I just experienced a problem using the cool CKE Bootstrap Skin (https://github.com/Kunstmaan/BootstrapCK4-Skin) after the upgrade to fixpack 2 these days. I just wanted to create a new post here as I saw: no CKE anymore to see in my XPage 

Even the installation of the lates version from Github did not fix this issue. As I am not familiar enough to troubleshoot this issue I just removed the skin wherever I used it in my Bootstrapped applications *sigh*

So if you use e.g. a version of my FileSilo or any other apps from me using Bootstrap please check if they work after the upgrade. Otherwise remove the Dojo-attribute from the richtext control called "skin".

EDIT

I saw this tweet this morning and the comments point out that info, too: https://twitter.com/BGleesonIE/status/502749076497391617

And yes, the line

CKEDITOR.skins.add( 'BootstrapCK-Skin', (function()

is the one that causes the error so commenters may be right. Per Lausten linked me to this one and this is still working: http://ckeditor.com/forums/Skins-and-Icon-Sets/BootstrapCK-Skin

But not enough

The Dojo attribute "toolbarType" with the value "Full" doesn't work anymore, too. I miss tools such as styles (cite, code, typewriter stuff) and the source tab. Per Lausten also found another issue: http://per.lausten.dk/blog/2014/08/xpages-and-domino-9-0-1-fp2-upgrades-to-ckeditor-and-dojo.html

The proof

I just reverted one of my servers back to 901FP1 - and now the Richtext Control works like a charm though I cannot use the Bootstrap-Skin that Per pointed out.

See what the differences are:

This is with FP1

This is with FP2

This is what my implementation looks like:

<xp:inputRichText id="inputRichText1"
                                value="#{document1.postBody}" htmlFilter="identity"
                                htmlFilterIn="identity">
                                <xp:this.dojoAttributes>
                                    <xp:dojoAttribute name="width"
                                        value="900">
                                    </xp:dojoAttribute>
                                    <xp:dojoAttribute name="toolbarType"
                                        value="Full">
                                    </xp:dojoAttribute>
                                    <xp:dojoAttribute
                                        name="extraPlugins" value="autogrow">
                                    </xp:dojoAttribute>
                                    <xp:dojoAttribute name="skin">
                                        <xp:this.value><![CDATA[#{javascript:return "";
return @ClientType().equals("Web") ? "BootstrapCK-Skin,/"+database.getFilePath()+"/bscke/" : ""}]]></xp:this.value>
                                    </xp:dojoAttribute>
                                </xp:this.dojoAttributes>
                                <xp:this.dojoType><![CDATA[#{javascript:return "";
return @ClientType().equals("Web") ? "org.openntf.filesilo.CKEDITOR" : ""}]]></xp:this.dojoType>
                            </xp:inputRichText>

As you can see I deactivated the usage of the Bootstrap skin.

Conclusion

After some dabbling and testing and also with the help from the community (esp. Per) I now can resume the update with the following:

• You can use Fixpack 2 if you adapt the changes to the Dojo attributes to your Richtext controls
• You can use the Bootstrap skin (see link above)
• You can both use the attributes "toolbarType" and "toolbar" without getting errors to be compatible with 9.01FP1 and FP2
• You can set the toolbar options to valid values as "Slim", "Medium", "Large" and "Full"
• You can even use the new spell checker (the dialog is also skinned if you use the Bootstrap skin)

After all: a lot of hassle for nothing - if you know how or you know someone who knows it 

I found a workaround to keep CKEditor working with FP1 and FP2 (FP1 is without a custom skin though)
