ClassCastException after upgrade to 0.9.3.v7

[fracz]

I have an instance of FilterTable in which I want to support drag&drop feature of rows. I do it by sample code:

table.setDragMode(TableDragMode.ROW);
table.setDropHandler( /* my drop handler */ );

Until 0.9.2.v7 everything worked fine. After upgrade to 0.9.3.v7 and drag&drop some row, the exception is being thrown:

java.lang.ClassCastException: org.tepi.filtertable.FilterTable cannot be cast to com.vaadin.ui.Table

After downgrade to 0.9.2.v7 it works again with no exception. Vaadin 7.1.9.

Thanks for noticing! This will be fixed in the upcoming 0.9.4.v7 version.

Is it planned to update vaadin6 branch with this fix?
