I am trying to upload a file and I used the example here:
http://www.smartclient.com/smartgwte...se/#upload_sql
but I have issues.

My upload form is the following:

Code:

final DynamicForm editDokumenteForm =  new DynamicForm();
editDokumenteForm.setDataSource( DataSource.get( "dokumente" ) );
FileItem fileItem = new FileItem("f_datei", "Document"); 
editDokumenteForm.setFields( fileItem );

IButton editDokumenteOkButton = new IButton( "save" );
editDokumenteOkButton.addClickHandler(new ClickHandler() {
   public void onClick(ClickEvent event) {
      dokumenteEditForm.saveData();
   }
}

My Datasource:

Code:

<DataSource
    ID="dokumente"
	serverType="sql"
	tableName="t_dokumente"
>
    <fields>
    	<field name="f_id" type="sequence" primaryKey="true" />
	<field name="f_datei" type="imageFile" />

    </fields>
</DataSource>

I am using MSSQL. On my table definition I have:
f_id, primary key, with autoincrement.
f_datei, varbinary(max) null,
f_datei_date_created date null,
f_datei_filename varchar null,
f_datei_filesize int null.

When I click on the "save" Button, I get this exception:

Code:

So it seems the file is not being sent.

My RPC Request/Reply on the developer console:

Code:

RPC Request:

{
    "actionURL":"http://127.0.0.1:8888/zedes2/sc/IDACall", 
    "showPrompt":true, 
    "prompt":"Saving form...", 
    "transport":"xmlHttpRequest", 
    "promptStyle":"cursor", 
    "bypassCache":true, 
    "data":{
        "values":{
            "f_datei":"mozodojo-original-image.jpg", 
            "f_schueler_id":2
        }, 
        "operationConfig":{
            "dataSource":"dokumente", 
            "repo":null, 
            "operationType":"add"
        }, 
        "componentId":"isc_DynamicForm_2", 
        "appID":"builtinApplication", 
        "operation":"dokumente_add", 
        "oldValues":{
        }, 
        "streamResults":null, 
        "exportToFilesystem":null, 
        "exportToClient":null
    }
}

RPC Response:
[
    {
        data:"Wert f�r Parameternummer \"1\" wurde nicht festgelegt.", 
        invalidateCache:false, 
        isDSResponse:true, 
        queueStatus:-1, 
        status:-1
    }
]

DSRequest:
{
    "dataSource":"dokumente", 
    "operationType":"add", 
    "componentId":"isc_DynamicForm_2", 
    "data":{
        "f_datei":"mozodojo-original-image.jpg", 
        "f_schueler_id":2
    }, 
    "callback":{
        "target":[DynamicForm ID:isc_DynamicForm_2], 
        "methodName":"saveEditorReply"
    }, 
    "showPrompt":true, 
    "prompt":"Saving form...", 
    "oldValues":{
    }, 
    "clientContext":{
    }, 
    "requestId":"dokumente$62716"
}

So only the filename is being sent, not the filesize, lastmodified, and the binary data if I read this correctly.

So what's going wrong?

I use SmartGWT EE 3.0p and Firefox 13.0.1.
Thank you!

You are correct that the file is not being sent to the server - the Content-Type should be "multipart/form-data" when a file is being uploaded.

However the code you've shown won't reproduce the problem - you could create a problem like this if you had setCanSubmit(false), had tried to setEncoding(), etc. Try isolating the problem.
