tmongodbinput could not read from Mongo document with array field
Hi,
I could not able to ready mongo array sub-fileds using tmongodbinput. Here is the document , i am trying read. Of this mongo document, I can read StartEvent and EndEvent fields like account_id and end_cause easily. But for fields like report_tag and report_data, i get Exception. Is there a way to read the array fields using tmongodbinput or some other talent components.
{ "_id" : ObjectId("5155a6c3c2e6a95fd5c7d25a"),
"StartEvent" : { "Timestamp": NumberLong("1361769140226"),
"account_id" : "1",
"version" : "2.9.0" },
"EndEvent" : { "timestamp" : NumberLong("1361769164773")
"end_cause" : "terminated" },
"Details" :
}
Exception in component tMongoDBInput_1
java.lang.IllegalArgumentException: BasicBSONList can only work with numeric keys, not:

i downloaded a component off of the talend exchange name tJsonNormalize. i did a tmap off of this to a tPivotColumnDelimited then off that csv i was able to tmap to the output component.
I am too having the same problem. I cannot retrieve array sub-fields using tmongodbinput. It will be very useful if anyone suggest me answer. I am not getting any error. Rather no values are displayed while using dot operator to represent array of fields.
I am having the same problem. Did anyone fix this issue ?
I have that kind of json structure in my mongo collection :
{
"id":"1",
"name":"John",
"addresses" :
}
I want to have an output row like :
Is that possible ?
Thanks !
