Some ref to utilelement table and creation of shared project

As far my experience utilelements table get updated when the service is started.
It may also get updated when the customisation is imported into the application.

The code shown below how to delete a shared project

treenode c1,c2;
;

c1 = systemnode::getsharedproject();
c2 = c1.aotfindchild("project1");

c2.aotdelete();
c2.aotrefresh();
c2.aotsave();
