How to work with MultiMapping

[Former Member]

I need to map my message types

source

<PersonInputMessageType>
   <persons>
      <person>
         <name>Test1</name>
      </person>
      <person>
         <name>Test2</name>
      </person>
   </persons>
</PersonInputMessageType>

target

<PersonMessageType>
   <person>
      <name>Test1</name>
   </person>
</PersonMessageType>
<PersonMessageType>
   <person>
      <name>Test2</name>
   </person>
</PersonMessageType>

I created a visual mapping where I mapped fields

pesron->person, name -> name.

The result is

<PersonMessageType>
   <person>
      <name>Test1</name>
   </person>
</PersonMessageType>

What step did I miss?

Hello Sergey,

You could use the removeContexts function in case that there are more than one <persons> tags. I'd suggest the following:

person -> removeContexts -> PersonMessageType,

Constant -> person

name ->name

I have done it. But test shows only one PesonMessageType. Is it OK or test must show PersonMessageType for each person?

There is 1..1 occurrence for PersonMessageType and I cannot change it.

If your PersonMessageType has 1:1 occurence , you cannot get the desire output. You can get only one PersonMessageType node.

Hello Sergey,

You also have to create a mapping

<person> -> <PersonMessageType>

Since in a multi-mapping the occurrence of the result message is set to 0..unbounded, it will not be created automatically (0 occurrences are allowed!!!). By the mapping cited above, you create the same number of target messages, as there are <person> elements.

In addition you also have to take care about the occurrences of the target element <person>. If it's set to 1..1, there is no problem. If it's set to 0..1, please assign a constant to it, to make sure it is built up at runtime.

Best regards

I created a maping person->PersonMessageType,

person->person, name->name

Between what elements do I have to add removeContext function?

I have tried person->removeContext()->person. But It doesn't work.

Target person element has 1 occurrence and source 1..unbounded

Use Remove context between

person->(RemoveContext )->PersonMessageType

since you want to create Personmessage type node as many time as person you have to manage context of Person at root level.

Hi Sergey,

YOu need to use the removeContexts() function.
