Hello,

In version 5.2.2, we were able to update casloginview.html to get request.queryString.  


However, in new version 5.2.3, we are getting
template parsing error.  below is cas.log and casLoginView.html

Is this there a bug in 5.2.3, getting request.queryString. ?



>>  casLoginView.html

<!DOCTYPE html>
<html xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout" layout:decorate="~{layout}">

    <title th:text="#{cas.login.pagetitle}"></title>
 
</head>

    <div layout:fragment="content">   
        <div class="box-hdr">Sign In <span style="color:#fcaf25">|</span> <a th:href="${@environment.getProperty('post.createUrl')+'?'+#strings.defaultString(#request.queryString,'')}">Create Account</a> </div>

Sounds like a thymeaf issue


TemplateProcessingException: Access to request parameters is forbidden in this context. Note some restrictions apply to variable access. For example, direct access to request parameters is forbidden in preprocessing and unescaped expressions, in TEXT template mode, in fragment insertion specifications and in some specific attribute processors.
