NullPointException

[Growiel]

Since I updated to the last version this morning, I have a NullPointerExcecption quite often, as well as widely incorrect analysis of my code.

Here's the exception:

Here's some misshandled code:

USD is NOT a calculated value, it's a simple string. In the same idea, the red-underlined $base_wallet->balance says "Undefined variable amount", which is name of the parameter of the method..

npe fixed in 0.4.4, your screenshot looks more like an issue from somewhere else

[Growiel]

Updating to 0.4.4 fixed both issue. Looks like the npe was having side effects on something else.

Thanks.
