AW: AW: How to create component without binding?
I took a component binding to a panelGrid for testing and it worked quite
well but the dynamically created components appear only once in the page. If
I access the page a second time or reload the they disapper.
The code I used is copied from here (the last entry):
http://forums.java.sun.com/thread.jspa?threadID=555626&messageID=2816029
What do I have to do that the components appear every time? I use facelets,
does this have any impact?
Many thanks in advance and best regards,
René

Hi,
the tag should render nothing but just the children
if no "style" or "styleClass" attributes are present.
So
should do.
see:

That sounds good ;)
How can I realize this?
Like this?
Does a component exist that acts just like a container for other components
but itself doesn't get displayed? This way it would be possible to make a
binding to this component without the need to display the component.

Then you'll need to do a binding for the ViewRoot ;)
How would JSF know where to put your components, if you don't have
them in the template?

AW: How to create component without binding?
First thanks for the many answers in just one hour :-)
Why do I need a binding to do this? If I need a binding to for example a
panelgroup this means that on the page the panelgroup gets rendered although
I don't need (or want) it.
Lets assume I want to create dynamically several outputlinks. With a
panelgroup binding they are all inside a panelgroup. Why cannot I just hang
the outputlinks in UIviewroot and skip all the binding stuff?

What you want to do is do a binding for panelGroup
and then add children to this panelGroup - with this you can create
extra components.
code snippet (not compiled except in my head ;):
public UIComponent getPanelGroup()
{
HtmlPanelGroup panelGroup = new HtmlPanelGroup();
panelGroup.getChildren().add(new HtmlInputText());
panelGroup.getChildren().add(new HtmlOutputText());
...
return panelGroup;
}

How to create component without binding?
Hello @all, I would like to create dynamically inside a backing bean some components. Looking around in the net I found only solutions that create a binding to a component, for example: ... This means that I always need an existing component like panelGroup for creating with a binding some components. How can I create dynamically components without using a binding (and in the end an extra component)? Thanks and best regards, René Ott
