Application architecture question. Involving Java Spring and EXT Js

[manoj123]

This could be a generic Java and JavaScript related question but just want to see how EXT JS community achieved this kind of functionality.

1. I have a EXT JS web interface which includes forms.
2. Depending on the user interaction, requests are sent to server-side to determine number and type of fields in the form.

At the moment, I have a JSP page which generates JavaScript code (which includes EXT JS components). My form panel will uses JSP url for auto-loader. So far it works fine...however I feel it is a bit dirty implementation. Wondering if there are any better tools/libraries I should be using to achieve this kind of functionality.

Sample JSP code I use:

[<c:forEach items="${entities}" var="entity" varStatus="loop">
                 
        {xtype: 'textareafield',
        id: "<c:out value="${entity.entityid}"/>",
        labeltext:"<c:out value="${entity.entityid}"/>",
        margin: '15 0 0 100',
        value:"<c:out value="${entity.jsvalue}"/>"  
        },
</c:forEach>
