Display processing popup.

[unknown-user]

Is it possible to display a "Processing, please wait" popup?
I have defined a custom action that can take a little time to
complete and I would like to display some type of indicator to
the user that it is still running.
This could be like the "Site is being created…" popup
that is displayed when a new site is being created.

I updated the onActionSimpleRepoAction function in actions.js
to include:

// Execute the repo action
Alfresco.util.PopupManager.displayMessage(
{
  text: "Please wait…",
  spanClass: "wait",
  displayTime: 0
});
