tr:chooseDate Connection failed

Date/time picker tr:chooseDate allows me to select dates and times in the
current month and year, but when I attempt to select other months/years, I
get the following JavaScript error: "Connection failed"

My code:

<tr:inputDate chooseId="mappingDateChooseDate" id="mappingDateInputDate"
label="Mapping Date"
value="#{workItemDescriptionBean.selectedWorkItem.mapping_date}">
          <tr:convertDateTime pattern="yyyy-MM-dd HH:mm:ss"
secondaryPattern="yyyy-MM-dd HH:mm:ss" />
        </tr:inputDate>
        <tr:chooseDate id="mappingDateChooseDate" shortDesc="Mapping
Date"></tr:chooseDate>

Anyone know why this is would fail?

Thank you,
