Re: CompoundPropertyModel works different in wicket-7.x and master

[Sven Meier]

Hi Tobias,

I'm not sure: CompoundPropertyModel#bind() has a generic type parameter, 
perhaps this is treated differently in Java 7 vs. 8.

Hi Sven,

so the behavior of wicket-7.x is right then? Because getObect receives the 
actual nested model and not src as model object?

Then we have an error in master.

kind regards

Tobias

Hi Tobios,

new ExternalImage("compoundImage",compoundPropertyModel.bind("url")));

this invokes the constructor with the Serializable argument, effectively 
wrapping the propertyModel inside a normal model.

Have fun

Hi guys,

Martin mentioned to me that my last integration breaks the build of Wicket-7.x.

As I saw master compiled fine. After a short research we found out that the 
CompoundPropertyModel works slightly different.

Output in wicket-7.x:

<img wicket:id="compoundImage" 
src="Model:classname=[org.apache.wicket.model.PropertyModel]:nestedModel=[Model:classname=[org.apache.wicket.model.CompoundPropertyModel]:nestedModel=[org.apache.wicket.markup.html.image.ExternalImageTestPage$ImageSrc@7cdbc5d3]]:expression=[url]"/>

Output in master:

<img wicket:id="compoundImage" src="http://www.google.de/test.jpg"/>

Invokation:

         ImageSrc imageSrc = new ImageSrc();
         imageSrc.setUrl("http://www.google.de/test.jpg";);
         CompoundPropertyModel<ImageSrc> compoundPropertyModel = new 
CompoundPropertyModel<ImageSrc>(imageSrc);
         add(new 
ExternalImage("compoundImage",compoundPropertyModel.bind("url")));

Code to receive the model object. String.valueOf(model.getObject());

I don't know what changed, but maybe you know.

kind regards

Tobias
