WebFlow - bug when working with RichFaces components inside a popup

When rich:calendar is included in a page, some tags <script src="....calendar.js' /> are included automatically so the JS for the calendar can be loaded.

But if the calendar is in a popup view, these JS files (also css, etc) are not included and the calendar is not working. I believe the same issue happens with any kind of richfaces component inside a popup.

As explained in the forum, we could set up a workaround: The rich:calendar component should be loaded an hidden in the main page calling the pop-up. main page. In that case, the JS and css files show properly in the popup.

Even though I'm not 100% sure about it, that issue seems to be related to the WebFlow-RichFaces integration (I haven't found anything on the web that refers to a similar issue when using RichFaces solely).
