XT Ajax XT.doAjaxSubmit problem

[doyles]

Hi

I am having problems getting doAjaxSumit to work as I keep getting:

UnsupportedEventException: Cannot handling the given event with id: loadBaseAssets

I have successfully used XT.doAjaxAction in my app and everything is ok. I wanted to call an event handler after the form submission which in fact I had already called successfully by doAjaxAction. Its probably a configuration error, but I can't see it.

Here is my code:

Spring config:

<bean id="fxstrikeoptimizerController" class="com.barcap.fx.web.controller.FxStrikeOptimizerController">
        <property name="sessionForm"><value>true</value></property>
        <property name="commandName"><value>strikeOptimizeCommand</value></property>
        <property name="commandClass"><value>com.barcap.fx.bus.command.StrikeOptimizeCommand</value></property>
        <property name="validator"><ref bean="strikeOptimizeValidator"/></property>
        <property name="formView"><value>strike</value></property>
        <property name="successView"><value>ajax-redirect:/strike.do</value></property>
        <property name="cmd">
            <ref bean="strikeOptimizeCommandBean"/>
        </property>
        <property name="webservice">
            <ref bean="fXStrikeWebService"/>
        </property>
    </bean>

<bean id="ajaxInterceptor" class="org.springmodules.xt.ajax.AjaxInterceptor">
    <property name="handlerMappings">
        <props>
            <prop key="/strike.do">ajaxStrikeHandler</prop>
        </props>
    </property>
	</bean>

My ajax handler class contains multiple handlers all of which work when called by a doAjaxAction, but when I try to call one of them with

XT.doAjaxSubmit('loadBaseAssets', this);

I get the following exception

Hi Steve,

sorry for the late reply, I've been away.

Please can you post your HTML/JSP code, plus your Ajax handler code (at least your methods signatures)?

Thanks,
Cheers,

Hi Sergio,

Thanks for coming back.

Here is my handler code

public AjaxResponse loadBaseAssets(AjaxActionEvent event) {
		
		logger.info("loadBaseAssets- Start");
						
		String assetVal=(String)event.getParameters().get("asset");
		logger.info("asset = "+assetVal);
		
		StrikeOptimizeCommand cmd=(StrikeOptimizeCommand)event.getCommandObject();
		String baseAsset=cmd.getBaseCCY();
		logger.info("base = "+baseAsset);
				
		// Create the component to render (a list of html option elements):
        List options = getBaseAssetOptions(assetVal,cmd);
        logger.info("new base = "+cmd.getBaseCCY());
        event.setCommandObject(cmd);
                       
        // Create an ajax action for replacing the content of the "baseAssets" element with the components just created: 
        ReplaceContentAction BaseAssetsAction = new ReplaceContentAction("baseAssetsId", options);
                    
        // Create a concrete ajax response:
        AjaxResponse response = new AjaxResponseImpl();
        // Add the actions:
        response.addAction(BaseAssetsAction);
                    
        logger.info("loadBaseAssets- end");
        return response;
	}

and JSP fragment:

<form:select path="baseCCY" id="baseAssetsId" 
				      			onchange="XT.doAjaxAction('loadMarketSpot', this, {'asset':assetId.value,'base':baseAssetsId.value,'tenor':tenorId.value});"
				      		 >
				      		<form:option value="Please Select"/>
				      		<form:option value="EUR"/>
				      		<form:option value="GBP"/>
				      		<form:option value="USD"/>
				      		<form:option value="AUD"/>
				      		<form:option value="CHF"/>
				      		<form:option value="CAD"/>
				      		<form:option value="JPY"/>
				      	</form:select>

cheers

forgot here is the submit code


function submitStrikeForm()
{
//document.strikeForm.submit();
var selectedAsset=document.getElementById("assetId");
XT.doAjaxSubmit('loadBaseAssets', this, {'asset':selectedAsset.value});
}

[sbtourist]

Here is my handler code

public AjaxResponse loadBaseAssets(AjaxActionEvent event) {

[CUT]

It has to be:

public AjaxResponse loadBaseAssets(AjaxSubmitEvent event) {

Methods handling submit events must have an AjaxSubmitEvent parameter.

Let me know.
Cheers,

My application is using spring MVC + Spring Webflow and in that case when i am going to reder a flow which is using ajax the application timeout occurs and i am handling the exception occured during timeout in flow handler . During this exception i am trying to redirect the flow to the default flow within Abstractflow handler using the following code.
public String handleException(FlowException flowException, HttpServletRequest request, HttpServletResponse response) {
Exception exception = (Exception)findRootCause(flowException.getCause()) ;
String errorCode = null;
if (flowException instanceof NoSuchFlowExecutionException) {
BookingException bookingException=new BookingException(flowException);
bookingException.setErrorCode("flow.invalid");
request.setAttribute(WebKeys.BUSINESS_ERROR,bookin gException );
if(request.getRemoteUser()!=null){
request.getSession().invalidate();
return "/ibe/login";
}else{
request.getSession().invalidate();
return "/ibe/booking";
}

In the normal flow it gets redirected to the given url but in the case of ajax flow its adding &fragments"somename" to the redirected URL so the url becomes "/ibe/login&fragments omename". Why this is happening.

Due to this issue i am not able to render a viw while application timeout occurs in ajax flow.
