Hello,
I found a problem with the PayloadFactory.
I have the following XML structure generated by an aggregate mediator:
<jsonObject>
<resourceType>Bundle</resourceType>
</jsonObject>
<jsonObject>
<resourceType>Bundle</resourceType>
<entry>
<resource>
</resource>
<resource>
</resource>
<resource>
</resource>
</entry>
<jsonObject>
<jsonObject>
<resourceType>Bundle</resourceType>
<entry>
<resource>
</resource>
<resource>
</resource>
</entry>
<jsonObject>
</jsonObject>
My goal, is to generate a JSON payload like that:
{ "resourceType": "Bundle", "type": "searchset", "entry": [ <my resources
elements here ] }
To do so, I tried many permutation with the PayloadFactory arg evaluator
and I just conclude that this is bugged because the behaviour does not
follow any logic. Here is one of my PayloadFactory permutation:
<payloadFactory media-type="json">
<format>{ "resourceType": "Bundle", "type": "searchset", "entry": $1
}</format>
<args>
<arg evaluator="xml" expression="//entry/*"/>
</args>
</payloadFactory>
And the payload is:
{
"resourceType": "Bundle",
"type": "searchset",
"entry": {
"resource": [
{}, {}, {}
]
}
}
So, I tried with:
<payloadFactory media-type="json">
<format>{ "resourceType": "Bundle", "type": "searchset", "entry": $1
}</format>
<args>
<arg evaluator="xml" expression="//entry"/>
</args>
</payloadFactory>
And I have:
{
"resourceType": "Bundle",
"type": "searchset",
"entry": {
"entry": [
{ "resource": {} }, { "resource": {} } , { "resource": {} }
]
}
}
OK. We are nearly there. So I changed the format of the payloadFactory for:
<format>{ "resourceType": "Bundle", "type": "searchset", $1 }</format>
And I get:
[ { "resource": {} }, { "resource": {} } , { "resource": {} } ]
And I am like "What the hell?" because that is exactly what I wanted for $2
in the previous try (the one with the format { "resourceType": "Bundle",
"type": "searchset", "entry": $1 } ). Where are my custom attributes
(resourceType and searchset)?
Have you got an idea of a workaround for that? I could use a JS mediator
but my payload is so huge that Rhino does not want to compile the script.
Regards,
Thomas
