How do I get the values from a selected row.

Question

I am using JDeveloper 9.0.5. On my page, I have placed a button within a table. The button has been assigned an event. The event is within my Action class. This class implements DataAction and has overriden the
processComponentEvents(DataActionContext actionContext);
method.
Question: While I am within the processComponentEvents method, is it possible to obtain the values of selected row?

Good Morning Jeffery,
First off thanks for your clear explanation. I have a few related questions as noted from your response:
There are two ways to communicate the desired model row between the UIX view and the struts controller. One way is to use the singleSelection component in your table and put your buttons in the singleSelection's contents.
When the user selects the radio button for a particular row and then clicks on one the buttons, a built in event handler in UIX will set the current row in the model to be the user selected row. Therefore, your Struts action can operate on the currently selected model row.
When you drop a UIX table from the data control palette it is automatically set up in this way (with a single selection).
Ok, Lets say that i've set everything up as you described. Not lets say that the button was pressed and I hit the overriddenprotected void processComponentEvents(DataActionContext actionContext) throws IOException, ServletException ;
When I look at the request object, I do not see the values. How do I get access to the rowkey at this point?
Some people, however, want to actually render buttons in their table rows, and have those buttons initiate an action on their row. If you are doing this, then you need to pass the row id to your struts action as a parameter, which means that you need to know the row id when you are rendering a button for a given row. There is an EL expression that will return the row-id for the current row, it is:
${uix.current.rowKeyStr}
which is not so obvious or well documented in the preview release (sorry) but should be for the production release.
A generic code snippet would go a long way to shedding some light on that. I guess I am use to using JDeveloper 9.0.3. It seems,"to me", that JDev 9.0.5 has put a completely new twist on things. I find myself wondering when I can use the 9.0.3 syntax and when
should not. If your team has any short source toys around which demonstrated using rowkeys, or accessing the internal parts of the
struts controller, I would find that invaluable. It dose not matter if this information is documented.
Thank you
