I just created a module and I put this in my layout file:


    <?xml version="1.0"?>
    <layout version="0.1.0">
    	<filteredproducts_index_index>
    		<reference name="root">
    			<action method="setTemplate">
    				<template>page/2columns-left.phtml</template>
    			</action>
    		</reference>
    		<reference name="content">
    			<block type="filteredproducts/myblock" name="myblock" template="test.phtml"/>
    		</reference>
    	</filteredproducts_index_index>
    </layout>

Now for some reason, no mather what block I put there inside my reference name="content" tag. The block is shown twice.

test.phtml:

    <?php
    	echo "test";
    ?>

The text shown at the page is testtest. 
So the content must be loaded two times for some reason I just can't seem to figure out how.
Any help appreciated.
