I try to add simple java project to Deployment Assembly and it disappear

Question

Hi stackoverflower,
I use eclipse Helios and this is my problem.

I have main project name main. It is Dynamic Web Project.
I have util project name util. It is Simple Java Project.

I open Deployment Assembly from main project.
I click Add -> Project -> choose util project-> Finish
In my screen show new project in table

Source : util | Deploy Path : /WEB-INF/lib/util.jar

Anything look good, I click OK.
But when I go to Deployment Assembly again util project disappear.
And sure that when I deploy, util project doesn't become jar file library.

Thanks for all suggestion.

To echo my comments above, I took notice of bug 318068 "Aggregate Deployment Assembly fixes for Helios SR1", which includes a lot a bug fixes regarding that feature.

The OP diewland reports:

It works! I update eclipse and anything is ok.

So Eclipse3.6.1 is recommended for "Deployment Assembly" operations.
