I tried calling a modal window from a controller during an onDrop event. the modal window works (stops user events w/ rest of app) but it allows the drop event to complete before it appears. How can I write it in a way that it stops the onDrop itself (before calling dropClass.dropOnTextWin() below) until the user closes the window? or should I be designing it differently. Thanks for any help! I am calling it like this:

    @Listen("onDrop = #codeBoxWindow #codeBox")
public void onDropDoWrapperCode (DropEvent drpEvt) {

    private void handleDrop (DropEvent evt) {
    if (selectedMultipleItems(evt)) {
            AndOrPlusModal andOrPlusModal = new AndOrPlusModal();
    dropClass.dropOnTextWin(evt, codeBox, titleBox);

and AndOrPlusModal looks like this:

public class AndOrPlusModal {
AndOrPlusModal() {
private void createWindow() {
    try {
        Window win = (Window)Executions.createComponents("/modalOpAfterDrop.zul",null, null);
    } catch (Exception exe) {
        ErrorMessage.showErrorMsg("Failed to open window with operators (and/or/plus...). The error message was: " + exe.getMessage(), 
                "Error", Messagebox.OK, Messagebox.ERROR);

I accomplished this w/ an event. I publish it from the button click in the window made w/ createComponents() and listen for it in the other controller. the listen event finishes the drop. look up eventqueues in the documentation for an example.
