Hi, there is a lot of place in my project where this situation occurs. There
is one of them (I removed unnecessary code):
Main template with parameter / property "title" (the title meant to be
displaed in head section):
public class MainTemplate {
@Parameter(defaultPrefix="literal")
@Property
private String title;
.....
void setupRender() {
//on some pages title is auto generated
if (pathContainer.getProductDesc() != null) {
title += pathContainer.getProductDesc().getName() ;
}
//title can be defined in props file
if (title == null) {
title = messages.get("title-" +
pathContainer.getPageClass().getSimpleName());
}
//add suffix, here is modification which leads to exception on
pages with
predefined titles
title = title + " - TEST";
}
}
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>${title}</title>
.....
Inner template
public class ShopTemplate {
@Parameter(defaultPrefix = "literal")
private String title;
@Component(parameters={"title=prop:title"})
private MainTemplate template;
.....
}
<div t:id="template"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xml:space="preserve">
.....
</div>
Here is page with predefined title:
public class Addresses implements AjaxZoneComponent {
@Component
private ShopTemplate template;
......
}
<div t:id="template" title="My addresses"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xml:space="preserve">
....
</div>
As I understand the only way to pass a predefined literal value of title to
the MainTemplate is to add property in the page class Addresses :
public class Addresses implements AjaxZoneComponent {
@Component(parameters={"title=prop:title"})
private ShopTemplate template;
@Property
private String title = "My addresses";
......
}
Of course there are other workarounds (i.e. to define all titles in props as
mentioned before), but I think it's not expected behaviour.
