Re: [nebula-dev] NullPointerException with CDateTime (new in 2.4)

[Wim Jongman <wim.jongman@xxxxxxxxx>]

Hi Matthias,

We (Laurent) already fixed this. I will make an intermediate 2.4.1 release for this issue ASAP.

In the meantime you may use the snapshot build.

Cheers,

Wim

Thanks for the new release and in particular  the theming support for various widgets!

Sadly, when switching to the 2.4 in our application (without changing any code)  I instantly ran into a NullPointerException  in the CDateTime widget.

Creating a CDateTime with 

new CDateTime(parent, getStyle() | CDT.DROP_DOWN  | CDT.DATE_MEDIUM | CDT.TIME_MEDIUM | CDT.CLOCK_DISCRETE);

(which worked with 2.3) led to 

 java.lang.NullPointerException
at org.eclipse.nebula.widgets.cdatetime.CDateTime.setBackground(CDateTime.java:2245)
at org.eclipse.e4.ui.css.swt.helpers.CSSSWTColorHelper.setBackground(CSSSWTColorHelper.java:360)
at org.eclipse.e4.ui.css.swt.properties.css2.CSSPropertyBackgroundSWTHandler.applyCSSPropertyBackgroundColor(CSSPropertyBackgroundSWTHandler.java:80)
 
Looks like the picker instance is always null when not using CDT.SIMPLE ...

Best,
  MP
