Resource Usage

My users have started to notice that the resource usage histogram is blank sometime.

Here is what we did to duplicate the problem.

1.  Create a new project with new resources.

2.  Assign the new resources to activities with planned hour and duration.

3.  Schedule the project in the Web interface.

4.  Summarize the project.

  

Team Usage shows correctly, but under the Resource/Analysis of role or resource the histogram is empty.  The spreadsheet displays the correct information.

We are using P6 v8.2.1

The workstation has java 1.6.0_27 and the java cache has been cleared.  By the way we see the same results on other workstations.
