how does your LDM load its model object?

Show us some code or better create a quickstart so someone can take a 
look at it.

However, I have also a drop down inside the form, but when changing the
value, the LoadableDetacheableModel does not get updated with the new
value.

Or if using getModelObject(), all values are null, because, the backing
model of the form is null.

Could you please advise?

Thank you

Re: Change language

[Martin Grigorov]

Hi,

I usually use setResponsePage(Class) for such use cases.
But I also agree that the two failing components should be improved to and
support dynamic models!

Form with backing loadabledetachable model

[ganea iulia]

Hello,
I have a list of items in a Refreshing View.
When I click on a link inside the Refreshing View, a form in the same page
should get populated with the values from the line.

I have managed to do this, by having inside the Form a
LoadableDetacheableModel and then use this model as backing model for the
components in the form.

However, I have also a drop down inside the form, but when changing the
value, the LoadableDetacheableModel does not get updated with the new
value.

Or if using getModelObject(), all values are null, because, the backing
model of the form is null.

Could you please advise?

Thank you

Re: Reading Image from absolute path

[Tobias Soloschenko]

Hi,

if you mean absolute file system path

https://ci.apache.org/projects/wicket/apidocs/7.x/org/apache/wicket/resource/FileSystemResourceReference.html

If you mean path my URL:

https://ci.apache.org/projects/wicket/apidocs/7.x/org/apache/wicket/markup/html/image/ExternalImage.html

Examples are in the javadoc

kind regards

Tobias

Re: Reading Image from absolute path

I think this example

http://wicketinaction.com/2011/07/wicket-1-5-mounting-resources/

will do if you implement the getBytes method to read image from file system.

Reading Image from absolute path

[ganea iulia]

Hello,
Wicket 7.

I have been struggling to read an image from absolute path but with no luck.

I have a folder with some images inside catalina base directory from where
I need to display images in my web page.
However, this does not work.


Could you please guide me on how to do this?

Thank you.
