Further to this point:
In afterCompose:

super.afterCompose();
Components.wireVariables(this, this); //autowires variables
Components.addForwards(this, this); //adds event forwarding

Just figured this out myself. Wish it was documented a little better. The other thing I found was to watch accessors – if you’ve set some attributes, then defining setAttributeName type methods does bad things…

Simple enough, just access the component:

myMacro.myLabel.setVisible(false)

or create an method or event.

Nice Article !!

What if I want to handle macrocomponents in my composer.
e.g. I want to change text or hide the label dynamically in macro components.

If you’re using zkgrails 1.0 series try to define the composer using this syntax:

apply="com.nmtcr.composers.security.loginComposer"

Notice the lower case ‘l’ in login and don’t use ${}. And don’t forget to join ZKGrails User Group, you’ll get better and faster answers there

felipe,

I am investigating zk grails and have a quick question if you have a moment. In the apply attr I am placing fully-qualified name of the composer as you have in several of your examples. however, when I ran the app I am getting this stacktrace below stating that bean cannot be found even though it actually works (the composer code is actually getting executed).

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named ‘com.nmtcr.composers.security.LoginComposer’ is defined

Hi!

What if, when I have a macro something like that:

…..

So it’s like a grid, the listview can contain any kind and number of elements (a button has a forward, but the proper method won’t be called), in that case should one traverse the children recursively? Or is there better way?

Hi Rajesh,

You can handle the events on any composer that your macro is within. Just like any other component.

good one.but is there any way to use different composer for macro and handling its events in that composer? rather than to handle events of macro components in composer of main zul file.
