Selecting more than 28 tickets in version 2.3.2

Hi all!
Few months ago, Torsten Thau helped me with a trick to modify a file -
AgentNavigationBar.dtl - in order to select more than 28 tickets to make
bulk action with them (see email below).
Then I was using OTRS 2.1.5.
Now I'm using version 2.3.2, and seems that the trick doesn't works with
trhis release. Does somebody know if there's any possibility to make
something similar with this version?
Best regards!

But, after having a look at that, i didn't find yet why It's not possible to select more than 28 tickets :(. Can you give me a key? Whats supposed I have to take care?
Sorry, maybe my advice was a little to short. However, at the end of AgentNavigationBar.dtl file you'll find the code-lines which implement the HTML-form, which again keeps the ticket ids of the tickets selected for bulk action. This form can contain only a limited number of ticket ids: #-----------------------8><------------------------------------
