Martijn Dashorst commented on WICKET-5702:
------------------------------------------

We use the following class to wrap around StringResourceModel and I think it 
has a much better API:

{code:java}
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import org.apache.wicket.Component;
import org.apache.wicket.model.IModel;
import org.apache.wicket.model.StringResourceModel;

public class I18N implements Serializable
{
        private static final long serialVersionUID = 1L;

        private String key;

        private Component component;

        private IModel< ? > model;

        private String defaultValue;

        private List<Serializable> parameters = new ArrayList<>();

        private I18N(String key)
        {
                this.key = key;
        }

        public static I18N of(String key)
        {
                return new I18N(key);
        }

        public I18N from(Component component)
        {
                this.component = component;
                return this;
        }

        public I18N withModel(IModel< ? > model)
        {
                this.model = model;
                return this;
        }

        public I18N with(Serializable parameter)
        {
                parameters.add(parameter);
                return this;
        }

        public I18N withDefault(String defaultValue)
        {
                this.defaultValue = defaultValue;
                return this;
        }

        public IModel<String> toStringModel()
        {
                return new StringResourceModel(key, component, model, 
defaultValue, parameters.toArray());
        }

        @Override
        public String toString()
        {
                return toStringModel().getObject();
        }
}
{code}

> When using StringResourceModel with substitution parameters the placeholders 
> in the resulting string are not replaced.
> We are migrating from 6.14 to 7.0.0-M3 and in 6.14 (and 6.17) it was working 
> es expected. I attached a quickstart-project to show how we use 
> StringResourceModel in our project and how to reproduce this issue.
