Re: onBeforeRender vs. prepareForRender

[Stefan Simik]

Thank you both guys, 

all works fine now :)

The problem was, that I was using method "prepareForRender()",
instead of the "onBeforeRender()".

Thanx boys

Re: onBeforeRender vs. prepareForRender

[Johan Compagner]

prepareForRender is only called on the Page or Component that is the target
itself for rendering (so the begin target)
prepareForRender is not meant to be overridden and called from the outside
world as far as i can see

The hook is onBeforeRender (that is called through a call that originates
from a Page.prepareForRender())

Re: onBeforeRender vs. prepareForRender

[Stefan Simik]

One additional question,

is it valid to change to component hierarchy in these methods ?

I tried it, but it didnt work:



SHORT EXAMPLE:
-

AjaxFallbackLink updateLink = new AjaxFallbackLink("updateLink") {

  @Override
  public void prepareForRender() {
super.prepareForRender();

// if some condition true -> render additional attribute
if (isUpdateProcessRunning()) {
add(new 
StyleAttributeAppender("text-decoration: none;"));
}
  }
};


 and result was, that no STYLE attribute was rendered.

But when I write:
updateLink.add(new StyleAttributeAppender("text-decoration: none;"));
then, the STYLE attribute is rendered.


I cannot find out, what I am doing wrong here..

Thanks a lot.

onBeforeRender vs. prepareForRender

[Stefan Simik]

Hi guys,

I would like to ask, 
what's the difference between these 2 methods:
  onBeforeRender vs. prepareForRender
and when it is appropriate to use the first or second.

Thanks a lot
