Description

Since we decided to use Tiles 2 in our project, we had to upgrade from tomahawk 1.1.6 to the next available version (currently tomahawk 1.1.7 snapshot) to be able to use the JspTilesTwoViewHandler. However, with this upgrade, we now get the following exception on pages using the t:inputFileUpload tag:

To be more precise: the exception occurrs on pages containing a sortable table and the and at least one t:inputFileUpload (both in the same form). Whenever the table is sorted, the exception is thrown. Unfortunately, all other command links do not work for the next click!

The $1 at the end of UploadedFileDefaultMemoryImpl$1 indicates that there is an inner class which does not implement the Serializable interface.
