As the title says,
When I try to modify and APP on a site with a custom CSS registered with CSSRegistration:
<SharePoint:CssRegistration name=”<%$SPUrl:~SiteCollection/Style Library/~language/Themable/icapapp.css%>” runat=”server” EnableCssTheming=”true” />
I get the error shown in the title (Exact error as an attachement)
So.. you can get around this on premises by utilising _layouts for me which is bad practice as you never know what an update will include and besides this on 365 so is a no go area. Or of course you don’t use custom themeable css… Which totally lets down the whole themeing concept.
Recap:
- Masterpage on main site has custom themeable css registered WORKS
- Add an App and configure
- App Properties page doesn’t load CSS due to cannot make cache safe URL error
- It is automatically trying to append the hive/~language url to the front
- Could this be a publishing error? SPUrl insufficient in this case?
- Due to site-appid.sharepoint.com address it is attempting to resolve using relative url?

Still makes me think is this a unintended side effect because of the App model or is it intended.
I am sending it in as an issue and I will await a response.
In the mean time I will investigate on other ways to achieve this, perhaps maybe a way to block APPs from attempting to load custom CSS for their configuration pages.
Thank you very much for the reply!
