@SSK: thanks for your feedback
>I have deleted the 'private' from the opening lines of cwsFolderGalleryPage.php (thanks to this thread), for the installation to work.
The private statement is a requirement for the SS 3.1.x series but does break code in the SS 3.0.x series. Just created a [url=https://github.com/cwsoft/silverstripe-cwsoft-foldergallery/tree/3.1.x]SS 3.1.x branch[/url] for my module to distinguish between 3.0.x and 3.1.x development more easily.
to Page.ss in my theme folder for the slideshow and naviation to work (SS 3.0.5, Firefox 20.0.1).
Strange. This should work out of the box via usage of the [url=https://github.com/cwsoft/silverstripe-cwsoft-foldergallery/blob/master/cwsoft-foldergallery/code/cwsFolderGalleryPage.php#l79]Requirements class.[/url].
>I'm not too sure about an upcoming upgrade to SS 3.1, it seems like many modules and plugins will need to be upgraded as well - I had to learn the hard way that many modules for SS 2.x do not work with SS 3.0.x 'out of the box', making them useless for anybody who is just getting to know Silverstripe and php, like me...
You are right. To avoid version conflicts, I setup three branches for the "cwsoft-foldergallery" module to support: [url=https://github.com/cwsoft/silverstripe-cwsoft-foldergallery/tree/2.4.x]SS 2.4.x[/url], [url=https://github.com/cwsoft/silverstripe-cwsoft-foldergallery]SS 3.0.x (master)[/url] and [url=https://github.com/cwsoft/silverstripe-cwsoft-foldergallery/tree/3.1.x]SS 3.1.x[/url].
