Prefill multi lookup fields

Hello,

I believe that this example will help you with your task.

In there in the method onEntityInitialized and onwards we are setting values for some columns. At that point, you should have a "doesn't exist" error.

Here is the solution:

attributes: {
	//multiLookup Feld "Contract"
	"ContractClient": {
		"caption": {"bindTo": "Resources.Strings.Client"},
		"dataValueType": this.Terrasoft.DataValueType.LOOKUP,
		"multiLookupColumns": ["Account", "Contact"],
		"isRequired": true,
		"dependencies": [
			{
				  "columns": ["ContractClient"],
				  "methodName": "onContractClientChange"
			}
		]
 
	},
 
	//multiLookup Feld "InvoiceRecipient"
	"InvoiceRecipient": {
		"caption": {"bindTo": "Resources.Strings.InvoiceRecipient"},
		"dataValueType": this.Terrasoft.DataValueType.LOOKUP,
		"multiLookupColumns": ["InvoiceRecipientContact", "InvoiceRecipientAccount"],
		"isRequired": true
	}
}
 
methods: {
	onContractClientChange: function(argument, field) {
		const contactClient = this.get("ContractClient");
 
		if (!Terrasoft.isEmpty(contactClient)) {
			const invoiceRecipient = {
				column: contactClient.column,
				value: contactClient.value,
				displayValue: contactClient.displayValue
			};
			this.set("InvoiceRecipient", invoiceRecipient);
 
			if(contactClient.column == "Account") {
				this.set("InvoiceRecipientAccount", contactClient);
			}
			if(contactClient.column == "Contact") {
				this.set("InvoiceRecipientContact", contactClient);
			}
		}
	}
}
