I have followed a two blogs by Jean Barmash to create a cascading dropdowns in alfresco but due to unavailibility of source code in share.alfresco.com, I am not able to properly understand the blogs.
What I have successfully done so far is, the first blog of filled dropdown by lucene search but not able to understand the code from second blog. Aspecially how the selected country value from one dropdown passed to lucene search to get the cities in other dropdown.
I have implemented cascading dropdown in alfresco explorer and share as well. Refere my Post for share implementation : http://forums.alfresco.com/en/viewtopic.php?f=48&t=37702 If anyone wants code for the above article, can contact me through PM.
