Help Error run Struts in VAJ 4 "cant remove Attributes from request scope" remain
Hi, Geoff and Mark and all
Thank you for answer my question on how to use struts in VAJ
I got it run but with a error
Server caught unhandled exception from servlet [jsp]: cant remove
Attributes from request scope
I followed the e-mail Geoff sent out on 8/21/2001 with
Replace the following lines in the doEndTag() method in the FormTag
class:
pageContext.removeAttribute(Constants.BEAN_KEY,
PageContext.REQUEST_SCOPE);
pageContext.removeAttribute(Constants.FORM_KEY,
PageContext.REQUEST_SCOPE);
with the following:
pageContext.getRequest().removeAttribute(Constants.BEAN_KEY);
pageContext.getRequest().removeAttribute(Constants.FORM_KEY);
The problem remains, is there anything else I need do ?
Julia

For the record, my mistake was in use the "scope" attribute instead of
the
"toScope" attribute.
