[Solved] Problem with nullable model values during column binding (2010.2.825)

[Scott]

My data model has several values that can be null.  When trying to bind these to columns in the grid I get the following type of error:

Microsoft JScript runtime error: 'approvedByBillingUser.Name' is null or not an object
function anonymous(data) {
return data.approvedByBillingUser.Name;
}

I'm binding the column using:

columns.Bound(o => o.approvedByBillingUser.Name);

it is possible that o.approvedByBillingUser is null and thus the above error.  Is there anyway to get around this, it make the grid impossible to use if not.  Thanks for any help in advance.

I'm also having this problem with null date values and null integers.

Okay I've updated to the latest version and changed the DateTime.aspx as per mentioned in this thread.  That seems to have fixed the null date issues. However I still have issues when a string is null and the model objects have nested objects.  For instance if my model object is:

public class OfficeCycleModel
{
    public CycleOffice cycleOffice { get; set; }
    public Cycle cycle { get; set; }
    public User approvedByBillingUser { get; set; }
    public User approvedByPayrollUser { get; set; }
}

and the approvedByBillingUser is null and I need to bind one of its members to a column I get an error.

columns.Bound(o => o.approvedByBillingUser.Name).Title("Billing Approver").Width(200);

This is the error popup and the function highlighted in the editor file "anonymous code[dynamic]":

Microsoft JScript runtime error: 'approvedByBillingUser.Name' is null or not an object

function anonymous(data) {
return data.approvedByBillingUser.Name;
}

Is there any fix for handling null sub-objects of the model objects?  This is killing me.
