    gjt3,

    The screenshot is missing from your report. Please reattach it.

    Can you please give us some more details?

    1. Have you installed any third party plugins or make any changes to the MyEclipse IDE which might have broken the install ?

    2. Please let us know which project you are (java/web/ejb/ear etc) creating. Does the error prevent you from creating the project?

    3. Can you please check if the issue persists in a new workspace? If yes, then please share with us the full log file from workspace dir/.metadata/.log for further investigation.

    Apologies for inconvenience caused.

    1. Have you installed any third party plugins or make any changes to the MyEclipse IDE which might have broken the install ? No additional plugin activity

    2. Please let us know which project you are (java/web/ejb/ear etc) creating. Does the error prevent you from creating the project? Have successfully create ear / web projects. with any server activity, the null exception window pops up.

    3. Can you please check if the issue persists in a new workspace? If yes, then please share with us the full log file from workspace dir/.metadata/.log for further investigation. Persists in new workspace

    gjt3,

    Thanks for the information. With SWT errors, it is often a problem with internal UI model corruption. Could you try opening a new window (Window->New Window) then close the old window. Does that help? If not, can you think of anything that changed in your system before you started to see this problem?

    I see where you create “New Window:
    1. What exactly does this do for me?
    2. Steps to close current window without affecting new one

    gjt3,

    The new window will have an internal UI model built from scratch. Otherwise it is the same as your main window that opens when MyEclipse starts. You can close the old window by using any method for closing windows of any application, for example, by clicking the X at the top right of the window. MyEclipse, itself, will not shut down unless the window being closed is the only window open on the workbench.

    Please let us know how you get on.

    gjt3,

    Sorry that the issue persists. I am afraid the attachments are missing from your response.
    Please change the extension of the .log file to .txt and attach it.
