Hello!
I've got a question regarding the fieldTrackings of a form delegate.
From my understanding, this is a list of trackings that the delegate
stores. It does contain a tracking entry for each form field that is
being validated. A field tracking may contain the error message
(errorRenderer != null), but it would also be present if the related
form field does validate without any errors. So you can step through
the trackings and display the message next to the input field.
In my example below, submitting the empty form creates field tracking
list with an error for each field, which is the expected behaviour.
But if I enter values into all fields of the form, the field
trackings contains only entries for TextField and DatePicker. There
are no recordings for the PropertySelection and the Checkbox field,
thus you cannot step through the trackings list and display the error
message.
Is this a bug or is this the way it should work?

P.S. I'm using Tapestry 4.0.

<body jwcid="@Body">
<table border="1">

<td><b>fieldName</b></td>
<td><b>component</b></td>
<td><b>input</b></td>

<span jwcid="@For" source="ognl:beans.delegate.fieldTracking"
value="ognl:tracking">

<td><span jwcid="@Insert" value="ognl:tracking.component"/></td>
<td><span jwcid="@Insert" value="ognl:tracking.input"/></td>
<td><span jwcid="@Insert" value="ognl:tracking.errorRenderer"/></td>

</span>
