Re: upload file content to textarea
You could ajax update the textarea after upload, with the content that you want? If you do not want to set the model object then you will have to fake raw input (reflection). ** Martin 2009/9/16 Sam Zilverberg samzilverb...@gmail.com: In one of my wizard's steps I have a upload form and a textarea. The textarea is used to enter serial numbers(seperated by newline) and is connected to a object property of type SetString using a propertymodel. I've written a custom converter to turn the entered input to a SetString and from a SetString back to simple string. When pressing the wizard's next the input is validated and if valid the backing model will have SetString of serials. I want the upload form to be used to upload a file containing serial numbers. I would like that the content of the uploaded file will be placed into the textarea, so that when Next is pressed again it is validated. Is this possible? Can I put the file's content into the text area by pressing upload without ruining the property model the textarea uses? - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

sounds good, but how do I do this? :) On Wed, Sep 16, 2009 at 9:45 PM, Martin Makundi martin.maku...@koodaripalvelut.com wrote: You could ajax update the textarea after upload, with the content that you want?

Re: upload file content to textarea
1. You know how to upload file? http://www.wicket-library.com/wicket-examples/upload/single - or ajax upload http://blog.demay-fr.net/index.php/2007/12/07/93-simulate-ajax-file-upload-with-wicket 2. Just put the file contents into textarea with jafa reflection. 3. AJax update the textarea: http://www.wicket-library.com/wicket-examples/ajax/clock.2 - This is timed update..but similarly just add the textarea into ajax target. ** Martin 2009/9/16 Sam Zilverberg samzilverb...@gmail.com: sounds good, but how do I do this? :) On Wed, Sep 16, 2009 at 9:45 PM, Martin Makundi martin.maku...@koodaripalvelut.com wrote: You could ajax update the textarea after upload, with the content that you want?

Re: upload file content to textarea
thanks a lot for the help and the links! I checked them all out, the second one (upload panel) was too complicated for me atm. Maybe I'l come back to it when I'l have more experience with wicket. I liked the timed ajax behaviour example, but couldn't figure out exactly how it works so i could use it in my project. ??how does the behaviour know how to update the clock?? I currently solved this problem by filtering the input from the uploaded file and creating a correct object model (SetString) out of it, then setting the modelObject of the textarea to be this filtered one. I also didn't understand what you meant by simply using reflection to put the content of the file into the textarea, did you mean simply using setModelObject( (SetString) uploadedContent) ? thanks again for all the help so far On Wed, Sep 16, 2009 at 11:32 PM, Martin Makundi martin.maku...@koodaripalvelut.com wrote: 1.

Re: upload file content to textarea
Hi!
I currently solved this problem by filtering the input from the uploaded
file and creating a correct object model (SetString) out of it,
then setting the modelObject of the textarea to be this filtered one.
Good, so you got the upload part working.
By reflection I mean that instead of setting model object you could do
this, if necessary:
public static T extends FormComponent? void fakeRawInput(T
formComponent, T existingComponent) {
try {
String rawInput = (String) rawInputField.get(existingComponent);
fakeRawInput(formComponent, rawInput);
} catch (Exception e) {
Utils.errorLog(MarkupUtils.class, Fatal Error: Form field
access failed., e);
}
}
In this way your modelObject state does not change as compared to:
simply using setModelObject( (SetString) uploadedContent) ?
But if you can change the model that's definitely cleaner.

Ah.. forgot that crucial part, the reflection:

formComponent, String value) {
try {
rawInputField.set(formComponent, value);
} catch (Exception e) {
Utils.errorLog(MarkupUtils.class, Fatal Error: Form field

Re: upload file content to textarea
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=uploadFile/label
input wicket:id=fileInput id=upload type=file /
button wicket:id=uploadButton span
wicket:id=uploadLabelupload/span/button
/fieldset
/form
/td
td
wicket:message key=serials.textareaInfoinfo
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();
}
}
}
}

Re: upload file content to textarea
No.. the field name is rawInput:
rawInputField = FormComponent.class.getDeclaredField(rawInput);
