------------------------------------
Jay,
- ... Also can you reproduce if you use a4j:ajax? Yes, I can reproduce it if I use the
RichFaces tag a4j:ajax
- ... Can you produce across browsers? Yes, I can produce it across browsers. The problem
was reproduced by using the browsers: firefox 4.1, IE8 and chrome 8.
Meanwhile I have already identified the cause of the problem. Namely:
The focus handler implementation may not be comprehensive and should be improved. If the
component select does not lose the focus, while various items are selected, it will cause
the focus value is not always updated and that is the reason then, why is this AJAX
request is not triggered by event 'selectitem' (probably more events). The
following code snippet shows from select.js what I mean:
selectitem call:
if(this.focusValue != this.selValueInput.val() ) { // NOTE only if not equal
this.invokeEvent.call(this,"selectitem", document.getElementById(this.id));
}
focus-handler-implementation
__focusHandler: function(e) {
if (!this.focused) { NOTE !!!: if you do not lose the focus of the component, what
then? The focusValue will not be updated and the event will not be invoked !
if(this.__getValue() == this.defaultLabel) {
this.__setValue("");
}
this.focusValue = this.selValueInput.val();
this.focused = true;
this.invokeEvent.call(this, "focus", document.getElementById(this.id), e);
}
},

Key: RF-10948
URL: https://issues.jboss.org/browse/RF-10948
Project: RichFaces
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: component-input
Affects Versions: 4.0.0.Final
Environment: Webcontainer: Tomcat 6
JSF 2.0 implementation: mojarra 2.0.4-b9
Richfaces 4 Final
Reporter: Sergej Becker
Labels: waiting_on_user
The durable usage of the sample below can reproduce an inconsistent behavior of the
component 'select' in conjunction with a standard jsf-tag 'ajax':
on event 'selectitem' (it probably effects more events) the ajax-request
doesn't work consistent. Occurs sporadically! It usually affects the first selected
value.
<h:form id="formid">
<rich:select value="#{...}" label="...">
<f:ajax event="selectitem" render=":formid:tableid" />
<f:selectItem itemValue="0" itemLabel="0..n" />
<f:selectItem itemValue="20" itemLabel="20..n" />
<f:selectItem itemValue="40" itemLabel="40..n" />
</rich:select>
<h:dataTable value="..." id="tableid" var="...">
<h:column>
<h:outputText value="..."/>
</h:column>
<h:column>
<h:outputText value="..."/>
</h:column>
<h:column>
<h:outputText value="..."/>
</h:column>
</h:dataTable>
</h:form>
