JSDO Using Relationship (Angular 2) - ERROR #7211

Hi everyone !

I`m having some issue doing CUD (Create, Update, Delete) using relationship tables.

Everytime I do a request in those operations I get an error: 

ERROR condition: Unable to call SAVE-ROW-CHANGES(). Failed to create query for BEFORE-TABLE. (7211)

Following code:

JSDO Class Update sample code ->

public update(record: progress.data.JSRecord, tableChild?: string) {

let childDataset: progress.data.JSTableRef = this._jsdo[tableChild] || null;

let promise = new Prom ise((resolve, reject) => {

let afterUpdate = (jsdo: progress.data.JSDO, record: any, success: boolean) => {

//ommited return resolve(data)

}

if (this._jsdo) {

this._jsdo.subscribe('AfterUpdate', afterUpdate, this);

if (childDataset) {

childDataset.assign(record)

} else {

this._tableRef.assign(record);

}
this.save().catch((err) => {

reject(err);

});

} else {

throw new Error("JSDO is not initialized.");

}

});

let result = Observable.fromPromise(promise);

return result;

}

Record code service =>

public update(record: any) {

let jsRecord = this.getById(record.Id);

jsRecord.assign(record);

return this._jsdo.update(jsRecord);

}

The Record arg is passing nested elements, but when I get the JSDORecord, just the data without the relationship.

My mainlly question is: I'm not sure what the backend expected as a payload

There's an example available?
