GWT Form data binding

[Jhakda Velu]

Hi All
I'm starting with GWT app and was wondering how we would go about binding form fields to form just like struts . Say i have a Person object which has name age sex Adress ( which itself has addline1,line2 city and country). Say i were to use this for my page and the generic person details like name age etc displayed as a tree node and the adress details displayed on another node. I need to save/ display these. I know how to do this in struts spring etc but not sure about GWT. I do not want to bind each field like a normal servlet/jsp app by getting it using request params. Also, another issue i foresee is that, say a user enters only name and goes to the address node to fill address, once he come back to the first node, the name he entered should be present.

I need a starting point from which i can take off on my own. Starting to look at editors.
Any help on this would be appreciated.

Warm Regards

Hi All
I got the form submit part working. From my form panel, which i named formPanel, all i need to do is to call the submit method.

formPanel.setAction(GWT.getHostPageBaseURL()+ "myGWTApp/testSave");
formPanel.submit();
 

All widgets whose name is set using the widget.setName("shouldMatchAttributeNameOfDTO") matches that of the DTO will get set in the respective attributes. As we used Spring, all i had to do in my controller is to write a method

@RequestMapping(method = RequestMethod.POST, value = "/testSave")
public String testSave(@ModelAttribute("formPanel" ) Person person) {
    // Code to save data goes here
}
 

where Person is the data transfer object.

However, i where i am still stuck is holding the data in my 2 panels. My First panel has generic info about a person like name age etc and the second panel has address details. I am able to save both panels individually, but if i enter data in my first panel and traverse to the address panel, only the address portion gets saved. I also loose the data which i enter in the panel once i navigate to the other panel.

If someone has thoughts on how to do this, i would be most eager to know.

Thanks in advance\
