External library failing to work in packaged vf page

Hi
 
I have a functionality (built as a vf page) in which I display all the report folders and the list of reports present in each folder.
The functionality is present in a managed package, hence the code of all the vf pages and classes associated to it are not visible.
I am using Ext js (a js library) to display the above data in a tree structure.
Below code snippet is present at a global level, but isnt getting called when loading the page:
 
<script type="text/javascript">
    Ext.onReady(function(){Createtree();});
    var Tree = Ext.tree;
    var tree;
</script>
 
Q1) What can be the possible issues here?
Q2) What can be done to fix the issue?
 
NOTE:
Both these orgs have the same managed package installed.
 
Awaiting a quick response.
 
Thanks and Regards,
Sudhanshu

Hi Sudhanshu,

If issue is with package provider you would need to reach out to them, let me know what is the package which you have installed.

Thanks,
