关于velocity中的template应用出错的问题

index.vm中的相关代码：
[code:1]
………………
<FORM NAME="post" METHOD=POST ACTION="addpost.action">
#tag( Label "label=label test" "name='label name'" "value=scalar" )
<INPUT TYPE="submit" value="提交" >
</FORM>
………………
[/code:1]

出错信息如下：
[code:1]

[/code:1]
其中，第9行是指
[code:1]
#tag( Label "label=label test" "name='label name'" "value=scalar" )
[/code:1]

请问可能是哪儿的问题，没有修改过template

macro不是这么用的
假设定义一个macro
[code:1]#macro(mytag $name $value)
   Name: $name  Value: $value
#end[/code:1]

使用的时候应该是类似：
[code:1]#mytag ("myname" "myvalue")[/code:1]
解析出来就是：
[code:1]Name: myname Value: myvalue[/code:1]

回到你的问题，
[code:1]#tag( Label "label=label test" "name='label name'" "value=scalar" ) [/code:1]

你的第一个参数不是一个合法的变量（例如$xxx)，也不是一个合法的值(比如34,"aaa")，报错是应该的，你应该去找找你的macro的定义，我想估摸着你把tag拿掉把Label拿出来估计就好了

我用的是velocity1.4，好象在1.4中对这种写法有了新的规定，这种写法在1.4中是非法的，细节还在求证中。

我是在webwork2环境下用，我是想用webwork2.jar下面的 /template/xhtml/text.vm,刚才的那个#tag(Label "name=xxxx" "value=xxx")的写法，我是照webwork2的参考来的

webwork2.0 xwork1.0＋velocity-dep-1.4-是有冲突。
见http://janyou.blogdriver.com/index.jsp
解决的方法之一是修改velocity 1.4的源码
[code:1]class:  org.apache.velocity.runtime.parser.Parser
method: final public SimpleNode Directive() throws ParseException {
    …………
         argType = DirectiveArg();
                if (argType == ParserTreeConstants.JJTWORD)
                {
                    if (doItNow && argPos == 0)
                    {
                        /* if a VM and it's the 0th arg... ok */
                        ;
                    }

                    else if( t.image.equals("#foreach") && argPos == 1)
                    {
                        /* if a foreach and it's the 2nd arg ok */
                        ;
                    }
                    //added by janyou-->
