Re: Why Components in Loop are the only one instance? What should I do?

It sounds like you need to work out a communication mechanism between your component and it's container. Presumably you are passing your parameters to your component via a property binding. What you probably want to do then is have the containing page reset all of the properties to the state they were in at whatever iteration rendered your component. You could do that by triggering an event from your component which instructs the container to set all the bound parameters based on some context from the originating event. Have a look at: http://tapestry.apache.org/5.3/apidocs/org/apache/tapestry5/ComponentResourcesCommon.html#triggerEvent(java.lang.String, java.lang.Object[], org.apache.tapestry5.ComponentEventCallback) Josh On Tue, Jan 3, 2012 at 7:16 PM, Bo Gao wrote: >>> I have changed all the values I want to persist to context values and it >>> works for me now.> Is this the only way to solve this problem? >> >> Probably not, but it seems like a fine solution. > > Is there some other solutions?

Re: Why Components in Loop are the only one instance? What should I do?
I have a zone in my component. And an event link to refresh the zone. So I need to use a persists value to store the zone's client id, and I persist some value that will show inside the zone. I have changed all the values I want to persist to context values and it works for me now. Is this the only way to solve this problem?

Re: Why Components in Loop are the only one instance? What should I do?
This is by design. Tapestry pages/ components have static structure so no matter how many times you g through the loop you only get one instance of the component. What specifically are you trying to do? Maybe someone can offer some design tips.

Why Components in Loop are the only one instance? What should I do?
I put a Component in a Loop, and when I call System.out.println(this); I found that there are only one instance of the component. If I have some persist value in this Components they can't work well. Why this happened? What should I do if I want to put a Complex Component with persist value into a Loop?
