What is wrong with this field definition?

Question

This is part of a list definition schema. WHen I try to provision a new list, I get an error when I go to AllItems.aspx page for that list. Thank you!

<Field ID="{2a9ab6d3-268a-4c1c-9897-e5f018f87e64}" Filterable="FALSE" Type="Computed" Name="TeamMemberwMenu" DisplayName="Team Member" DisplayNameSrcField="Team Member" ClassInfo="Menu" AuthoringInfo="TeamMemberwEditMenu" ListItemMenuAllowed="Required" LinkToItemAllowed="Prohibited" SourceID="http://schemas.microsoft.com/sharepoint/v3" StaticName="TeamMemberwMenu">
        <FieldRefs>
          <FieldRef Name="TeamMember" />
          <FieldRef  Name="Custom_x0020_Order" />
          <FieldRef Name="FileLeafRef" />
          <FieldRef Name="FileRef" />
          <FieldRef Name="FSObjType" />
          <FieldRef Name="_EditMenuTableStart2" />
          <FieldRef Name="_EditMenuTableEnd" />
        </FieldRefs>
      </Field>

When I go to AllItems.aspx page, I notice below error in ULS logs.

Error while executing web part: System.NullReferenceException: Object reference not set to an instance of an object.

Answer 1

Can you try removing the following field refs and try again.

	<FieldRef Name="FileLeafRef" />
          <FieldRef Name="FileRef" />
          <FieldRef Name="FSObjType" />

Hi

According to your description, I suggest you create a simple demo with a few fields first. If the demo works, then you can add more fields one by one.

By doing this, it will be easier to find out the root cause of this error.

No luck even after removing the field refs. Any other pointers?

Answer 4

I copy/pasted this list definition from SP 2010 to SP 2013. Do I need to generate new GUIDs for all the fields? Is that the problem?

Answer 5

Hi,

What if you create a simple demo and then add other customization gradually? it will be easier to find out the root cause of the error.

Best regards

Turned out problem was something else. DisplayNameSrcField attribute was pointing to a wrong field.
