I installed awareIM in the evaluation version on Windows and Linux.
I created a bussines object named "name" with one attribute "Name".
I run this new application in testmode and insert a new name "Mueller" into the DB.
I did a query and saw Mueller in the result list.
I user "edit" to change "Mueller" to "Müller" and did a requery and no "Müller" were seen.
Doing a "CSV" export "Müller" is in the result list.
How helps?
Btw: Müller is a common name in Germany.
