I seem to be seeing this bug when I validate my JSPs that use runtime expressions in tag attribute values:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=302060

Unless I explicitly define all tag attributes with rtexprvalue="true" I get a "does not support runtiime expressions" warning every time I use a runtime expression for the tag attribute value.

Is there a patch or a workaround for this problem?

BigLeeH,

Sorry that you are seeing this issue. I could not replicate the issue on MyEclipse 10.6 version.

1. Can you please copy paste the Installation Details from MyEclipse > Installation Summary > Installation Details ?

2. If you are not on 10.6, can you please update to 10.6 and check if you still see the issue ?
The license you currently hold is valid for 10.6 too as our licenses are time based and not version based.

3. If you are still seeing issues on 10.6, can you please list out the steps in detail you are following for us to help replicate the issue at our end ?

Let us know how it works for you.

Let's see...

2. If you are not on 10.6, can you please update to 10.6 and check if you still see the issue ?

Done.

See attached zip file with a simple project I created.

It contains one tag file:

Code:

<%@ attribute name="whattosay" required="false" %> <%@ attribute name="whattosaynext" required="false" rtexprvalue="true" %> <div style='color:red' >    ${ whattosay }    ${ whattosaynext } </div>

... and one JSP:

Code:

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> <%@ taglib tagdir="/WEB-INF/tags/testtag" prefix="tt" %> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html>   <head>     <base href="<%=basePath%>">         <title>My JSP 'index.jsp' starting page</title>    <meta http-equiv="pragma" content="no-cache">    <meta http-equiv="cache-control" content="no-cache">    <meta http-equiv="expires" content="0">       <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">    <meta http-equiv="description" content="This is my page">    <!--    <link rel="stylesheet" type="text/css" href="styles.css">    -->   </head>     <body>     <tt:testtag whattosay="${'Hello, world' }" whattosaynext="${'.' }" />   </body> </html>

In the JSP the validator marks the value of the whattosay attribute with a warning --

Code:

"whattosay" does not support runtime expressions.

-- but does not mark whattosaynext. This strongly suggests that the validator is treating rtexprvalue as defaulting to false.

Let us know how it works for you.

BigLeeH,

Thank you for the details and the project.
I could replicate the issue at my end. I have filed a PR for the dev team to work on it.

Sorry for inconvenience caused.

BigLeeH,

This issue has now been fixed in release 10.7. You can use the Configuration Center to update to 10.7. Alternatively download the MyEclipse or MyEclipse Blue installer from our download page.

Note that the full installer for MyEclipse for Spring won't be available for a few weeks but the fix should be in the update available from the Configuration Center. I mention this because it looks, from your installation details, as though you may have a MyEclipse for Spring installation also.

Thanks again for reporting the issue.
