One of the cool features added in PeopleTools 8.4 was drag and drop in tree manager. Yesterday, as we were installing Report Explorer at another customer, they mentioned that recently drag and drop stopped working in their environment. Interestingly, they had been dealing with that issue for quite some time although the solution was relatively simple.

Drag and Drop in Tree Manager... What's that?
Drag and drop allows you to move tree nodes around within a tree without requiring you to cut and paste them. This makes the product much more usable, when you are resequencing nodes or moving subtrees from one location to another. For companies that perform reorganizations on a regular basis, this feature is a life saver.



Okay, so why did it break all of a sudden?
Good question. The drag and drop features in Tree Manager are enabled through some javascript embedded in the Tree Manager page. In almost all the circumstances where drag and drop stops working, it has to do with the security settings in Internet Explorer.

Mike Friedman put together a very good posting on the IEBlog that explains how Internet Explorer applies and manages security related to JavaScript and other embedded objects that could be used to perform malicious activities on a machine.

Great... How do I fix it?
Fortunately, the fix is relatively simple. You merely need to make your PeopleSoft URI a trusted site in Internet explorer. In the default IE configuration, JavaScript will execute on a trusted site.

Here's how you do it. First, you go into Internet Explorer and use the Tools menu and select Internet Options.



You will then be displayed the Internet Options dialog. Click on the Security tab to modify the security settings.



Finally, click on the Trusted Sites button and enter your PeopleSoft site into it. You can use wildcards in the URL, if you like.



Drag and Drop should start working if you put in a valid address.
