nevermind (obviously a hack since it will ignore showAction with appendCell, but it does the trick):

$.fn.fmatter.showlink = function(cellval, opts) {var op = {baseLinkUrl: opts.baseLinkUrl,showAction:opts.showAction, addParam: opts.addParam || “”, target: opts.target, appendCell:opts.appendCell, idName: opts.idName }, target = “”, idUrl; afterUrl = “”; if(!isUndefined(opts.colModel.formatoptions)) { op = $.extend({},op,opts.colModel.formatoptions); } if(op.target) {target = 'target=' + op.target;} if(op.appendCell){afterUrl=cellval;}else{afterUrl=op.showAction+'?'+op.idName+'='+opts.rowId;} idUrl = op.baseLinkUrl+afterUrl+op.addParam; if(isString(cellval)) { //add this one even if its blank string return “” + cellval + ““; }else { return $.fn.fmatter.defaultFormat(cellval,opts); } };
