So i got these 2 text boxes and I'm trying to concatenate them together and show the result in label. I found an example and did it like in the example but something is wrong. So maybe some one can see what I am doing wrong, because i have just started and don't understand how to do it properly. <pre><code>public class HomePage extends WebPage { private String fNumber="Big"; private String sNumber=" text!"; private String sResult=fNumber+sNumber; public HomePage() { PropertyModel<String> firstNumber = new PropertyModel<String>(this, "fNumber"); PropertyModel<String> secondNumber = new PropertyModel<String>(this, "sNumber"); add(new Label("message", "HelloWorld!")); add(new Label("result", sResult)); Form<?> form = new Form("form"); form.add(new TextField<String>("firstNumber", firstNumber)); form.add(new TextField<String>("secondNumber", secondNumber)); add(form); } } </code></pre> soo i have made this ` add(new Label("message", "HelloWorld!")); <pre><code> add(new Label("result", new Model(numb.getsResult()))); Form<?> form = new Form("form") ; form.add(new TextField<String>("firstNumber", new Model(numb.setfNumber()))); form.add(new TextField<String>("secondNumber",new Model(numb.setsNumber()))); add(form);` </code></pre> and i have a class that has 3 string fields and getters and setters and sii that much i have understood last comment explained some things maybe some one know how to fix this.

1. COI think it's best if you read this: https://cwiki.apache.org/WICKET/working-with-wicket-models.html#WorkingwithWicketmodels-DynamicModels Basically the two things that went wrong are that your label hasn't got a dynamic model and that you concatenate the values statically at creation time.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
