Error when using NEW UI setting in the latest version 07-16

[zaroblan]

I cannot use the New UI setting, the application throws up an exception trace and then eventually dies. I am running the latest Java runtime under Windows 7 (I am a local administrator)

Thanks again for an awesome product and keep up the amazing work guys.

Strange... does the same thing happen with the 07-31 beta?

Code: Select all

if (showCastingCost && !isAnimationPanel && cardWidth < 200) {

This is the line where it breaks, showCastingCost might not have been initialized? Then again, isn't an uninitialized boolean set to false?

[Snacko]

Primitive data types in Java cannot be null. So that error can't happen on this line according to Java specification.

[mtgrares]

class A
{
int a;
boolean b;
}

In a new object:

a is initialized to 0
b is initialized to false

[DennisBergkamp]

Yeah, so what's going wrong? It doesn't make sense

[Rob Cashwalker]

but what if you do this:

A myAObject = null;

[DennisBergkamp]

Right, but these are not objects, they're primitive data types.

[Rob Cashwalker]

but what if the object they were a member of was null? We often create placeholder objects that will be assigned at a later point, but in the meantime, to make the compiler happy about initializing objects, they're set to null.
