Description

A text with a control character.

private String controlFoo = "Deimoyyy\u001Azzz";
public String getControlFoo() {
  return controlFoo;
}

<tc:out id="ajaxOut" label="Controlfoo" value="#{controller.controlFoo}"/>
<tc:button label="Ajax">
  <f:ajax render="ajaxOut"/>
</tc:button>

The page is rendered properly if execute a full page reload.
If pressing the ajax button, this 'ajaxOut' component is not rendered. You can find the control character in the ajax response.

Please note, the error is not only for the 'value' attribute. It also appears for the 'tip' attribute (and probably for all other string attributes).
