One more change: implement the "Store" operation as a new button in the GUI, and then update the display of the selected item bindings after each store operation.

It looks to me like cell editor Components load data via JSON.get, but that this binding can be overridden. What would really help right now is some feedback on the DataBindingTest (org.apache.pivot.tests). I can't make any sense of it. Thanks, Tom On Feb 8, 2016, at 10:46 AM, Roger and Beth Whitcomb wrote: Definitely row/cell editors use data binding to "load" and "store" values into your TableView data objects. So, the super of your RowEditor will call the "load" method before beginning the edit, and then at the end of the edit will call "store". It is up to you to implement these methods on your bean objects. I should be able to give you a better explanation later today -- have some appointments...

The trick then is to process this information in the TableViewRowEditor, which I have done by creating my own. (I found it difficult to extend Pivot's - basically wound it copying it and renaming it.) My RowEditor can now disable the appropriate CellEditor Component. So far so good. At the moment I am wrestling with understanding TableView data binding. It seemed like I was heading down a path of endlessly extending Components. So far it looks like I can have an "editable" property in a custom TableView cell class (OlympicStanding). I know I can disable CellEditors. Right now the only unknown is how editor Components will bind to custom objects in cells. Let me know if I'm making this more complicated than it is.

A row that's not editable ? I remember a prototype made by a user (but never proposed for a real inclusion in Pivot) to select or render cells in a different way ... do you need something like this ? Anyway we have some example of table row editing, I can give you more details. Note that in our sources in svn (both branch 2.0.x and trunk) there is an example subproject with some not so trivial samples. On documentation I know that could be improved, and any help is welcome :-) ... Note that all our mailing lists are public so you can find many info in some indexing services like Nabble.

I've basically figured out how to display data ini a TableView as "disabled". This basically involves examining the data in context and rendering an appropriate style. So far so good. But once identified as "disabled", how should I go about disallowing editing of the column? That ends my question. Editorial comments follow: I've been wading through the project and so far have been quite impressed. Between the web docs, the API docs, tutorials, examples, demos, tests and source code, there is not much that someone with time and patience can't figure out. Two observations are that many of the examples tend to be very simple and that Google is not much help. Thanks! Tom
