Ok, error occurs when some document has different field names than previous.
{
_id:"1",
name:"bob",
age:33
}
{
_id:"2",
name:"somename",
age:31
}
{
_id:"3",
status:"X",
somedata:"ABC"
}
TFields "status" and "somedata" are not generated in tdataset?

I have a collection with 10-12 fields. One document has only 1 field (_id). In this case, an error occurs when using DataSet that I got from ToDataset function (SynVirtualDataSet). (I use it in the DBGrid)
Exception:

I have MongoDB collection that contains documents where some fields are sometimes non existing. In that case I want to get a null value.
Using "ToDataSet" to show the result in the datagrid, there is an exception raised (IdemPropNameU).
Also, BSON (synMongoDB) function has a bug, an infinite loop if you specify invalid JSON string e.g. "{something".
