Just thought I would mention that I am having this problem as well. My content is doubled when inserted in code view but not when in wysiwyg mode.
I am having a problem in wysiwyg mode so I thought code view would work for me instead but I am having this issue so no luck for me here.
If anyone has a suggestion for my problem in wysiwyg mode let me know.
My problem in wysiwyg mode is more of an editor problem than a problem with Content Templater but maybe someone has a fix.
My problem is this. I have a small snippet that needs to be inserted on the same page several times and modified slightly each time.
When I insert it with content templater the first time all is well. However trying to insert it again is a problem because In the editor I can not move the courser outside of the div. So the new content goes inside of it and messes up my code. Here is an example.
This is the code snippet.
<div class="staffItem">
<div class="staffinfo">
<h1>Name</h1>
<p>Description<br /><a href="index.php?option=com_contact&view=contact&catid=6:it&id=1-first-last">Contact</a></p>
</div>
<div class="staffpic"><img alt="tep" src="uploads/images/tep.jpg" width="110" height="110" /></div>
</div>
When I try and insert another item under this one i get this.
<div class="staffItem">
<div class="staffinfo">
<h1>Name</h1>
<p>Description<br /><a href="index.php?option=com_contact&view=contact&catid=6:it&id=1-first-last">Contact</a></p>
</div>
<div class="staffpic"><img alt="tep" src="uploads/images/tep.jpg" width="110" height="110" />
<div class="staffItem">
<div class="staffinfo">
<h1>Name</h1>
<p>Description<br /><a href="index.php?option=com_contact&view=contact&catid=6:it&id=1-first-last">Contact</a></p>
</div>
<div class="staffpic"><img alt="tep" src="uploads/images/tep.jpg" width="110" height="110" /></div>
</div>
</div>
</div>
As you can see because I can not move the courser out of the first div it makes a mess of my code which gets worse each time I add an item.
So does anyone know how to move the courser out of the dive in the wysiwyg? I tried adding a break or two after the div as part of the template but this has problems as well as each time I add a item another break is put in so things are not evenly spaced.
