I don't know how can i post value without T, in spring web flow

that's the code:

<form:input id="horaSalidaFin" path="horaSalidaFin" />
<script type="text/javascript">
Spring.addDecoration(new Spring.ElementDecoration({
elementId : "horaSalidaIni",
widgetType : "dijit.form.TimeTextBox",
widgetAttrs : {
required : true,
style: "width:60px",
constraints: {
timePattern: 'THH:mm:ss',
clickableIncrement: 'T00:15:00',
visibleIncrement: 'T00:15:00',
visibleRange: 'T01:00:00'
}
}
}));
Spring.addDecoration(new Spring.AjaxEventDecoration({
elementId: "horaSalidaIni",
formId: "dateForm",
event: "onchange",
params: { _eventId: "updateEntries" }
}));
</script>

This is the generated input that post value with T:

<input type="hidden" name="horaEntradaIni" value="T10:30:00">

And the debuged error:

2012-02-28 11:04:12,409 [http-bio-8089-exec-9] DEBUG org.springframework.binding.mapping.impl.DefaultMa pping - Adding mapping result [TargetAccessError@2ee2f388 mapping = parameter:'horaSalidaIni' -> horaSalidaIni, code = 'typeMismatch', error = true, errorCause = org.springframework.binding.expression.ValueCoerci onException: Value could not be converted to target class; is a suitable type converter registered?, originalValue = 'T11:15:00', mappedValue = [null]]

Thanks a lot.
