I tried to pull up the "boolean defaultVisible" parameter to the ParentPanel
, but still the same error ....
public abstract class AbstractPullDownPanel extends Panel
{
private final WebMarkupContainer content;
public AbstractPullDownPanel(String id , String title , final boolean
defaultVisible)
{
super(id);
Label titleLabel = new Label("title" , title);
content = new WebMarkupContainer("content")
{
@Override
public boolean isTransparentResolver()
{
return true;
}
};
content.setOutputMarkupPlaceholderTag(true);
content.setVisible(defaultVisible);
add(content);
final Label collapseExpandText = new Label("collapseExpandText");
collapseExpandText.setOutputMarkupPlaceholderTag(true);
if (content.isVisible())
collapseExpandText.setModel(new StringResourceModel("collapse" , this
, null));
else
collapseExpandText.setModel(new StringResourceModel("expand" , this ,
null));
Link collapseExpandLink = new AjaxFallbackLink("collapseExpandLink")
{
@Override
public void onClick(AjaxRequestTarget target)
{
if (content.isVisible())
{
target.addComponent(content.setVisible(false));
target.addComponent(collapseExpandText.setModel(new
StringResourceModel("expand" , this , null)));
//call template method
invisible();
}
else
{
target.addComponent(content.setVisible(true));
target.addComponent(collapseExpandText.setModel(new
StringResourceModel("collapse" , this , null)));
//call template method
visible();
}
}
};
add(collapseExpandLink);
collapseExpandLink.add(collapseExpandText);
collapseExpandLink.add(titleLabel);
}
