Question: I have a div into my html project gwt `<div id="myproject"></div>` how can add this into a specific vertical panel?

Answer: 
I'm not really sure what you are exactly trying to achieve but the way I understand it, you could do the following.

* Add a String parameter to your root job. Affect it the BUILD\_USER variable value. ie:`${BUILD_USER}`
* Then just pass the Current Build Parameters in the 'Post-build Actions -> Trigger parameterized build on other projects' section.

The subsequent job will be able to read the variable.
For the most part it seems this question has been answered but I want to add something useful for those with multiple copies of Jenkins, and other products on their machine:

I have a few Jenkins Servers linked to an SVN doing something similar to what you are trying to do. I have script save the User Name of person who initialized the commit when a post commit hook is triggered to Main Jenkins. That way no matter which Job, Jenkins, or other server you are using you can have access to that info.
