Hi all,
This one really puzzles me. I have a page with a backing bean and 2 text
input fields: a string and a float. Ajax4Jsf is sending down the changes,
which happen all fine. Now, if I press F5 (refresh) for a few times, the
displayed values will cycle between the old and the newly set values.
Sometimes they are OK, sometimes old, the cycle repeats each 8 clicks on the
refresh and the two values are not wrong at the same time (aka sometimes
only one, sometimes both, but still repeatable).
I don't even know where to start...
I just notice in the console that the getters for the properties are not
always called - are missing precisely when the value is wrong. Below also a
console snippet.
I use MyFaces 1.2.0, Tomahawk 1.1.6, Facelets 1.0.14, Richfaces 3.1.0,
Eclipse 3.3 and Tomcat 5.5.whatever.
Here is the code, I left out the headers and such:
index.xhtml
<a4j:form id="wholePage">
<h:panelGrid
id="tarifZone"
columns="1"
border="0"
cellspacing="0"
cellpadding="0">
<t:column>
<mylib:myGroup />
</t:column>
</h:panelGrid>
</a4j:form>
myGroup.xhtml
<ui:composition>
<h:panelGrid id="myGroup" columns="2" border="1" cellspacing="0"
cellpadding="10">
<t:column>
<t:outputText value="blah" />
</t:column>
<t:column>
<t:outputText value="testfloat" />
</t:column>
<t:column>
<t:inputText value="#{DataAccess.blah}"
title="#{DataAccess.blah}">
<a4j:support event="onchange" ajaxSingle="true"
limitToList="true"
reRender="myGroup" />
</t:inputText>
</t:column>
<t:column>
<t:inputText
value="#{DataAccess.test}"
title="testfloat"
id="testfloat">
<a4j:support event="onchange" ajaxSingle="true"
limitToList="true"
reRender="myGroup" />
</t:inputText>
</t:column>
</h:panelGrid>
<a4j:outputPanel ajaxRendered="true" style="color:red;">
<h:messages></h:messages>
</a4j:outputPanel>
</ui:composition>
DataAccess.java:
public class DataAccess {
private String blah = "1";
private Float test = 1.0F;
public String getBlah() {
System.out.println("---get blah: " + blah);
return blah;
}
public void setBlah(String val) {
System.out.println("---set blah: " + val);
this.blah = val;
}
public Float getTest() {
System.out.println("---get test: " + test);
return test;
}
public void setTest(Float val) {
System.out.println("---set test: " + val);
test=val;
}
}
and console output, with a correct and a wrong refresh:

Thank you very very very much for hinting me what I'm doing wrong...
Regards,
