I understand, but p_aukcje is what i received from input control (collection) on Jasper Server and i need Array List from received collection i don't want to initilize it in defaultValueExpression "rigidly", In Jasper Studio in section Preview in parametr p_aukcje i add two values for example and i want to initialize arrays these values :) If you know what i mean

Hi, I use Jaspersoft Studio, i wanted use collection parameter, i do it in this way: <parameter name="p_aukcje" class="java.util.Collection"> <defaultValueExpression><![CDATA[Arrays.asList()]]></defaultValueExpression> </parameter> When i wanna use collection parameter in query like this : where $X{IN, o.aukcja_id, p_aukcje} my parameter p_aukcje is null, anyone help? But when i display it using textField it is ok, but i query is null
