Bug in com.vaadin.data.util.filter.Like.passesFilter(Like.java:64)

Hi.

I have a table with 2 columns (Name, Profession) and it has 10 rows.
In one of this rows the column Name is null.
So, i tried to use the Like class for a filter by Name then i got this error:

Caused by: java.lang.NullPointerException
at com.vaadin.data.util.filter.Like.passesFilter(Like.java:64)
at com.vaadin.data.util.AbstractInMemoryContainer.passesFilters(AbstractInMemoryContainer.java:394)

at com.vaadin.data.util.AbstractInMemoryContainer.addFilter(AbstractInMemoryContainer.java:422)
at com.vaadin.data.util.AbstractBeanContainer.addContainerFilter(AbstractBeanContainer.java:369)

If i put a value or just empty at the null column name, and try to filter again the error does not occur.

Tanks.

The Like filter does not support null values.

If you want to use it and have nulls in your data, use something like And(Not(IsNull), Like) or Or(IsNull, Like), depending on which matches your desired behavior.
