I am aware of this. I just wanted to show that you sometimes cannot make use of the compact syntax in attributes, so you have to fall back to the angle-bracket-syntax.

Hi,

The compact syntax was introduced for increased readability and
compatibility with JSP expressions. Additionally, using the compact
syntax keeps your HTML valid, which helps IDEs to highlight ESP.

ok. thanks.

There are however cases, where the default syntax is the more compact
way to express something, e.g. if you want to have extended control
structures in the scriptlet.

<%
var value;
if (foo==bar) {
        value = "foo";
} else {
        value = "bar";
}
%>

<a href="http://${value}.com/";>

vs.

<a href="http://<% if (foo==bar) {%>foo<%} else {%>foo<%} %>">

don't confuse <%=...%> and <%...%>. These are not the same things and
(in ESP) ${...} is just a different notation for <%=...%>. So in the
above example, the comparison is

  <a href="http://<%= value =>.com/">

vs.

   <a href="http://${value}.com/";>

Hi all,

Hmm, I am getting unsure ... Why was the compact syntax "${...}"
introduced at all ? Was it to mimic Expression Language stuff ? Not
sure, whether we really need this in ESP.

If someone could enlighten me ?

-------------------------------------

I think we should re-open, as the compact syntax should extend the default syntax, not replace it.

esps not executed quite correctly

               Key: SLING-248

URL: https://issues.apache.org/jira/browse/ SLING-248

           Project: Sling
        Issue Type: Bug
        Components: Scripting
       Environment: windows xp, java 5
          Reporter: Michael Marth
          Assignee: Felix Meschberger
           Fix For: 2.0.0


I have an .esp with this code snippet:

posted by <a href="/microsling/content/blogs/main.html?poster=< %=resource.node.posterName%>"> <%=resource.node.posterName%></a> the first <%=resource.node.posterName%> does not get executed, the second does. I experimented a bit and think that <%= %> scripts embedded in an html attribute do not get executed.
