Karthik.Nar,
I made the change below to Result.java. It seems to work, but is this
optimal? Is there a way for the component to automatically find out it's
"parent page" to bind the value without using a "double" bucket brigade
and/or without using component injection. I'm new to Tapestry still, so
might not understand even what i'm talking about!
Is this the best practice? Thank you for your advice.
Result.java
-------------------
package uk.co.gd.dao;
import org.apache.tapestry.annotations.InjectComponent;
import org.apache.tapestry.event.PageBeginRenderListener;
import org.apache.tapestry.event.PageEvent;
import org.apache.tapestry.html.BasePage;
public abstract class Result extends BasePage implements
PageBeginRenderListener {
@InjectComponent("searchComponent")
public abstract SearchComponent getSearchComponent();
public abstract void setSearchText(String searchText);
public abstract String getSearchText();
public void pageBeginRender(PageEvent event) {
if (event.getRequestCycle().isRewinding()) {
System.out.println("in pagebeginrender but rewinding");
return;
}
System.out.println("in pagebeginrender not rewinding");
((SearchComponent)
getSearchComponent()).setSearchText(getSearchText());
}
}
