Hello everyone,
I insert 2 portlet in a user defined canvas. And i try to drag these portlets.
I see the log file, sometime I can catch nullpointexception as follows (I log the data paramHandler.getParameter("canvas") in MashboardServlet.java):

---------------------------------------------------------------------------------
paramHandler.getParameter::{"name": "test", "type": "user", "portletRefs": {"portletRef": [{"ref": "engadget", "row": 0, "col": 2}]}}
paramHandler.getParameter::{"name": "test", "type": "user", "portletRefs": {"portletRef": [{"ref": "engadget", "row": 0, "col": 2}]}}

Sometimes I have got another NullpointException:

Can someone tell me the reason?
Thanks a lot for your answer!!

Just a moment, I have got ArrayIndexOutOfBoundsException, after that, when i try to drag portlets, this exception appears always and the user's canvas cann't be saved.

---------------------------------------------------------------------------------

from the log of paramHandler.getParameter("canvas"), I have found, there is a portlet to disappear automatically.
It is strange. Have someone this problem?

[bhanley]

Can you post your mashconfig file for the user that is logged in when you hit these exceptions?

Thanks.

[kiki]

my mashconfig file is:






<body urlType="shared" url="portal.jsp?canvasName=Blank&canvasType=global" />







imgalt="Current Radar for Boston, MA">














imgalt="High Resolution Radar for Boston, MA">





imgalt="Forecast for Boston, MA">






imgalt="Blank Canvas Instructions" copies="0">
url="content/CanvasIntro.html" />







The exception appears when i in a user canvas, not a global canvas.

[bhanley]

What user are you logged in as? Are you logged in as "Administrator"? There are some issues if you try and create a user canvas as the protected "administrator" user that is added to the iServer on installation. Try creating a user on your system and logging in as them rather than Administrator.

[kiki]

I have tried to log in as another user, who's role in iserver includes administrator.
But this exception appears sometimes. When ArrayIndexOutOfBoundsException appears, then user's canvas cann't be saved, until i restart the iportal.
I search such a exception in intenet, for example: Re: ArrayIndexOutOfBoundsException on Serialization using JAXB 2.1, they run their application, sometimes also catch the same exception as in mashboard.
I think the problem is from jaxb, which version of jaxb and jdk in mashboard?
