Dear all,
I feel nervous with the following issue of the getRowData() in ListDataModel. Pls kindly help.
In the bean, there is a property, called "user_list" (ListDataModel), storing the latest result of users from database. Also, there is a property, called "user" (User), storing selected user informaion.
prepareModifyUser() function will update "user" with the selected row of ListDataModel.
public ListDataModel getUser_list() {
return this.user_list;
}
public String prepareModifyUser() {
String fail_msg = "prepare_modify_user_fail", success_msg = "prepare_modify_user_success";
String status = success_msg;
User user = (User)getUser_list().getRowData();
try {
setUser(new User(user.getId()));
} catch (Exception e) {
Logger.log("UserRegistry.prepareModifyUser", e.toString());
status = fail_msg;
}
return status;
}
It is working well to show the list of user on the DataTable. Also, it is sucessfully to call "prepareModifyUser()" by clicking the link on the table, and go to the modify_user page and show all user information.
After the user saved the updated information , the page will be redirect to a modify_user_success page. There is a [back to list] button and [modify again] button only.
When I click the [modify again] button, the system should call prepareModifyUser() again and go to the modify_user page. But, it is fail and there is java.lang.IllegalArgumentException shown. I am sure that I haven't reseted the "user_list".
I am wondering if the cursor in the ListDataModel will be resetted after calling another page? Can anyone help me. Thanks a lot.
brgds,
Daniel
