Hi,
I am implementing a component hence I can't implement the
IPageRenderListener - it is only for pages.
Besides I was wrong about the theory having my components sharing some
object and being in same namespace.
Obviously they are on different pages and by that they have different
keys in the sessionRecorder.
I think I have some other (local) problem, because now I have the
component working on two different pages, but not on this third
_bastard_ of a page :-)
I have to look into the differences on these pages.
Regards

Oh, your code is from a component! Sorry, didnt't get this first.
Try implementing PageRenderListener and implement pageBeginRender( PageEvent
event ).
that works for me.

Hi,
I was wrong when I told that I got the exception everytime.
Actually the
solution about implementing prepareForRender works on the
first page I
render that has my component, but the second page that uses the exact
same component throws the exception about the page was committed().
I think I have narrowed my problem down to the fact that the same
component is used in more than one page. It has the side effect that
they are in the same namespace (pagename.componentname combined gives
the name), hence they share some set of pagerecorders or
other tapestry
related objects.
That could be the reason why I have the problem.
Anyone of you ever had a similiar problem? and how did you solve it?
I think I could wrap the use of the component into another component,
but that can't be the way to do this, right?

That's funny. I'm doing the exact same thing in my 3.0-Apps
and it works
very well. The only difference I can see is that I call
super.prepareForRender() first. Perhaps you could try this.

Subject: Howto initializing a persisted property - only once
Hi,
I am struggling a bit with initializing a persisted property
of a component
I need something like this:
<property-specification name="userStoryFilter"
type="com.nordija.planb.domain.util.UserStoryFilter"
initial-value="new
com.nordija.planb.domain.util.UserStoryFilter() " persistent="yes"/>
Except that the effect of initial-value is that it will be
initialized
everytime the page the component is contained inside is put
back into
the page pool.
I need to do a initialize once.
I have tried manually by writing:
protected void prepareForRender(IRequestCycle cycle) {
if (getUserStoryFilter() == null) {
setUserStoryFilter(new UserStoryFilter());
}
super.prepareForRender(cycle);
}
But it generates a runtimeexception:
Page recorder for page MyPage is locked after a commit(), but
received a
change to property userStoryFilter of component MyPage/myComponent.
Do you have any suggestions on how to initialize a
persisted property
the first time the component is rendered on a specific page?
I'm using Tapestry 3.0.3.
