JSP compilation error with nested scripting variable





------- Additional Comments From d.gaffuri@reply.it  2002-09-11 11:45 -------
I've tried to compile a page with a custom tag extending BodyTagSupport and 
declaring a NESTED scripting variable named as the id attribute. In this case 
the scripting variable is initialized after doInitBody() but is never declared. 
It seems that another variable named _jspx_columnDescr_1, already declared at 
the beginning of service method, is declared instead, and the result generates 
two compilation errors.

/* ----  cb:column ---- */
browser.ViewColumn _jspx_columnDescr_1 = columnDescr;
browser.client.jsp.tag.Column _jspx_th_cb_column_1 = 
(browser.client.jsp.tag.Column) _jspx_tagPool_cb_column_value_name_id.get
(browser.client.jsp.tag.Column.class);
_jspx_th_cb_column_1.setPageContext(pageContext);
_jspx_th_cb_column_1.setParent(_jspx_th_cb_column_0);
_jspx_th_cb_column_1.setId("columnDescr");
int _jspx_eval_cb_column_1 = _jspx_th_cb_column_1.doStartTag();
if (_jspx_eval_cb_column_1 != javax.servlet.jsp.tagext.Tag.SKIP_BODY) {
  if (_jspx_eval_cb_column_1 != javax.servlet.jsp.tagext.Tag.EVAL_BODY_INCLUDE){
    javax.servlet.jsp.tagext.BodyContent _bc = pageContext.pushBody();
    _bc.clear();
    out = _bc;
    _jspx_th_cb_column_1.setBodyContent(_bc);
    _jspx_th_cb_column_1.doInitBody();
    columnDescr = (browser.ViewColumn) pageContext.findAttribute("columnDescr");
  }
  do {
    /* body */
    int evalDoAfterBody = _jspx_th_cb_column_1.doAfterBody();
    columnDescr = (browser.ViewColumn) pageContext.findAttribute("columnDescr");
    if (evalDoAfterBody != javax.servlet.jsp.tagext.BodyTag.EVAL_BODY_AGAIN)
      break;
  } while (true);
  if (_jspx_eval_cb_column_1 != javax.servlet.jsp.tagext.Tag.EVAL_BODY_INCLUDE)
    out = pageContext.popBody();
}
if (_jspx_th_cb_column_1.doEndTag() == javax.servlet.jsp.tagext.Tag.SKIP_PAGE)
  return;
_jspx_tagPool_cb_column_value_name_id.reuse(_jspx_th_cb_column_1);
columnDescr = _jspx_columnDescr_1;

The generated errors are:

Don't know if the two problems are related, so I add a comment instead of 
opening a new bug.

Thanks.
