.RoutePathNotFoundException: Can't process message because no route has been found matching any filter and no default route is defined. Failed to route event via endpoint: ChoiceRouter [flow-construct=testNull, started=true]. Message payload is of type: NullPayload
