Hello Nico! Once more I have followed your advises. Now the code look like this:
<html:text property="arrayForm(0).name"> <html:text property="arrayForm(1).name"> <html:text property="arrayForm(2).name"> I get the following error message: No getter method for property arrayForm(0).name of bean org.apache.struts.taglib.html.BEAN Do Struts really know, that it has to call the method "testForm.getArrayForm(i).getName()" ???? You know it is an Array of Benas inside an Form. Regards, Arne > -----Ursprüngliche Nachricht----- > Von: Nicolas De Loof [mailto:[EMAIL PROTECTED] > Gesendet: Mittwoch, 2.
