ICEfaces抄袭PrimeFaces

ICEfaces涉嫌抄袭PrimeFaces

ICEfaces 3发布后，本来我是很激动的，以为这是一个伟大的版本。但是，PrimeFaces的同行们发现了ICEfaces抄袭了PrimeFaces的部分代码。ICEfaces的行为真令人失望！

由于PrimeFaces和ICEfaces都是开源产品，因此抄袭在法律上没有问题。但是在道德上，则无法过关。抄袭的代码对比如下：

一、PrimeFaces PanelRenderer

四、IceFaces Panel.js

/** *  Panel Widget */ice.ace.Panel = function(id, cfg) {    this.id = id;    this.cfg = cfg;    this.jqId = ice.ace.escapeClientId(id);     if(this.cfg.toggleable) {        this.toggler = ice.ace.jq(this.jqId + '_toggler');        this.toggleStateHolder = ice.ace.jq(this.jqId + '_collapsed');        this.content = ice.ace.jq(this.jqId + '_content');         this.setupToggleTrigger();    }     if(this.cfg.closable) {        this.visibleStateHolder = ice.ace.jq(this.jqId + "_visible");         this.setupCloseTrigger();    }     if(this.cfg.hasMenu) {        this.visibleStateHolder = ice.ace.jq(this.jqId + "_visible");         this.setupMenuTrigger();    }     if(!this.cfg.visible) {        ice.ace.jq(this.jqId).css('display','none');    }} ice.ace.Panel.prototype.toggle = function() {    if(this.cfg.collapsed) {        this.toggler.removeClass('ui-icon-plusthick').addClass('ui-icon-minusthick');        this.cfg.collapsed = false;        this.toggleStateHolder.val(false);    }    else {        this.toggler.removeClass('ui-icon-minusthick').addClass('ui-icon-plusthick');        this.cfg.collapsed = true;        this.toggleStateHolder.val(true);    }     var _self = this;     this.content.slideToggle(this.cfg.toggleSpeed,        function(e) {            if(_self.cfg.behaviors) {                var toggleBehavior = _self.cfg.behaviors['toggle'];                if(toggleBehavior) {                    toggleBehavior.call(this, e);                }            }        });} ice.ace.Panel.prototype.close = function() {    this.visibleStateHolder.val(false);     var _self = this;     ice.ace.jq(this.jqId).fadeOut(this.cfg.closeSpeed,        function(e) {            if(_self.cfg.behaviors) {                var closeBehavior = _self.cfg.behaviors['close'];                if(closeBehavior) {                    closeBehavior.call(this, e);                }            }        }    );} ice.ace.Panel.prototype.show = function() {    ice.ace.jq(this.jqId).fadeIn(this.cfg.closeSpeed);     this.visibleStateHolder.val(true);} ice.ace.Panel.prototype.setupToggleTrigger = function() {    var _self = this,    trigger = this.toggler.parent();     this.setupTriggerVisuals(trigger);     trigger.click(function() {_self.toggle();});} ice.ace.Panel.prototype.setupCloseTrigger = function() {    var _self = this,    trigger = ice.ace.jq(this.jqId + '_closer').parent();     this.setupTriggerVisuals(trigger);     trigger.click(function() {_self.close();});} ice.ace.Panel.prototype.setupMenuTrigger = function() {    var trigger = ice.ace.jq(this.jqId + '_menu').parent();     this.setupTriggerVisuals(trigger);} ice.ace.Panel.prototype.setupTriggerVisuals = function(trigger) {    trigger.mouseover(function() {ice.ace.jq(this).addClass('ui-state-hover');})            .mouseout(function() {ice.ace.jq(this).removeClass('ui-state-hover');});}

ICEsoft公司在开发ACE组件集时，把PrimeFaces的代码直接复制过来，然后修改包名和类名，其它的代码都是照搬。这种行为真丢脸。

结论：ICEfaces的行为让人及其失望，用PrimeFaces的开发者的一句原话作为本文的总结：“您可以复制我们的代码，但您永远也拿不走我们的激情！”。
