Thank you for submitting this cool story – Trackback from JavaPins…

Please take a look at this example:
http://loianegroner.com/2010/05/how-to-populate-ext-js-combobox-using-spring-controller/

Thanks!

var formatStore = new Ext.data.Store({
proxy: new Ext.data.HttpProxy({
url: ‘selectAllFormats.html’,method:’GET’
}),
reader: new Ext.data.JsonReader({
root:’formats’
},
[{name: 'formatId'},
{name: 'formatDcscription'}
])
});

items: [
{
xtype: 'label',
width: 160,
text: 'Format:'
},
new Ext.form.ComboBox(
{
id: 'formatCombo',
waitMsgTarget: true,
name: 'formatList',
valueField: 'formatId',
displayField: 'formatDcscription',
store: formatStore,
editable: false,
typeAhead: true,
//hiddenName : 'formatType',
mode: 'remote',
anchor: '100%',
//allowBlank: false,
//multiSelect: true,
//renderTo: 'multiSelectCombo',

// autoLoad:true,
emptyText:'Select a format...',
//triggerAction: 'all',
//onTriggerClick:function()
//{
//getFormat(formatStore);
//},
forceSelection: false ,
selectOnFocus:true
})
]

@RequestMapping(value=”/selectAllFormats.html”, method = RequestMethod.GET)
public @ResponseBody Map loadFormats() {

HashMap<String, List> modelMap = new HashMap<String,List>();
modelMap.put(“formats”, formatJsonService.getAllformats());
System.out.println(“Model Map==”+modelMap);
System.out.println(“Formats==”+modelMap.get(“formats”));
System.out.println(“Format Id==”+modelMap.get(“formats”).get(1).getFormatId());

return modelMap;
}

the above is the flow..please revert back to me..with the solution..

}

and data has the department , graphDataMap list

know how to set department list to jsp’s for each loop

I’m having some trouble with jsonView.

My problem is the browser is attempting to open the json results as a file, rather than calling the JQuery success function.

I am new to JQuery and JsonView – so I’m not sure if i’m missing something.

Here is my ajax call:
$(‘#appForm”‘).ajaxForm(
{
type: ‘POST’,
target: ‘/app/testSubmit.json’
}
);

Here is my controller:

@RequestMapping(“/testSubmit.json”)
public ModelAndView testSubmit(HttpServletRequest request,
HttpServletResponse response, AppCommand command)
throws ServletException, IOException {

Map model = new HashMap();
model.put(“success”, true);
return new ModelAndView(“jsonView”, model);

}

Here is my views.xml:

So basically it goes into the correct method in the controller, and then returns a jsonView which in turn attempts to open the result as a json file with the correct model data within the browser.

Any tips where I’m going wrong ?
Thanks,
Lisa

Iam adding my jsonObject to the ModelAndView and returing it.
modelAndView.addObject(cust.toJsonObject()); The json structure is changing because of this and Im not able to traverse properly in the java script.

Somehow the above text was missing from my previous posting.

When you instantiate ModelAndView in the controller you can do
ModelAndView  modelAndView = new ModelAndView(“jsonView”);

May I know, what does the

[modelMap.put("rows", service.generateColumns());]

service.generateColumns() looks like?
