J2MEPolish cannot compile example application

I want to compile J2ME Polish example application "Blank" for "Nokia/Series60E3" device. I get a compile error. What am I doing wrong?

It seems there is accessed private property of parent object, therefore it cannot be compiled. If I try to compile it for "Generic/AnyPhone" device, it works OK.

It seems like a bug in SourcedLazyContainer class. They refer to the lastPointerPressY and lastPointerPressYOffset fields, which are only available when the device has pointer events. They are defined in the Container class like this:

//#ifdef polish.hasPointerEvents
/** vertical pointer position when it was pressed the last time */ 
protected int lastPointerPressY;
/** scrolloffset when this container was pressed the last time */
protected int lastPointerPressYOffset;
/** time in ms when this container was pressed the last time */
protected long lastPointerPressTime;
//#endif

Because the device you are targeting does not have this capability, these fields are not defined. In the case of the Generic/AnyPhone, this capability is defined, and as such, the build succeeds. You can try and add the "hasPointerEvents" capability to your devices.xml / custom-devices.xml file, or set the polish.hasPointerEvents property in your ant target.
