Dynamic component usage example

[Макаров Роман <ro...@kupivip.ru>]

Can someone please provide an example of using Dynamic component?

The framework is really complicated and there is lack of documentation.

I have tested the component without success. The code below giving me unrendered output.

I very appreciate your help.

public class TrackerDynamic extends Tracker {


    @Property
    private DynamicTemplate dynamicTemplate;

    public String getTestString() {
        return "uuuuuuuu";
    }

    @Override
    void beginRender() {
        super.beginRender();
        dynamicTemplate = new DynamicTemplate() {
            @Override
            public RenderCommand createRenderCommand(final DynamicDelegate delegate) {
                return new RenderCommand() {
                    @Override
                    public void render(MarkupWriter writer, RenderQueue queue) {
                        delegate.getComponentResources().storeRenderVariable("testvar", "test VALUE");

                        queue.startComponent(delegate.getComponentResources());

                        writer.write("asd ${testvar} ${getTestString()} <t:textfield t:id=\"asdf\" />");
                        queue.endComponent();
                    }
                };
            }
        };
    }
}

the tml is

<t:Dynamic template="prop:dynamicTemplate"></t:Dynamic>

Ohh, found your comment :)

// if you want this to come from a string you might need to
 // implement a StringResource by extending AbstractResource

Thanks for your help!

Thanks a lot!

Now, the problem is that I need to get template from the database, not a file (is not Dynamic component designed especially for that?)

Is the Resource interface can be implemented to represent a file? The openStream() method looks fine, but what about all other methods, which are file-oriented. Also, the to implementations in the framework both represents files..

You'll need to use the DynamicTemplateParser
