This Tapestry component library implements the Facebook XFBML async javascript library. It will also write OpenGraph meta tags.

Currently to use the components you need to build the source then add the following to your pom file.

     <dependency>
        <groupId>com.trsvax</groupId>
        <artifactId>tapestry-facebook</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>


To use the tags on a page you'll need at least the <t:fb.asyncInit t:id="fbinit"/> element in your page/layout file and
something like the following in your java file.

    @Property
    private FBInit fbInit;
    
    @SetupRender
    void setupRender() {
    	fbInit = new FBInit();
    	fbInit.setAppID("your facebook app id");
    	fbInit.setCookie(true);
    	fbInit.setStatus(true);
    }
   
Then

<t:fb.like />

which by default has the following events

	void onEdgeCreate(@RequestParameter("url") String url) {
		logger.info("edge create {}",url);
	}
	
	void onEdgeRemove(@RequestParameter("url") String url) {
		logger.info("edge remove {}",url);
	}
	
If you want OpenGraph tags

@Environmental
private FBAsyncSupport fbAsyncSupport;

@SetupRender
void setupRender() {
	Tags tags = new Tags();
	tags.setSomeStuff();
	fbAsyncSupport.setTags(tags);
}
