<a/> tags removed

Hi! I'm using your SimpleLink plugin as a CKEditor feature at freepost.
When I call the method .setData(...) on a ckeditor instance, all the anchors are removed. For example whenever I try to copy a DIV html into a editor like this

aEditor.setData($("<div/>").html())

all A tags are replaced by a simple text. This is probably a problem with CKEditor's Advanced Content Filter, since setting allowedContent=true in aEditor seems to work fine.
You can test the behaviour by posting a comment here and later clicking on "Edit".

Any ideas?

Apparently also injecting the HTML directly into the textarea doesn't work; links are removed. Can you confirm this?

<textarea id="xxxxx" name="xxxxx" class="ckeditor" rows="1" cols="1"><a href="http://freepo.st" target="_blank">freepost</a></textarea>

It looks like that the issue is resolved when changing this code

editor.addCommand( 'simplelink', new CKEDITOR.dialogCommand( 'simplelinkDialog' ) );

to this

editor.addCommand( 'simplelink', new CKEDITOR.dialogCommand( 'simplelinkDialog', {
    allowedContent: "a[href,target]"
}));

in ./ckeditor-simple-link-plugin/plugin.js. However, I don't know CKEditor API and I'm not sure whether this is the correct way of solving the problem, or just a hack. Ideas?

I looked at the docs and according to the example in http://docs.ckeditor.com/#!/guide/plugin_sdk_integration_with_acf, your fix it's the correct way for marking tags as allowed.

To add the tag to the editor contents in a correct and automatic way, you need to extend the abbrDialog command definition when calling the CKEDITOR.dialogCommand constructor:
new CKEDITOR.dialogCommand( 'abbrDialog', { allowedContent: 'abbr' } );
