Datetimepicker simple thing doesn't work java.text.ParseException: Unparseable date: ""

Hi All,

I:'ve been battling this for many hours.
I hope someone can help.
Using JDK 1.5, Struts 2.0.11


My property:
shoot_date of type Date
has get and set and on execute()
set's the default date to today's date
setShoot_Date(new Date);

on the form:
<s:datetimepicker name="shoot_date" displayFormat="MM/dd/yyyy" />
even without displayformat it doesn't work.

what happens is that i click the submit button that submits an action 
that executes a method that tries to read the shoot_date and it's null.

Hence the error in my log:

java.text.ParseException: Unparseable date: ""
        at java.text.DateFormat.parse(DateFormat.java:337)
        at 
org.apache.struts2.components.DateTimePicker.format(DateTimePicker.java:309)


Does anyone have a good working example?

Thank you very much,

Serge

Doesn't that need to be theme="ajax"?

Re: Datetimepicker simple thing doesn't work java.text.ParseException: Unparseable date: ""

Here is an example where I use it successfully:

<s:datetimepicker name="incomingAnswer" displayFormat="d MMMM yyyy"
                  dayWidth="wide" formatLength="full" type="date"
                  value="%{defaultAnswerDate}"
                  startDate="%{tomorrowAsRFC3339}"
                  required="true"/>

but in this specific case defaultAnswerDate, startDate and 
incomingAnswer are all String properties whose values are in RFC3339 
format ("yyyy-MM-dd").
This doesn't account for the blank error you're experiencing.  As Dave 
mentioned, the most likely case for that is a property name mismatch.

Hello Jeromy,

I do have :  <s:head theme="simple" />
Also, i use Netbeans to generate respective get/set method so they are 
JavaBean std compliant.

The issue for me unfortunately is getting the value back , it seems to 
lose it.
:(

Thanks for feedback though.

Serge

Hi Serge,

You'll find many emails in this forum relating to DatePicker problems.  
Some of the solutions are here: http://cwiki.apache.org/S2WIKI/vault.html

In this case though, is it possible you've forgotten the s:head tag at 
the top of the page?

I'm not sure what the JavaBean convention would be for a property with an
underscore.

Have you tried it as "shootDate" (with corresponding
getShootDate/setShootDate methods)?
