hamad_amaral Field expression not allowed for generic SObject
Hi guys,
When I use the following piece of code I get the error "Field expression not allowed for generic SObject". Can you tell me why even after cast the generic sObject to the correct class I get the error? Is there any solution to get properties from a generic sObject after cast it to a specific sObject type (example an Account or Lead)?
public static void setCode(sObject[] objs){
for (sObject o:objs)
{
if (o.getSObjectType() == Account.sObjectType)
{
o = (Account) o;
}
else if (o.getSObjectType() == Lead.sObjectType)
{
o = (Lead) o;
}
tempCode = generateNewCode(o.Name);
...
Thanks in advance.
You cannot use direct reference or assignment when working with sObjects. Instead you must use their get and put methods.
So instead of
String strObjectName = mySObject.Name;
you need to do:
String.strObjectName = String.valueOf( mySObject.get('Name') );
Same applies to assigning values to sObjects. Instead of:
mySObject.Name = 'MyName';
you need to do:
mySObject.put('Name', 'MyName');

Hmm... is it because you defined o as SObject? like "sObject o"?
Good news! Even though o is SObject type, you can do o.get('Name')! (cast it to String)
