When running the showcase with MyFaces, the RowState ace:dataTable example produces the following bug on row selection:

DataTable - Row state:
15-Jan-2013 12:42:26 PM org.apache.myfaces.shared.renderkit.html.HtmlRendererUtils decodeUIInput
WARNING: There should always be a submitted value for an input if it is rendered
, its form is submitted, and it was not originally rendered disabled or read-only. You cannot submit a form after disabling an input element via javascript. Consider setting read-only to true instead or resetting the disabled value back to false prior to form submission. Component : {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /showcase.xhtml][Class: javax.faces.component.html.HtmlBody,Id: __7][Class: javax.faces.component.html.HtmlPanelGroup,Id: __o][Class: javax.faces.component.html.HtmlPanelGroup,Id: __p][Class: javax.faces.component.html.HtmlPanelGroup,Id: __1b][Class: org.icefaces.ace.component.panel.Panel,Id: examplePanel][Class:javax.faces.component.html.HtmlPanelGroup,Id: __1e_6][Class: javax.faces.component.html.HtmlForm,Id: form][Class: org.icefaces.ace.component.datatable.DataTable,Id: carTableRowExpansion][Class: org.icefaces.ace.component.column.Column,Id: cost][Class:org.icefaces.ace.component.celleditor.CellEditor,Id: j_id_1e_29][Class: javax.faces.component.html.HtmlInputText,Id: costInput]}

The input components inside the cellEditors are being decoded (since the selection request was called via ace:ajax render/execute @this where @this is the table), however this request didn't submit the values of those fields to the server.

This would appear to be a bridge or MyFaces shortcoming as I'd expect the submission of the ace:dataTable to include the values of all child inputs.
