Can't edit newly added work item field

Question

I am trying to add a new string field (IterationCompleted) to the bug work item in tfs2010. Using the TFS 2010 power tools I edited the work item adding the new field. This results in the following XML

<FieldDefinition reportable="dimension" refname="DevX.IterationCompleted" name="Iteration Completed" type="String">
  <ALLOWEDVALUES>
    <GLOBALLIST name="Iterations" />
  </ALLOWEDVALUES>
  <ALLOWEXISTINGVALUE />
  <DEFAULT from="value" value="∞" />
</FieldDefinition>

I added it to the form next to some related fields. Here is the relevant XML

<Group Label="Classification">
  <Column PercentWidth="100">
    <Control FieldName="System.AreaPath" Type="WorkItemClassificationControl" Label="&amp;Area:" LabelPosition="Left" />
    <Control FieldName="System.IterationPath" Type="WorkItemClassificationControl" Label="Ite&amp;ration Found:" LabelPosition="Left" />
    <Control FieldName="DevX.IterationCompleted" Type="FieldControl" Label="Iteration Resolved:" LabelPosition="Left" Name="IterationCompleted" />
    <Control FieldName="DevX.Customer" Type="FieldControl" Label="Customer:" LabelPosition="Left" />
    <Control FieldName="DevX.ReleaseNotes" Type="FieldControl" Label="Include in Release Notes:" LabelPosition="Left" />
    <Control FieldName="DevX.Billable" Type="FieldControl" Label="Billable:" LabelPosition="Left" Name="Billable" />
  </Column>
</Group>

It is not involved in the workflow at all.

The problem I'm having is in the form. For new bugs, the field appears as expected and is editable (Iteration Resolved):

For old bugs however, the field is not editable. In fact there is no control at all there to input anything:

I found a similar question with an accepted answer to make sure the field is String and that on the Form the type is set to FieldControl. As you can see I have done that and still get the results I am seeing above. I have successfully added fields in the past and never encountered this problem. Does anyone know what I can do to get this field editable in old bugs?

Answer 1

I came across the same behaviour... Or at least similar...

I had to add default values for all the lists..

When I did not have a default value, any WIT's which had already been created could not have there values set, as it was not a ALLOWEDVAULES LISTITEM...

(Note: This code/XML changes the value of a list depending on the state of the WIT)

Sample:

<FIELD reportable="dimension" refname="GovDept.ActionRequiredTFS" name="Action Reqd TFS" type="String">
    <WHEN field="System.State" value="Proposed">
      <ALLOWEDVALUES>
        <LISTITEM value="Assess" />
        <LISTITEM value="Prioritize" />
      </ALLOWEDVALUES>
      <DEFAULT from="value" value="Assess" />
    </WHEN>
    <WHEN field="System.State" value="Active">
      <ALLOWEDVALUES>
        <LISTITEM value="IA Complete" />
        <LISTITEM value="Impact" />
        <LISTITEM value="Implement" />
        <LISTITEM value="Migrate" />
        <LISTITEM value="Unit Test" />
        <LISTITEM value="Fix Fail" />
      </ALLOWEDVALUES>
      <DEFAULT from="value" value="Impact" />
    </WHEN>
    <WHEN field="System.State" value="Resolved">
      <ALLOWEDVALUES>
        <LISTITEM value="Test" />
        <LISTITEM value="Fix Fail" />
      </ALLOWEDVALUES>
      <DEFAULT from="value" value="Test" />
    </WHEN>
    <ALLOWEXISTINGVALUE />
  </FIELD>
