I've got a problem.
i want to use a AbstractWizardFormController for a FileUpload. in the first page i want, that the User select the upload-file with:
<form:form method="post" name="fileUploadController" enctype="multipart/form-data" commandName="file" id="form">
Please select a file: <br>
<input type="file" name="file"/>
<br><br>
<!-- <input type="submit"/> -->
<fieldset class="evenLast">
<p class="submit"><input type="submit" alignment="center" name="_target1" value="Up to Step 2" /></p>
</fieldset>
</form:form>
then on the Next Page, the User have to fill in some different other fields like "title" or "description".
<form:form method="post" name="fileUploadController" commandName="file" id="form">
Title:<br>
<spring:bind path="file.title">
<!-- <input type="text" name="title" value="<c:out value="${status.value}"/>"/> -->
<input type="text" name="title" />
<font color="red"><c:out value="${status.errorMessage}"/> </font>
</spring:bind>
<br><br>
Description:<br>
<spring:bind path="file.description">
<textarea rows="15" cols="40" name="description" ></textarea><br>
<font color="red"><c:out value="${status.errorMessage}"/> </font>
</spring:bind>
<br><br>
<fieldset class="evenLast">
<p class="submit"><input type="submit" alignment="center" name="_target2" value="Up to Step 3" /></p>
</fieldset>
</form:form>
in the end the User have to accept all this stuff
<form:form method="post" action="upload1.htm" name="fileUploadController" commandName="file" id="form">
...
<input type="submit" align="middle" name="_finish" value="Execute Order" />
</form:form>
but when the User execute the Finish method
processFinish(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception
it shows this ErrorMessage:
java.lang.IllegalStateException: File has already been moved - cannot be transferred again

this line contains this(media is my formbackingobject):
file.transferTo(new File(media.getPath()));
i know the problem is that the file has already been moved in the filesystem as is not available anymore for another transfer(java.lang.IllegalStateException)
when i set the Page, in which the user select the file, at the end it works. but i want that the User set the Upload file in the beginnen.
if somebody can solve this problem, i would be very very happy.
thank you very much in advance.
