If I use first "edit window", and after "add window", due to "edit window" is bigger, add window opens with height = 900, no 500. And if  I use first "add window", and after that "edit window", when "edit window" opens its size is only of height = 500. How could I do that each modal window have its correct size?

Heres is my code:

jQuery("#listadoGrid").jqGrid({

url:'/AODB2/realTime/arrivalFlight/NewArrivalFlight.action?accion=listar&selectedPage='+paginaSeleccionada,

datatype: "json",

colNames:[ "<s:text/>",
