Java 在Wicket中禁用整个表单时出现异常

我在Wicket中有这个表单，当具有特定角色的用户登录时，它必须被禁用

在onConfigure（）方法中，我检查角色，如果它是不允许更改任何内容的角色，我将禁用表单：

getForm().setEnabled(!isSponsor());

但是，我得到了这个错误：

org.apache.wicket.markup.MarkupException: file:/bla/bla/bla/Panel.html: Component [printButton] (path = [1:work:child:bla:7:bla:fieldContainer:field:modal:content:form:Panel:printButton]) must be applied to a tag of type [button,input,a], not:  '<span wicket:id="printButton" id="printButtonb3">' (line 0, column 0)
