Subject [jira] [Commented] (WW-3828) FreeMarker dynamic attributes cannot be boolean
Date Wed, 30 May 2012 08:13:23 GMT

    [ https://issues.apache.org/jira/browse/WW-3828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13285489#comment-13285489

zhouyanming commented on WW-3828:
---------------------------------

it works in my test if I add code text.ftl
<#if parameters.autofocus?default(false)>
autofocus="autofocus"<#rt/>
</#if>

<@s.textfield theme="simple" name="username" autofocus=true/>
will render
<input type="text" name="username" value=""autofocus="autofocus" id="username" autofocus="true"/>

the side effects is there is a needless autofocus="true" generated by dynamicAttributes 
if you want fixed this problem,you should make autofocus as stardard attribute of org.apache.struts2.components.UIBean,like
required.
