Well, I've got this simplified down a lot. Forget the beaneditform and
apppropertyedit block. Here we go: TestPage.tml has
<t:form t:id="myForm">
<t:flexDateEditor t:id="theDateEditor" flexDate="myFlexDate" />
<br />
<input type="submit" />
</t:form>
I construct a proper FlexDate for myFlexDate in testpage.java. There is no
no-arg constructor for flexdate. Flex date editor looks like this:
public class FlexDateEditor extends AbstractField
{
@Parameter
@Property (write = false)
private FlexDate _flexDate;
@Inject
private Request _request;
@Property
private Date _date;
void setupRender ()
{
_date = new Date();
}
protected void processSubmission (String elementName)
{
String dateStr = _request.getParameter( elementName );
// setup outbound param value
_flexDate = // constructor using dateStr.
}
}
<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<t:datefield value="date" />
</t:container>
Question now is what elementName is given. It's not in the params. I don't
think extending abstractfield causes a problem.
