Two Menu Components
Hi All
I need some advice on how to get two menu components to talk to each
other. The fist component is a top menu with a whole lot of links, when
an action link is fired(from the first menu component) I want to pass a
parameter string to the second component (sub-menu) which will render
based on the parameter it's been passed to it.
So in other words second menu component is dependent on the first.
Its pretty much high level but some advice would be useful. Perhaps a
component listener of some sort?
Any ideas ?
Thanks
Eldred

Thanks Donf and Otho, my two menu components work like a charm. I used
the MultiZoneUpdate method. I now have a very interactive menu system !

There are 2 ways to refresh your menus:
1. return MyMenu to refresh the whole things of your menu component
2. return content block of your submenu, and you can return a
MultiZoneUpdate anyway.

Hi,
this is wild guess, but take a look at the environment? You can push, pop
and peek objects that are in the environment, shared by all enclosed
components.

Take a look at the @Environmental annotation. It is used, for example,
by fields to check if it has a validation error. They do that by
getting a ValidationTracker instance from the environment, which is
pushed by the Form component while starting its rendering.

Hi Guys
No problem, thanks Otho and donf yang for helping a newbie at Tapestry.
Am still trying get my head around how to pass data between components
(not same as pages) ie how to pass data from one component to another.
Let me be more precise:
If I use the @Component annotation then my second menu component it has
be nested inside first <t:mainMenu><div class="sidemenu"/></t:mainMenu>
there you can pass a string to submenu provided that its enclosed inside
MainMenu component, however would not work if my two menu components sit
independently from each other inside my Layout component. Apologies is I
did not explain myself clearly enough. Here is my Layout.tml code
fragment:
...
<!--Main menu top-->
<!--header-->
<t:mainmenu myStringParameter="Link1,Link2 Link3..."/>
<div style="clear:both;"/>
<!-- Body -->
<div id="bd">
<div id="yui-main">
<div class="yui-b">
<div id="bd">
<t:body />
</div>
</div>
</div>
<div class="yui-b">
<t:sideMenu/>
</div>
</div>
<!-- end body -->
<div style="clear:both;"></div>
...
When the event hander is called ie onAction(String context) from
MainMenu.java I want to be able to pass that string from the onAction
method (MainMenu.java) to another method called
setSelectedMenuItem(String context) inside SideMenu.java without getting
a NullPointerException. If I use @Component annotation then I need to
nest <t:mainMenu><div class="sidemenu"/></t:mainmenu> then it will work.
But because my sidemenu component sits further down in my Layout.tml
page, how can I do this ?
Thanks again for the assistance.

Oops, sorry. My bad.
This doesn't work with components in this way.
If you want to update with Ajax I suggest you try donf jangs solution.
The
following works on full page refresh.
You need to have MainMenu and SideMenu as components in your Layout.java
Layout.java
@Component
private MainMenu mainMenu;
@Component
private SideMenu sideMenu;
Object setupRender()
{
sideMenu.setSelectedMainMenuItem(mainMenu.getSelectedMenuItem());
....
return null;
}
MainMenu.java
@Persist
private String selectedItem;
@Property
private List<String> menuItems = Arrays.asList("home", "about", "help");
@Property
private String currentMenuItem;
public String getSelectedMenuItem()
{
return selectedItem;
}
Object onActionFromMyMenu(String context)
{
selectedItem = context;
return null;
}
MainMenu.tml
...
<ul>
<t:loop source="menuitems" value="currentMenuItem">
<li><a t:type="actionLink" t:id="myMenu"
context="currentMenuItem">${message:${currentMenuItem}-label}</a>
</t:loop>
</ul>
MainMenu.properties
home-label=Start
about-label=About
help-label=Help
SideMenu.java
@Persist
private String selectedMainMenuItem;
public getSelectedMainMenuItem()
{
return selectedMainMenuItem;
}
public setSelectedMainMenuItem(String value)
{
selectedMainMenuItem=value;
}
The rest with the blocks can stay as it is in the first post.
If you don't write explicit getters and setters like I did in this
second
example, it won't compile, since the getters and setters are only
created at
runtime by Tapestry when using the @Property annotation. Sorry for being
so
rash. I hope this helps, and as I said if you want Ajax, look at donf
yangs
code.

You need to have MainMenu and SideMenu as components in your Layout.java

The rest with the blocks can stay as it is in the first post.
If you don't write explicit getters and setters like I did in this second
example, it won't compile, since the getters and setters are only created at
runtime by Tapestry when using the @Property annotation. Sorry for being so
rash. I hope this helps, and as I said if you want Ajax, look at donf yangs
code.

RE: Two Menu Components

Hi Otho
Thank you for the feedback, I am trying this example, but notice that I
get a transformation exception if I inject my component as per your
example. Complaining about it not having a serviceID ?
Using T5 5.1.0.5
How do I provide a serviceID to ComponentResourcesInjectionProvider ?
Thank you

Create an eventhandler in your MainMenu component which fires on select
and
gives the selected menuitem as context.
For example
class MainMenu
@Inject
private SideMenu sideMenu;
Object onActionFromYourMenu(String context)
{
sideMenu.setSelectedMainMenuItem(context);
return null;
}
class SideMenu
@Property
@Persist
private String selectedMainMenuItem;
@Inject
private Block whateverBlock;
@Property
@Persist
private Block displayBlock;
Object setupRender()
{
if(selectedMainMenuItem.equals("whatever")
displayBlock = whateverBlock;
...
return null;
}
SideMenu.tml
<div class="sidemenu">
<t:delegate to="displayBlock"/>
</div>
<t:block t:id = "whateverBlock">
<ul>
<li>Whatver has to be done</li>
<ul>
</t:block>
