Re: Regarding "WARN - (WebPageRenderer.java:162)" v1.5.7

[yesotaso]

Just tested with 6.0:

create new project: "mvn archetype:generate
-DarchetypeGroupId=org.apache.wicket
-DarchetypeArtifactId=wicket-archetype-quickstart -DarchetypeVersion=6.0.0
-DgroupId=com.mycompany -DartifactId=myproject
-DarchetypeRepository=https://repository.apache.org/
-DinteractiveMode=false"

open WicketApplication.java and add following lines to init() method:
*setRootRequestMapper(new CryptoMapper(getRootRequestMapper(), this));
mountPage("/home", HomePage.class);*

read following from console:
*WARN  - WebPageRenderer- The Buffered response should be
handled by BufferedResponseRequestHandler*

Is it bad practice to have both MountedMapper and CryptoMapper?

Please  disregard above comment... I was trying to reproduce mentioned

Will do, at the moment trying to isolate the incident.

Regarding "WARN - (WebPageRenderer.java:162)" v1.5.7

[yesotaso]

Sorry for non-informative title. The whole warning is:
WARN  - (WebPageRenderer.java:162) - The Buffered response should be handled
by BufferedResponseRequestHandler
I know in various places it is said to be harmless and I dont know if other
people seeing this warning for the same reason as me...
Mine's cuase is as it seems "If I access a page via either a link or typing
adress to a mounted page this warning pops up. In addition I use
*org.apache.wicket.request.mapper.CryptoMapper* in my authorization strategy
class. Somehow root request mapper pass response twice and at second time
since the stored response is still in the buffer it complains."

Question is : Is there any solution to avoid this warning?

PS: if I remove authorization strategy this warning does not show up.

Re: java pojo/Bean to generate html (textfield, dropdown,radio buttons)

[yesotaso]

While I absolutely agree with Thomas, I'd suggest using a text generator
template like FTL, Ruby or even String#format will do as well :) Below is a
FTL piece.

Re: how to connect elements - label and input (checkbox)

[yesotaso]

I am not exactly sure if it is what you want but I used a decoretor for
labeling task.
public class SimpleDecorator extends Behavior implements
IAjaxRegionMarkupIdProvider{
@Override
public String getAjaxRegionMarkupId(Component component){
// This method is overriden from IAjaxRegionMarkupIdProvider see its
@JavaDoc for details
return component.getMarkupId() + "_fd";
}

@Override
public void bind(Component component) {
component.setOutputMarkupId(true);
}

@Override
public void beforeRender(Component component) {
FormComponent fc = (FormComponent) component;
Response r = component.getResponse();
String label = (fc.getLabel() != null) ? 
fc.getLabel().getObject()  : null;

if(fc.getParent() instanceof FormComponent) {
label = null;
}

if (label != null) {
r.write("");
r.write(Strings.escapeMarkup(label));
if (fc.isRequired()) {
// You can put a "*" or something else if field is required
}
r.write("");
}
super.beforeRender(component);
}
@Override
public void afterRender(Component component) {
Response r = component.getResponse();
r.write("
