I'm not sure if this sentence is correct.
(Terms written as
SpreadFilter are technical terms so don't bother with them.)
I fixed an error that caused the
throw a NullPointerExceptionwhen the filter was reset.
I'm unsure wheter it is
... when the filter was reset.
... as the filter was reset.
... when the filter has been reset.
... as the filter has been reset.
What I want to say is:
There is a filter and everytime a user clicked the reset button, the filter
throw a NullPointerException. This is now fixed.
