  • 1.  Gantt View is completely blank despite project having many tasks

    Posted Feb 20, 2015 08:12 AM

    Got a weird issue that hopefully someone can solve.

     

    We have a project that has many tasks which appear in the regular Task List but when you open the Gantt Editor, no tasks display.  We don't get an error, just a blank Gantt page.

     

    This is the first time I've seen something like this.

     

    Any ideas?

    So no tasks ? and not just no bars?

    Which CA PPM version?

    All users and any workstation and any browser?

    Yes no tasks, no bars.

     

    This is on 13.3 and just for this one project.

    Three possibilities that I'm aware of:

     

    1. Filter:
      1. open up the filter in the Gantt view and make sure there are no default settings that may be excluding your tasks.
      2. Sorry if this is obvious and you've done this already - don't want to assume so and miss an easy fix
    2. Refresh:
      1. hitting the 'refresh' link in the Gantt window may bring up the tasks
      2. we are on 13.1 - haven't seen the issue in months but it may be due to our move from HTTP to HTTPS - though not specifically addressing the blank Gantt chart, it may have affected our caching for the better
    3. Refresh doesn't work - Corrupted WBS Sequence
      1. In this case, the WBS sequence was corrupted - hitting refresh did nothing
      2. Our solution was to export the project to MSP, then save it back to Clarity.  This action refreshed the WBS sequence, allowing the tasks to be displayed in the Clarity Gantt view.

    Hope you find something helpful, here.

    Does it display any better in either of the external schedulers (OWB and MS Project)?

     

    When a project does not display in the project list that is typically caused by -99 value in the last_update_by field.

    If that were the case for the WBS in this case it would not display in the Clarity GUI either.

    Another hickup I've seen recently was a non-ascii chracter in the task name, but that again threw an error in the GUI and did not display the task list either.

    Round tripping the project in a scheduler (MSP or OWB) usually fixes this.

    YES! That worked.  Thanks!

    Same as Item 3 in my earlier post.
