Jahia 4.0.3 addition of field bug

I am running Jahia 4.0.3 build 5580

In an existing container I have defined three new fields, namely:

<content:declareField name='<%="redirectContributorLinkId" + id%>' 
title="Contributed by link ID" titleKey="redirectContributorLinkId" 
bundleKey="<%=resBundleID%>" type="SmallText" />

<content:declareField name='<%="redirectLinkId" + id%>' title="Redirect 
link ID" titleKey="redirectLinkId" bundleKey="<%=resBundleID%>" 
type="SmallText" />

<content:declareField name='<%="redirectSourceLinkId" + id%>' 
title="Redirect source link ID" titleKey="redirectSourceLinkId" 
bundleKey="<%=resBundleID%>" type="SmallText" />

When I try to update an existing container with new values for these fields:

1. If I click on Apply after updating the field, the field changes from 
a html input to text which says 'Value:' without the updated value 
appearing (this is no longer an html input field and cannot be edited). 
  The value is not stored. As an aside, any other fields below this 
field in the update pane also prints out 'Value:' but appended to this 
is the actaul stored
2. If I click on OK the field does not get updated.

If I add a new container, I can updated/edit these fields and they work 
as expected.

Also when I only add one extra field, I am able to update/edit this 
field.  If I subsequently add a second field, the above behaviour is 
exhibited.

Any pointers to the problem?
