Resolves #926

I would also

• use *.css from webjars for this base theme wicket-jquery-ui-parent/wicket-jquery-ui-themes/theme-base/src/main/java/com/googlecode/wicket/jquery/ui/theme/Initializer.java
• WicketWebjars.install(this); should be added to wicket-jquery-ui-parent/wicket-jquery-ui-samples/src/main/java/com/googlecode/wicket/jquery/ui/samples/SampleApplication.java, otherwise examples will not work ....

Hello @martin-g,

It seems this PR breaks samples

Webjars are being used from Initializer from now on

so we got

Caused by: java.lang.IllegalStateException: you have to call WicketWebjars.install() before you can use an IWebjarsResourceReference or any other component.

due to WicketWebjars.install(this); is being called in the init() i.e. too late :(

What can be done here?

[martin-g]

As error message suggests we need to add 'WicketWebjars.install()' to the respective WebApplication#init()

[martin-g]

Oh, now I see the text after the stacktrace.
I think it should be OK to call it in an initializer too.

[solomax]

Works as expected!

Thanks a million @martin-g :)

@solomax so how did you solve this?

I think this change needs to be made in the initializer of all of the themes separately.

I think this change needs to be made in the initializer of all of the themes separately.

I also thought so

But I believe right now it's not necessary due to the fact the only theme uses webjar so far :)

I have created a PR #934 to resolve this
