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. 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.

Choose witch Component to use by a String
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. I add div t:type=component1/divto a .tml file, component1 is the Component Class name. I try to add a method getComponentName() to the java file, then i can control which component to use, but i failed. Is their another way to do this? Thanks.
