Re: Problem with in Seam 1.2.1GA and Trinidad 1.0.1

Any time you have a ClassCastException with two classes
that should be just fine, check your classpath - thoroughly.
Look for a duplicate copy of trinidad.

Hi, Adam ...

Thanks for your answer. About the 2 possibilities, I see the source of this
projects (MyFaces / Trinidad) and my project, and I see this ... In the
source class "UploadedFiles" I see this:

        static public class FixFilename implements UploadedFile,
Serializable
        { ... }

and its implements is : import
org.apache.myfaces.trinidad.model.UploadedFile . And in my
source code, in my class "GestionPlantilla" I see this:

    public void fileUploaded(ValueChangeEvent event)
    {
        UploadedFile archivo = (UploadedFile) event.getNewValue();
        if (archivo != null) {
            archivoPlantilla = archivo;
        }
    }

ant its implements is import
org.apache.myfaces.trinidad.model.UploadedFile. Are the
same Interfaces. And I be carefull, and I use the same version of Trinidad,
1.0.1 and MyFaces 1.1.5. I only put this:

    <context-param>
        <!-- Maximum memory per request (in bytes) -->

<param-name>org.apache.myfaces.trinidad.UPLOAD_MAX_MEMORY</param-name>
        <!-- Use 2000K -->
        <param-value>2048000</param-value>
    </context-param>
    <context-param>
        <!-- Maximum disk space per request (in bytes) -->
        <param-name>

org.apache.myfaces.trinidad.UPLOAD_MAX_DISK_SPACE
        </param-name>
        <!-- Use 20,000K -->
        <param-value>20480000</param-value>
    </context-param>

but, same ... doesn't work. Thanks for your help.
