    Hello,

    I'm trying to get a chart in a portlet environment using Cewolf and WebSphere Portal 5.1 and 6.
    I'm getting an exception when cewolf tries to store the chart and I never get the image in the portlet. This happen using any storage (I tried with ClusterableSessionStorage, LongTermSessionStorage and TransientSessionStorage).

    The stacktrace is always something like this:

    Caused by: java.lang.NullPointerException
        at de.laures.cewolf.storage.AbstractSessionStorage.contains(AbstractSessionStorage.java:75)
        at de.laures.cewolf.storage.AbstractSessionStorage.storeChartImage(AbstractSessionStorage.java:53)
        at de.laures.cewolf.taglib.tags.ChartImgTag.doStartTag(ChartImgTag.java:79)
    ...
    ...
    ...

    I think that is a problem with cewolf running in the portlet environment.
    Any help to solve this problem?

    Regards,
    Pablo.

      Hello Pablo,

      Was you successful with the problem?
      I try the framework with portlet jsr168 and have the same trouble.

      Many thanks!

      Best Regards,
