ExtJS4 textfield msgTagert=side显示和以前不一样

 

1. 问题现象多说无益，有图有真象：）
   
   
   
2. 详细代码可以看, ExtJS 包中的例子:/examples/form/dynamic.html
   Example: Form 1 - Very Simple
3. Fixed:请去掉logger.info这一行，这个logger是我自己定义的仿造日志货
   

   if (Ext.versions.extjs.getMajor() == 4) {
   	Ext.Loader.require('Ext.layout.component.field.Field', function() {
   		logger.info('修复form.Field在msgTarget=side时的width显示变化的bug');
   		
   		Ext.layout.component.field.Field.prototype.errorStrategies.side.getErrorElWidth = function(owner) {
   			if (owner.autoFitErrors && owner.hasActiveError()) return owner.errorEl.getWidth();
   
   			if (!this.errorElWidth) {
   				var errorEl = owner.errorEl,
   	    			display = errorEl.getStyle('display');
   	    		if (display == 'none') errorEl.setDisplayed(true);
   	
   	    		this.errorElWidth = errorEl.getWidth();
   	    		if (display == 'none') errorEl.setDisplayed(false);
   			}
   			
   			return this.errorElWidth;
   		};
   		
   		Ext.layout.component.field.Field.prototype.errorStrategies.side.prepare = Ext.Function.createSequence(
   			Ext.layout.component.field.Field.prototype.errorStrategies.side.prepare,
   			function(owner, info) {
   	            if (info.autoWidth) info.width += this.getErrorElWidth(owner);
   			}
   		);

               info.insets.right += this.getErrorElWidth(owner);
           };
   	});
   	
   }
