I actually got the inner and outer <h:dataTable> to work together. After spending quite a bit of time disecting the code line by line, it turns out that the rendered attribute was the root of the problems. | ex. rendered= "#{scsSectionDefinition.allowCriteria == 'Y'}" | Some of the edit fields include a rendered attribute. Once I removed the rendered attribute, everything works fine. All data is submitted an set properly in the @DataModel component. Now I'm just really baffled why does removing the rendered attributes fix my code. Not to mention I really need to have the rendered attribute for some instances.
