How to create a file upload browser in spring roo?

[Harald Walker]

Furthermore, normally after saving a record roo redirects to a page that show the record just stored.
In case of the upload form roo return to the form (but the file has been uploaded).

You might be running into an exception which is not being displayed. That would explain why you go back to the form and don't see the correct results in the database. You could set a breakpoint in the BigController_Roo_Controller.aj create method to see what's happening.

BTW, if you only want to move the uploaded file to a different location you can use the transferTo method of CommonsMultipartFile.

I've tried to debug on the BigController_Roo_Controller.aj create method but everything seams to run well.

Here are the debug info:

Does anyone has been able to apply this to the <form:update>?

As soon as I add the enctype="multipart/form-data" to the form:update, as I did successfully to form:create, I get a persistence error:

org.hibernate.PersistentObjectException: detached entity passed to persist: valizatools.com.server.domain.Artist; nested exception is javax.persistence.PersistenceException: org.hibernate.PersistentObjectException: detached entity passed to persist: valizatools.com.server.domain.Artist

I can't wait!

[pccwodc]

I really don't know how to do it.

[adam37]

Maybe you should give a look to this video:
http://www.youtube.com/watch?v=0cZCgrskkaQ

I don't know if it could help you, but it could be a start.
Bye

[delgad9]

@adam37

Oh no, you got the buggy one...
I wished you would have used the latest version of my tutorial for your video. The one without the nasty exception.

Too bad
jD

[adam37]

:S...
Could you be more precise?
Where can I find the second version of your tutorial?
Thank you very much for the tutorial!!!

[delgad9]

(:S...)++

Tell you what... Put an attribution notice -given credit to the tutorial's author; which I truly believe is the correct way to proceed anyway- to the video and I let you access to 2nd version.

As a matter of fact, I have a business proposition for you since -with exception of the music- I think you did a great job creating a video of my tutorial.

We can join efforts for serving better the SR community; I have many-many of those tutorials -that you can turn into videos- which the SR community has shown great interest on them.

What you think?
