Date and Time as Combo Boxes

[Aaron Ong]

I am trying to have 6 Combo Boxes for Date/Time(date, month, year, hours, minutes, seconds) using IBM Rational Software Architect.
I have each combo box's value bond to a bean with GregorianCalendar : #{stockData.stock.intakedt.time.date}. However, I kept receiving "Error testing property 'date' in bean of type null".

Appreciates rapid help; project's due tomorrow.

intakedt.getTime() returned null.

Just make sure that it doesn't. Instantiate it.

How do I do so?
From the JSP page it is being used, the pagecode or the bean?

[Bauke Scholtz]

Uh, just in the bean where it comes from?

Are you using a visual editor or so? I highly recommend you to stop with that until you understand the autogenerated code and are able to write it yourself without help of the visual editor.

Sorry for being an idiot...
My bean instantiates a class named Stock, which contains all the attributes.

I guess I am...

[Bauke Scholtz]

intakedt.getTime() should never return null. That's all. In the bean class behind 'intekedt' you need to instantiate the 'time' property. You can do it in the constructor or already in the instance variable declaration.

Thank you for your time and patience!

Er, another problem although the previous one is solved.
With the 6 combo boxes, and
"public StockData(){
getStock().getIntakedt().setTime(new Date());
}"
in the bean, the page is still not able to do database calls, or maybe even accessing the code behind the button(I'm using JPA).
Am I doing something wrong?
