Dear Wiki user, You have subscribed to a wiki page or wiki category on "Jakarta-tapestry Wiki" for change notification.
The following page has been changed by HenriDupre: http://wiki.apache.org/jakarta-tapestry/PopupLinkSubmit New page: == PopupLinkSubmit == This is a solution for submitting a form and at the same time open a popup with an external link. It is a little lousy since it requires alot of copy paste from Tapestry code. I hope this can look better with future Tapestry versions. === Example=== {{{ <a href="#" jwcid="@PopupLinkSubmit" parameters="ognl:article" listener="listener:acheterArticle" popuppage="PopupPanier" popupparameters="ognl:article.AR_Design">Acheter</a> }}} {{{ package actualis.web.tapestry.components; import java.util.HashMap; import java.util.Map; import org.apache.hivemind.ApplicationRuntimeException; import org.apache.hivemind.service.BodyBuilder; import org.apache.tapestry.IComponent; import org.apache.tapestry.IForm; import org.apache.tapestry.IMarkupWriter; import org.apache.tapestry.IRequestCycle; import org.apache.tapestry.IScript; import org.apache.tapestry.PageRenderSupport; import org.apache.tapestry.TapestryUtils; import org.apache.tapestry.annotations.InjectObject; import org.apache.tapestry.engine.ExternalServiceParameter; import org.apache.tapestry.engine.IEngineService; import org.apache.tapestry.engine.ILink; import org.apache.tapestry.form.FormConstants; import org.apache.tapestry.link.DirectLink; import actualis.web.tapestry.components.form.FormMessages; /** * Implements a component that submits its enclosing form via a JavaScript link.
