Ext JS 4 CRUD MVC + Spring MVC 3 + Hibernate 3.5 (Java) example

[loiane]

Hi,

I presented a demo about Ext JS 4 and Java at BrazilJS, a Brazilian Javascript Conference (the biggest JS conference in the world, so far! )

Following is the source code I did a demo at the conference:

Hi,

May I ask your favor?

I had download your demo code and it's so great and helpful, but when i try to do multi-row update (using Ext.grid.plugin.CellEditing) but not working. Any Idea ?

Any ideas how to return json with data where the fields are not lowercase ? Right now I'm getting my all my model properties written with lowercase which is a no go for me :/

Sample :

{"data":[{"name":"Tom","id":8},{"name":"Mike","id":9},{"name":"Jerry","id":10},{"name":"Larry","id":11},{"name":"Tina","id":12},{"name":"Tony","id":15}],"success":true}

In your java model you need to add another import :

import org.codehaus.jackson.annotate.JsonProperty;

and modify the getters :

    @JsonProperty(value="Name")
    public String getName() {
        return name;
    }
