Re: Can @Inject annotation be used instead of @SpringBean to inject Spring beans?

[Martin Grigorov]

Hi,

I use @SpringBean in my applications.
The only reason one to switch to @Inject is if your application may use
Guice in the future. Using @Inject will make it easier to migrate.

Can @Inject annotation be used instead of @SpringBean to inject Spring beans?

[James Selvakumar]

Hi all,

I've always used @SpringBean annotation to inject Spring beans in my Wicket
components.
We found that we could also use the standard @Inject annotation in Wicket
components.
Is it advisable to use @Inject instead of @SpringBean?
Or should we continue to use @SpringBean?

Thanks & regards

Sorry - my mistake. It exists in the source-code, only.
btw. some images cannot be embedded. There are errors like:

asciidoctor: WARNING: could not embed image:
/tmp/wicket/wicket-user-guide/src/main/asciidoc/img/inmethod-grid2.png;
PNG uses unsupported interlace method

NPE in constructor of AbstractWebSocketProcessor

[Maxim Solodovnik]

Hello All,

I'm observing weird behavior:
I'm displaying wicket page in iframe
For some unknown reason I'm getting NPE in [1] if page is being
reloaded both F5 and Shift+F5
Every second time I got NPE

The method is being called from [2], every second time
(HttpSession) userProperties.get("session") == NULL

maybe you know what can be done here?

Oh, I checked it twice, now. You are right Martin there seems something 
wrong with the complete build.


I compared master with wicket-7.x and the only thing which changes is 
the artifactId.


What I also noticed it that the 7.x folder is not created anymore at my 
local build. Can you confirm this? (even with profile guide)

Hi,

this seems an issue of the migration to adoc. It seems that the changes 
of master have been cherry picked to wicket-7.x.


We have to change the adoc in the wicket-7.x branch. The patch 
guide/single.pdf doesn't exist anymore, because of adoc.


There is only a single.html and a single.pdf in the main path.

kind regards

Tobias
