Exception in Workbench Tree

I've checked out the latest from CVS and I'm getting an exception in
the Workbench Tree example code.  I've run this under both Jetty and
Tomcat and the same exception appears.  Here is the (truncated) report
from Tapestry:

org.apache.tapestry.ApplicationRuntimeException
component: org.apache.tapestry.workbench.tree.examples.FileSystemTreeTable@a56214[FileSystemTableTree]
location: context:/WEB-INF/FileSystemTableTree.page, line 8

java.lang.NullPointerException
Stack Trace:

    * org.apache.tapestry.contrib.table.components.TableView.getTableColumnModel(TableView.java:341)
    * org.apache.tapestry.contrib.table.components.TableView.generateTableModel(TableView.java:250)
    * org.apache.tapestry.contrib.table.components.TableViewSessionStateManager.recreateTableModel(TableViewSessionStateManager.java:107)
    * org.apache.tapestry.contrib.table.components.TableView.getTableModel(TableView.java:225)
    * org.apache.tapestry.contrib.table.components.TableView.validateValues(TableView.java:454)
    * org.apache.tapestry.contrib.table.components.TableView.renderComponent(TableView.java:483)
* org.apache.tapestry.AbstractComponent.render(AbstractComponent.java:898)

I put a few println statements in TableView.java, and the line:

        Object objColumns = getColumns();

in the getTableColumnModel() method appears to be the culprit.  The
objColumns value is null.  I tried poking around a bit to ensure that
the parameters were being bound correctly, but I don't have the
time/expertise to do this at the moment (sorry).

Let me know if I need to submit a bug report (and where I need to
do this!).

Thanks.

I nuked my cvs checkout of Tapestry, re-checked out, and it now
works fine.  Must have caught something in transition.

Hi,

Strange... it is working fine for me at the moment... Could you try to
synchronize once again and try then? May be some changes did not make it in
earlier...

In any case, thanks for sending it.
