Server side render problem with custom column

[PaceyIV]

In my config_local.php I have declared some custom column:

$config['cops_calibre_custom_column_list'] = array ("read", "pages");

They are defined in the database as:

1 | read | Letto | bool | 0 | 1 | {} | 0 | 0 | 4 | pages | Pagine | int | 0 | 1 | {"number_format": "{0:,}"} | 0 | 0 |

On my Kindle Touch (4th generation) and on Google Chrome with server side render enabled on all device ( $config['cops_server_side_render'] = ".") I get the 500 error code:

[Thu Aug 11 13:53:08.337531 2016] [:error] [pid 9746] [client 192.168.1.106:53728] PHP Fatal error: Cannot use object of type CustomColumn as array in /media/data/ebooks/cops/resources/doT-php/doT.php(94) : runtime-created function on line 160, referer: http://192.168.1.1/ebooks/index.php?page=2&id=G&db=0

I work around this issue by disable Server side render for Kindle 3. So far so good.

$config['cops_server_side_render'] = "Kindle\/1\.0|Kindle\/2\.0|EBRD1101|EBRD1201|cybook";

@slgray

is your Kindle still usable with client side rendering ? If yes, I'll remove it from config_default for the next revision.

With client side rendering on Kindle Touch (User Agent Kindle/3.0+) there are too many redraws of the page, and the selected item blinks for a while.

@seblucas It still works great with eink theme. My device is Kindle Paperwhite (UserAgent: "Mozilla/5.0 (X11; U; Linux armv7l like Android; en-us) AppleWebKit/531.2+ (KHTML, like Gecko) Version/5.0 Safari/533.2+ Kindle/3.0+") @PaceyIV maybe you can try eink theme.

I've tried eink them with client rendering and server side rendering: it works fine with both solution.
