Attached test case that shows issue.

Steps:

• Load welcomeICEfaces.jsf
• Clicking on "Working" button will show output in server logs.
• Clicking on "Broken" button will show nothing.

worth noting that this is only if f:ajax is used- a regular action listener on that button works as expected.

looking through the UIComponentBase implementation of f:ajax events, the components themselves are responsible for state saving the behaviors objects that are attached to them (unclear about when this occurs), rather inspecting the component tree for attached f:ajax component objects. My guess is that this is the failure point that makes this case differ from the plain actionListener case. I am investigating further.

ICE-8459 - Fixed ColumnGroup column children excluded in DataTable visitTree.

Previously only column header facets defined in the header ColumnGroup were rendered, and as such were the only subcomponent visited.

I am adding this comment for the sake of completeness.

The workaround provided above have a limitation. It will not be functional if we need to re-render and execute more then 1 component upon button click.
If you extend <f:ajax /> to <f:ajax execute="@all" render="@all" /> the button will stop working again.
If you reduce it to <f:ajax render="@all" /> the button will work but then we have another problem: Only the button gets executed which means the rest of the viewstate (inputtexts etc.) will be ignored.

To overcome this difficulty the following approach must be taken:

<f:facet name="header">
<h:commandButton value="Broken" actionListener="#

">
<f:ajax render="@all" execute="#

"/>
</h:commandButton>
</f:facet>

In other words instead of using @all in execute parameter of the f:ajax tag you'll need to use id's of the components and/or containers which you need to run through JSF lifecycle. Here fullyQualfiedComponentNames variable will resolve to the following upon bean construction: fullyQualfiedComponentNames = ":myFormId:myComponentId :myFormId:myContainerId:myComponent2Id @this";
