Use case B: A button per item
----------
A lot of forms contain lists. It is handy to add one or more buttons to
each item sometimes. (e.g. a 'delete' button for each item in a 
shopping
cart)

I am trying to add an 'edit' action to each member of a Set of child 
objects on a Bean I am working on with JXForms.

public class Coverage extends PersistableBean {
        private String name;
        private String description;
        private Coverage parent;
        private Set children; // this one wants a list of edit buttons
The action needs to be submitted, to the 'forward' continuation.

The Flowscript function looks like this:
(the 'exit', 'save' and 'editParent' commands are working)
function editCoverage (xform, reg) {
  while (true) {                                                // event handling loop
    xform.sendView ("/coverage/edit.xml");
    var coverage = xform.getModel();
    var command = xform.getSubmitId();
    if (command == "exit") {
      break;                                            // don't save, exit
    } else if (command == "save") {
      reg.saveCoverage(coverage);               // save and carry on
    } else if (command == "editParent") {
      xform.setModel(coverage.getParent()); // switch to parent
      editCoverage(xform, reg);         // recurses, calls sendView()
      xform.setModel(coverage);         // now back to child
    } else if (command == "editChild") {
      var child;                                                // get child ???????? 
how?
      xform.setModel(child);                    // switch to child
      editCoverage(xform, reg);                 // recurses, calls sendView()
      xform.setModel(coverage);         // now back to parent
    } else if (command == "newChild") {
      newChildCoverage(xform, reg);     // calls sendView()
    } else if (command == "delete") {
      deleteCoverage(xform, reg);               // calls sendView()
   } else if (command == "move") {
      moveCoverage(xform, reg);         // calls sendView()
   }
    if (coverage == null) break;
    if (reg = null) {
      xform.sendView ("/coverage/fatal.xml");
      break;
    }
  }
}
Has anybody got any ideas how you would identify which child's edit 
button was pressed?



Thanks for any feedback.
