Re: ResourceReference that contains relative paths

Hi,

The easiest solution is to move BootstrapCssResourceReference.java one
level up and change the relative path to: css/bootstrap.css

The WicketStuff team

[ANNOUNCE] Apache Wicket 8.0.0-M6 released

[Andrea Del Bene]

The Apache Wicket PMC is proud to announce Apache Wicket 8.0.0-M6!

Apache Wicket is an open source Java component oriented web application
framework that powers thousands of web applications and web sites for
governments, stores, universities, cities, banks, email providers, and
more. You can find more about Apache Wicket at https://wicket.apache.org

This release marks another minor release of Wicket 8. We
use semantic versioning for the development of Wicket, and as such no
API breaks are present breaks are present in this release compared to
8.0.0.

New and noteworthy

--
With this version Wicket removed its internal JSON implementation
(based on project JSON-java: https://github.com/stleary/JSON-java)
replacing it with external project Open JSON
(https://github.com/openjson/openjson).
This was necessary as JSON-java's license is no longer compatible with
Apache License 2.0.


Using this release
--

With Apache Maven update your dependency to (and don't forget to
update any other dependencies on Wicket projects to the same version):


org.apache.wicket
wicket-core
8.0.0-M6


Or download and build the distribution yourself, or use our
convenience binary package

 * Source: http://www.apache.org/dyn/closer.cgi/wicket/8.0.0-M6
 * Binary: http://www.apache.org/dyn/closer.cgi/wicket/8.0.0-M6/binaries

Upgrading from earlier versions
---

If you upgrade from 8.y.z this release is a drop in replacement. If
you come from a version prior to 8.0.0, please read our Wicket 8
migration guide found at

 * http://s.apache.org/wicket8migrate

Have fun!

Re: Wicket page expired if push button to open new page

[Maxim Solodovnik]

In case Ajax is available you can start with button disabled by default
Then add AbstractDefaultAjaxBehavior to the page and trigger it on dom ready:

@Override
public void renderHead(IHeaderResponse response) {
 
response.render(OnDomReadyHeaderItem.forScript(myBehavior.getCallbackScript()));
}

and enable your buttons in myBehavior response

Hi,

See PageExpiredException javadoc.
The exception is not thrown only when the session is expired.
Most probably the page has not be saved at all.

Re: Access to Dynamically Generated AjaxEditableLabel Value

Hi,

You have to update the models, so you are doing it right!
Please create a simple demo application and share it with us (e.g. at
GitHub, BitBucket) and we will try to see where is the problem.

Hi Martin,
Thank you for your answer.
I changed the the Model of the AEL but still can not retrieve the values
which are entered in them. Could you please let me know how can I retrieve
these values for each row of table?


Thanks in advance

Re: Access to Dynamically Generated AjaxEditableLabel Value

[Martin Grigorov]

Hi,

You are using "cellItem.add(new AjaxEditableLabel(componentId)"
i.e. the AEL has no its own model but uses IComponentInheritedModel from
its parents.
Try by using a model for AEL: cellItem.add(new
AjaxEditableLabel(componentId,
Model.of(0))
