I am working on ajax using struts 2 frame work.
Application has two text boxes “name” and “age”.
On submitting , those two values should be updated using div tag on the same page itself.
<sx:div id="div2" executeScripts="true" theme="ajax">Value</sx:div>
<sx:submit targets="div2" value="submit">
when i use “targets” attribute in sx:submit ,getting some exception. when i remove “targets” no exception has been thrown.But application needs “targets” attribute to update the div tag.Do i need to any handle exception ?
I am trying this as a sample exmple , my application needs this kind of functionality.
Help me.
Source code as follows :
<%@taglib uri="/struts-tags" prefix="s" %>
<%@taglib uri="/struts-dojo-tags" prefix="sx" %>
<html>
<head><title>Ajax_Div_Tag_Example</title>
</head>
<body><h1>Ajax_Div_Tag_Example</h1><hr>
<sx:div id="div2" executeScripts="true" theme="ajax">Value</sx:div>
<s:form action="resultAction">
<s:textfield name="name" label="Name"></s:textfield>
<s:textfield name="age" label="Age"></s:textfield>
<sx:submit value="submit" targets="div2"> </sx:submit>
</s:form>
</body>

There was a problem with strut2-core-2.jar file.I downloaded latest version and tried.It is working fine now.
