API changed for RecordGrid.withSort

Hi,

today I used the RecordGrid again. I noticed that the method for setting the SortOrder mentioned in the documentation no longer works. Instead of

public Builder<R> withSort(Map<Field<?>, Boolean sort)

there is a method with the signature

public Builder<R> withSort(Map<Field<?>, SortDirection> sort)

In addition, the same code is listed twice: the two code fragments given in Example are the same code as the one given again in the section Sample Code.

I use the following version:

   <groupId>ch.martinelli.oss</groupId>
   <artifactId>vaadin-jooq</artifactId>
   <version>2.1.1</version>

kind regards
Dominik
