Hello, who can give me an example, how to use the html:select in conjunction with html:options? I had already defined an ActionForm and JSP like follows. The listing of the option-Elements works fine but not the "reshowing" of the selected elements of the list, because after I have clicked the submit button I've got an IllegalArgumentException (BeanUtils.populate):
java.lang.IllegalArgumentException: argument type mismatch at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39 ) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.commons.beanutils.PropertyUtils.setSimpleProperty(PropertyUtils.j ava:1789) at org.apache.commons.beanutils.PropertyUtils.setNestedProperty(PropertyUtils.j ava:1684) at org.apache.commons.beanutils.PropertyUtils.setProperty(PropertyUtils.java:17 13) at org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:1019) {...} My FormBean looks like this: {...} public final class RoleEditForm extends ActionForm { {...} public void setAllUsers(ArrayList allUsers) this.allUsers = allUsers; } public ArrayList getAllUsers() return this.allUsers; } {...}} The allUsers list contains user objects. The user objects have the accessor methods getId(), getName(). My JSP looks like this: <html:form action="/formRole" method="get"> <html:select property="allUsers" multiple="true"> <html:options collection="allUsers" property="id" labelProperty="name" /></html:select> <html:submit/> </html:form> After clicking the submit button I've got the Exception. That's wrong? Thank you very much!
