Issue with nested CDTs and a!writeToDataStoreEntity

a!writeToDataStoreEntity(
dataStoreEntity: cons!XYZ,
valueToStore: local!xyz,
onSuccess: {
a!save(
local!xyz,
fv!storedValues
)
}
),
a!save(
ri!pqr.id,
repeat(
length(
ri!pqr
),
index(local!xyz, 1, null).id
)
),
a!writeToDataStoreEntity(
dataStoreEntity: cons!PQR,
valueToStore: ri!pqr,
onSuccess: {
a!save(
ri!pqr,
fv!storedValues
)
}
)

We are also trying to do this. Same problem. We will switch back to start a process in background.

Hi Gents,
It is possible to save to nested CDTs using this function.

consider the following CDTs:
w2ds_parent(
pkid (number pk auto),
textfield (text),
w2ds_child (w2ds_child)
)
//

w2ds_child(
pkid (number pk auto),
textfield (text)
)
//

On your submit button, the saveInto syntax is as follows:

saveInto: {
          a!writeToDataStoreEntity(
                    cons!w2ds_parent,
                    'type!{urn:com:appian:types}w2ds_parent'(
                              textfield: local!parentText,
                              w2ds_child: 'type!{urn:com:appian:types}w2ds_child'(
                                        textField: local!childText
                              )
                    )
          )
}

I think the initial question was not about how to save nested CDTs, but how to save two flat CDTs one being parent and the other being child which needs the parent ID. AFAIK this can only be done in two steps.

@Rob...that would work if we had the @OneToMany in the parent cdt.....this limitation makes me think it might be good idea to have nested versions of cdt's as well....for such scenarios
