I'm trying to fill <aura:attribute name="selectedQuotation" type="salesTool.Quotation__c" /> in any way that could works

Filling it with default value compile (means i can save the file)

default="{ 'sobjectType': 'salesTool__Quotation__c',
'Name': 'Test',
'Id':'',
'salesTool__Contact__c':'',
'salesTool__Package__c':'',
'salesTool__Signed__c':false,
'salesTool__Site__c':''
}"  

But a "Uncaught Error: ComponentDef Config required for registration" Error is raised in browser logs at runtime. The folloing demonstration example works well for me :

<aura:attribute name="newExpense" type="salesTool.Expense__c"
default="{ 'sobjectType': 'salesTool__Expense__c',
'Name': '',
'salesTool__Amount__c': 0,
'salesTool__Client__c': '',
'salesTool__Date__c': '',
'salesTool__Reimbursed__c': false
}"/>

But my case is different in a way i use lookupFields and not only literals.

Filling it with an instance of myCustomObject through application event result in an other error. As it seems my aura:attribute is empty at the initialisation of the component, the variable last in a aura source code is null and cause error.

 if (value.auraType === "Component" || !value.isLiteral()) {
            var last = component.lastRenderedValue;
            if (last !== value) {
                var referenceNode = **last**.getReferenceNode();

If somebody have some better experience of lightning, I would appreciate some help ;)

  • Hello, DemoMan, can you add some more details on the bigger picture of what you are trying to do with last.getReferenceNode()? Perhaps one of us can recommend an alternative approach.

You can set a the value of a Lookup field with the Id of the record it references.

For example, if you have a Contact object you can specify a default for the Account lookup, by specifying an Id string for the AccountId field.

<aura:attribute name="newContact" type="Contact"
    default="{ 'sobjectType': 'Contact',
               'LastName': 'Smith',
               'AccountId': '001i000002zxpz1' 
             }"/>

You could also leave it blank and then set it in your JavaScript before calling to your Apex controller.

<aura:attribute name="newContact" type="Contact"
    default="{ 'sobjectType': 'Contact',
               'LastName': 'Smith',
               'AccountId': '' 
             }"/>

And, prior to enqueueing the action set the value explicitly.

var con = component.get("v.newContact");
con.AccountId = '001i000002zxpz1';
action.setParams({
    con: con
});

Or, you could leave it blank altogether and set it in your Apex controller:

@AuraEnabled
public static Contact createContact(Contact con) {
    con.AccountId = '001i000002zxpz1';
    insert con;

    return con;
}

DemoMan, you can set Lookup or Master-Detail field values in the exact same way you would set other sObject fields in Lightning, using component.set(). You can actually create a custom component, and pass the Lookup field as a value to it, in the following fashion:

<salesTool:inputLookupContact value="{!v.quote.salesTool__Contact__c}"/>

You can take a look at this oneContact.app demo I created using a Contact object as the focal point, demonstrating how the Contact.AccountId field is manipulated using a custom ccmt:inputLookupAccount component.

Sorry guys it seems my "Uncaught Error: ComponentDef Config required for registration" was due to a silly error :

Writing this :

{!v.selectedQuotation}

in a component leads to an error when you try to setup the "default" attibute of the aura:attribute element. whatever you set as attribute value.

<aura:attribute name="selectedQuotation" type="salesTool.Quotation__c" default="{ 'sobjectType': 'salesTool__Quotation__c',...}" />

Changing the path {!v.selectedQuotation} to a valid field like : {!v.selectedQuotation.Name} solved the issue
