eu vi um exemplo onde tem dois beans.
no JSP o exemplo tinha o comando new testList
e esse testlist tem dentro dele um new listObject.
poderia eu usar isso tb? quero colocar tal valor em tal coluna eu teria como fazer isso? usando esse raciocínio?
passar atravez d bean os valores pro grid.
segue abaixo os 2 bean;
TestList
