RE: Struts forms and JSP components/templates
Title: RE: Struts forms and JSP components/templates That just specifies the scope where the form bean is stored. If you look at the doStartTag method in the FormTag.java source, it contains a few lines that look something like this: pageContext.setAttribute(Constants.BEAN_KEY, bean); Those types of calls are what causes the problem. Specifically, when I try to include an html:textarea tag in my component, I get this error when I access the page: [ServletException in:/contentForm.jsp] Cannot find bean under name org.apache.struts.taglib.html.BEAN' javax.servlet.jsp.JspException: Cannot find bean under name org.apache.struts.taglib.html.BEAN at org.apache.struts.taglib.html.TextareaTag.doStartTag(TextareaTag.java:146) ... -- Tim Moore / Blackboard Inc. / Software Engineer 1899 L Street, NW/ 5th Floor / Washington, DC 20036 Phone 202-463-4860 ext. 258 / Fax 202-463-4863 -Original Message-From: Shunhui Zhu [mailto:[EMAIL PROTECTED]]Sent: Monday, May 07, 2001 6:15 PMTo: [EMAIL PROTECTED]Subject: RE: Struts forms and JSP components/templates I think the scope of the form is specified in struts-config.xml, you can put it in session scope.

RE: Struts forms and JSP components/templates
I think the change from page to request was alread made for html:form. Get the latest Struts from CVS.
