Hi,
I would like to get records from DatasourceEntity from lookup and update 2 fields on Customer Entity using javascript.
1. I Created new entity: DatasourceEntity with 3 fields: Name, FiledA, FieldB.
2. I add lookup to DatasourceEntity and add on the form Customer Entity extra field FieldA and FieldB.
3. I created webresource with my code:
function new_copydata(){
var Field1= Xrm.Page.data.entity.attributes.get("new_name").getValue()[0].name;
Xrm.Page.getAttribute("new_fielda").setValue(Field1);
var Field2= Xrm.Page.data.entity.attributes.get("new_fielda").getValue()[0].name;
Xrm.Page.getAttribute("new_fieldb").setValue(Field2);
}
4. I configure OnChange event on lookup filed(DatasourceEntity )
After onchange event I receive error message:
It doesn`t work. Can someone help me?
TypeError: Cannot read property 'getValue' of null
