I tried this approach. Is this means I must put all my components in a page. Is their a performance problem if i have many components in one page? How to pass parameter to the component I get in this way.

I've used this approach for plugin-style apps where the components to use for a given data type are determined at runtime and can be "plugged-in". And that's exactly the approach used by BeanEditForm, BeanEditor, Grid and BeanDisplay (except they use blocks instead of components directly, but this doesn't make almost any difference). -- Thiago H. de Paula Figueiredo Independent Java, Apache Tapestry 5 and Hibernate consultant, developer, and instructor Owner, Ars Machina Tecnologia da Informação Ltda. http://www.arsmachina.com.br - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Choose witch Component to use by a String
You can use ComponentSource to grab other pages, and then grab components off of those pages. I've used this approach for plugin-style apps where the components to use for a given data type are determined at runtime and can be "plugged-in".

If there are too many known components, I don't want to put so many components in on page. I have another thought. Can I create a new component, and based on a String parameter, render this component as another known component. (Like a page forward to another page). or, is there a way to get an instance of a Component using java code at runtime.

> I want to use a component in a page, but i don't know which to use, > I only know a String at Runtime, How can I do this. http://tapestry.apache.org/principles.html Principle 1 – Static Structure, Dynamic Behavior You can't choose your components at runtime. Although, if you have a set of known components that you want to choose from you can put your components in and load the block by id.
