Dear everyone!
I got some strange errors in the logfile of my tapestry deployment
application all similar to this here:
----
[INFO] AppModule.TimingFilter Request time: 3 ms

Corresponding code is:
tml:
----
<t:form t:id="logTransformForm">
<p>
*Step 5:* Should the raw values be log-transformed
before normalisation?
<t:radiogroup t:id="logTransformRadioGroup"
t:value="logTransform">
<strong>Yes:</strong>
<t:radio t:id="logYes"
/>
<strong>No:</strong>
<t:radio t:id="logNo"
/>
</t:radiogroup>
</p>
</t:form>
...
<div id="change_logtransform"
style="visibility:hidden">${ChangeIsLogTransformURI}</div>
----
java:
@Persist
private LogTransform logTransform;
public LogTransform getLogTransform() {
return logTransform;
}
public void setLogTransform(LogTransform logTransform) {
this.logTransform = logTransform;
}
public LogTransform getLogYes() {
return LogTransform.YES;
}
public String getChangeIsLogTransformURI() {
return
resources.createEventLink("ChangeIsLogTransform").toAbsoluteURI();
}
public JSONObject onChangeIsLogTransform() {
if(!request.isXHR()) {
return null;
}
String logTransformStr = request.getParameter("logTransform");
try {
logTransform = LogTransform.valueOf(logTransformStr);
if(logTransform == null) {
return null;
}
}
catch(IllegalArgumentException e) {
return null;
}
return new JSONObject().put("dummy", "dummy");
}

js:
//read out radio group
jQuery("[name=logTransformRadioGroup]").change(function() {
var value =
jQuery('input[name=logTransformRadioGroup]:checked').val();
jQuery
.ajax({
url : jQuery(
"#change_logtransform")
.text(),
data : {
"logTransform" : value,
},
success :
function() {
},
error :
function() {
alert('An error occurred, Could not send/receive data, check ISP if
AJAX is supported/blocked by firewall');
}
});
});
Has this something to do with my ajax call? As you see I associated a radio
button change event with an ajax call to change the value of logTransform
server-side without submitting a form(I used chenille kit @onevent before
but it is no longer working with T5.3 so I created my own js code to handle
this)
I think this is the only different part in my code than the example shown
here:

Thank you very much for your help
