Hello again --
I have a WORepetition in a table set up, listing off dates and
headlines for a news archive. I would like to have each headline be a
hyperlink to reload the current page with the related news item
content. The way I figure it is that I would need to make each
WOString headline be contained in a WOHyperlink. This would then be
bound to an action that sets a key, and returns null. But I have yet
to get into the WebObjects mindset, and don't know how to get the
newsId key from the WORepetition and into the next page.
I always do this sort of thing with component actions. So you have an
array newsList and an iterator variable called newsItem. You put a
WOHyperlink where you want it and bind the action to the following
action:
public WOComponent gotoNewsItem() {
WOComponent nextPage = pageWithName("newsItemPage")l
nextPage.takeValueForKey(newsItem, "newsItem");
return nextPage;
}
This assumes that there's a public getter/setter or ivar on the next
page to receive the value for newsItem.
