Hi StackOverflow members!
I have developing custom list in Visual Studio (trough XML). I created list definition (with content type) and added list instance to it.
Here is schema.xml of my list:
<?xml version="1.0" encoding="utf-8"?>
<List xmlns:ows="Microsoft SharePoint" Title="Teams" EnableContentTypes="TRUE" FolderCreation="FALSE" Direction="$Resources:Direction;" Url="Lists/Teams" BaseType="0" xmlns="http://schemas.microsoft.com/sharepoint/">

<Field Type="Boolean" Name="Manager" DisplayName="Manager" ID="{9FC927CC-45EB-4E9E-8F25-18AAEDF7DCAF}" Group="Sample Group" />
</Fields>

and elements.xml with list template and content type:
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<!-- Do not change the value of the Name attribute below. If it does not match the folder name of the List Definition project item, an error will occur when the project is run. -->

<Field Type="Boolean" Name="Manager" DisplayName="Manager" ID="{9FC927CC-45EB-4E9E-8F25-18AAEDF7DCAF}" Group="Sample Group" />
</Elements>
The question is: how to add sample data to this list? Especially to field of type "User"?
I tried to add this code in list instance element like this:
<ListInstance Title="TeamList"
OnQuickLaunch="TRUE"
TemplateType="10000"
Url="Lists/TeamList"
Description="TeamList">
<Data>
<Rows>
<Row>
<Field Name="Employee">CONTOSO\joses</Field>
<Field Name="Manager">true</Field>
</Row>
</Rows>
</Data>
but, error occures: Error occurred in deployment step 'Activate Features': At least one field type in not installed properly. Any help for makeing it work with dialog would be very appreciated.
A User field is a special type of Lookup field. As such, the text value is represented in the format of ID;#TextValue
. And really, it is only the ID that is important. The Value is largely ignored. This can be a problem because while the username will always be the same, the ID that represents that user will change from site collection to site collection.
Your row XML should look something like this:
<Data>
<Rows>
<Row>
<Field Name="Employee">99;#CONTOSO\joses</Field>
<Field Name="Manager">true</Field>
</Row>
</Rows>
</Data>
You said that this is being deployed to an existing site, so you can browse to the User Information page for CONTOSO\joses. The ID will be in the URL's query string. But be aware that even if the feature works in this site, there is no guarantee that the feature will work in other site collections.
To avoid this problem, instead of seeding a list instance using XML, I will generally use a Feature Receiver to pre-populate lists with User fields. I prefer EnsureUser because it will add the user to the site if the user does not already exist.
This will also work:
<Field Name="Employee">-1;#CONTOSO\joses</Field>
In SharePoint 2013 using -1;# to fill a column of type User is less prone to error.
If you misspell or provide a nonexistent user:
<Field Name="Employee">-1;#domain\nonexistent account or misspelled</Field>
The record is NOT created.
Explicitly specifying the ID may result in assigning an existing group or user and could be lot harder to debug. Especially if you also provide a value for the ID column:
<Field Name="ID">1</Field>
<Field Name="Employee">1;#domain\nonexistent account or misspelled</Field>
Both Rich's and Jonathan's answers are correct, just wanted to clarify and couldn't comment due to low rep.
