@Repeat(items=apps, var="app")
<li>
${app.clientId}<a href="$urls[app.clientId]" > auth</a>
</li>

that's my html code.

the $urls is passed by the Java class.

It complains compile error

Try this (make sure the Java class has got getUrls() defined):

${app.clientId}<a href="${urls[app.clientId]}" >

I am sorry to make this silly mistake. I have tried

${urls[app.clientId]}
${urls['${app.clientId}']}
{$urls[${app.clientId}]}

Look at the simplest case

@At("/")
public class Example {
private String message = "Hello";
private List<String> users = Arrays.asList("jilen");
private final Map<String, String> userMap = new HashMap<String, String>();
@Get
public void get() {
userMap.put("jilen", "foo");
}
public List<String> getUsers() {
return users;
}
public void setUsers(List<String> users) {
this.users = users;
}
public Map<String, String> getUserMap() {
return userMap;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}

<html>
<body>
<p>${message} from Sitebricks!</p>
@Repeat(items=users, var="user")
<div>${userMap}</div>

</body>
</html>

It will not compile.

But this html (access outside of @Repeat) works fine

<html>
<body>
<p>${message} from Sitebricks!</p>
@Repeat(items=users, var="user")
<div></div>
${userMap}
</body>
</html>

I think I find the reason. The @Repeat is a widget. It has no property expect for items and var.

So variables defined in Page class is not accessible.

Ahh inside a repeat you need to use:

__page.userMap

Because main var is now 'user'
