I'd rather use some other method than mine, because with mine the validation
of input is done twice when uploading.
first on the uploaded file, and then another time on the textarea when
pressing the wizard's next button.
I tried replacing my "fixup" with this one but got a big fat
java.lang.NoSuchFieldException
on getDeclaredField( name) line in the code.
I got this a couple of times using different names such as
TextArea.class.getSimpleName() and "serials" (the wicket id for the
textarea).
Any ideas on what name I should be using?
heres some code and the markup for the wizard page with the upload
form/textarea :
<wicket:panel>
<table>
<tr>
<td>
<form wicket:id="simpleUpload">
<fieldset>
<label for="upload">File</label>
<input wicket:id="fileInput" id="upload" type="file" />
<button wicket:id="uploadButton" ><span
wicket:id="uploadLabel">upload</span></button>
</fieldset>
</form>
</td>
<td>
<wicket:message key="serials.textareaInfo">info
message</wicket:message> <br/>
<textarea wicket:id="serials"></textarea>
</td>
</tr>
</table>
i'm using <button wicket:id="uploadButton" > in the markup instead of <input
type="submit"> as per the example
because pressing the latter button causes the whole wizard page to validate,
including the text area which is usualy empty
in the case of file upload.
Button uploadButton = new Button("uploadButton") {
@Override
public void onSubmit() {
final FileUpload upload =
fileUploadField.getFileUpload();
if (upload != null) {
String uploadedContent = new
String(upload.getBytes());
try {
Field f =
FormComponent.class.getDeclaredField(TextArea.class.getSimpleName());
f.setAccessible(true);
f.set(textArea, uploadedContent);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
