Subject [jira] Updated: (BEEHIVE-879) collapse/expand tree button does not work for two tree portlets on one page - fix netui-tree.js

Carlin Rogers updated BEEHIVE-879:
----------------------------------

    Attachment: j879-test-patch.txt

Rich, here's a patch that includes a test recorder test running in MockPortal.

To see the JavaScript errors (old behavior) you can run the test manually and
view problems in a JavaScript console. First build the coreWeb DRT web app
and deploy. Modify the coreWeb/resources/beehive/version1/javascript/netui-tree.js
file to back out the change that was committed with the earlier patch for this bug.
(I.E. remove the if statement around the "var netUI = new NetUI();" line at the top
of the file). Start the server and with a browser go to the page,
http://localhost:8080/coreWeb/mockportal/treetest/TreesMockPortal.jsp
Then expand the first tree. There will be JavaScript errors that 
"netUI.netUITree.trees[treeName] has no properties" in netui-tree.js
If the tree does expand, it is done only on the server side.

However, with the new fix now in netui-tree.js, you will not see the
error messages and the tree will expand on the client side.

> When two portlets with trees are included on one page, collapse/expand tree 
> button does not work.
> There is a script tag written referring to netui-tree.js for every tree written out on

> the page.  The netui-tree.js file defines the global netUI variable. The script is 
> getting included multiple times on a page, the netUI variable keeps getting 
> redefined.  The tree information is being stored in this variable, and then getting 
> wiped out the next time the file is included.
> In netui-tree.js we need to change 
> var netUI = new NetUI();
> to 
> if (!netUI) {
>     var netUI = new NetUI();
