I have retested your fix and I am afraid that it still doesn't work correctly :(\r\n\r\nit works fine under Chrome and IE, how ever FireFox (lates version 36.0.1) still throws error :\r\n\r\nTypeError: this._styles.rules is undefined gridstack.js:487:19\r\n\r\nwhich refers to :\r\n...\r\nwhile (this._styles.rules.length) {\r\n...\r\n\r\nwhen cell_height(val) is called.\r\n\r\nAny thoughts on that ?\r\n\r\nThanks,\r\nKarol\r\n"}}
