use : <html:text property="arrayForm(0).name"> <html:text> is use inside a <html:form>, so it assumes the current bean is the <html:form> form-bean.
Here are general Sruts tags usage : - "name" is the name of a bean in some scope. <html:xx> use form-bean as default and doesn't need this attribute - "property" is the name of the bean property, with indexed / dotted notation - "scope" can be use to define where to search for teh bean. By default all scopes are used to search. - "id" is the name of a script variable / bean in scope that tag creates for you Nico. Hello Nico! I have tríed this with the following code: <html:text property="testForm.arrayForm(0).name"> <html:text property="testForm.arrayForm(1).name"> <html:text property="testForm.arrayForm(2).name"> It resulted in the error: No getter method for property testForm.arrayForm(0).name of bean org.apache.struts.taglib.html.BEAN Regards, Arne > -----Ursprüngliche Nachricht----- > Von: Nicolas De Loof [mailto:[EMAIL PROTECTED] > Gesendet: Mittwoch, 2.
