ZK Desktop Cleanup not called when accessing from an Ipad

March 27, 2015, 10:12 am

The basic problem is my desktop cleanup listener is not being called when the application is accessed from an ipad, but it is called when accessed from a PC browser (ubuntu, windows, mac - doesn't matter) I have defined a desktop listener in zk.xml : Called when the ZK Desktop is detroyedcom.dh.ui.common.desktop.DHzDesktopCleanup in Java : public class DHzDesktopCleanup implements DesktopCleanup {.... @Override public void cleanup(Desktop desktop) throws Exception {.... } This is called as it should be when I access my application from a desktop browser. However, when I access it from the Ipad (from within our webapp or using safari) the cleanup is never called. I am monitoring desktops using the following code on a page to keep track of sessions and desktops. I also have set a breakpoint in the cleanup method to check when it's being called. Statistic statistic = (Statistic)Executions.getCurrent().getDesktop().getWebApp().getConfiguration().getMonitor(); _activeDesktops.setValue(new Integer(statistic.getActiveDesktopCount()).toString()); _activeSessions.setValue(new Integer(statistic.getActiveSessionCount()).toString()); _totalDesktops.setValue(new Integer(statistic.getTotalDesktopCount()).toString()); _totalSessions.setValue(new Integer(statistic.getTotalSessionCount()).toString()); If I only access the application from the desktop the active count will go up and down correctly with the number of connections. When I access from the Ipad, the count only goes up, never goes down even when I kill the connecting app or safari. Is this a bug or is something else going on? Thanks! Andy

It seem like zk combobox doesn't support grouping like http://harvesthq.github.io/chosen/ or listbox, grid, so I must custom this component. That's right?

ZK forum upvote system need change

1. This forum has upvote system where we can upvote someones answer to a question if we feel it is worthy of it, but there is a limit that you need to have some minimum points to do upvote, even if you are the one who has asked the question you are not allowed to upvote a answer or to accept someone's answer 2. If you have asked a question and now want to close it, the closing process is also ambiguous or may i am missing something and not able to find the "close the question" button anywhere. I should be allowed to accept or reject any answers to at least the questions which i have asked, I did asked some questions and someone did try to help me with answering them, but i have no way to tell them that i am glad to receive there helping hand. 3. karma system makes sense but the only problem is the rules of how your karma increases or decreases or even the points system rules are not clearly mentioned anywhere. PS- I might be wrong and all this info might be available somewhere hidden in some link on this site but again it should be something that should be accessible more easily to a new bee like me on this site. updated :- http ://forum.zkoss.org/faq/#gravatar Found a link where they explain the point system, but again to get points or Karma you have to have some karma in your bank or you have to depend on "Karma" guys who have it with them, what if someone gives a really good answer to some new bee's question, does't he deserve to get some upvote or points for that.

Determine the binding (the bean backing a textbox) of a component in a HtmlMacroComponent

Hello everyone, i created a Macro-component: With a custom Java-Class, extending HtmlMacroComponent: @ComponentAnnotation("value:@ZKBIND(ACCESS=both,SAVE_EVENT=onEdited)") public class MyMacro extends HtmlMacroComponent { private static final long serialVersionUID = 1L; @Wire private Textbox textbox; @Wire private Popup popup; private Label label; public MyMacro() { label = new Label(); setMacroURI("/zul/components/myMacro.zul"); setStyle("display:block"); afterCompose(); popup.appendChild(label); } @Listen("onFocus=#textbox") public void textboxFocus() { label.setValue("some Text"); popup.open(textbox, "end_before"); } public void setValue(String value) { textbox.setValue(value); } public String getValue() { return textbox.getValue(); } @Listen("onChange=#textbox") public void textboxChange() { Events.postEvent("onEdited", this, textbox.getValue()); } } In this HtmlMacroComponent i would like to determine the Binding, that is forwarded in the place the macro is used: By this i mean the name of the bean and the field and not the content. It could be the class of the bean or the getter of the vm or anything else really, that helps me to unequivocally identify the bean and field. To make it more clear, i'm searching for a method like: textbox.getBinding() // Returns "field.bean" or [org.package.Bean.class, "field"] or something like that Can someone help me with that?

Hello, I'm trying to add a timeline in my project but I have a little problem . when I did it with a static data ( xml file ) there's no problem because in the data file we can define the trackNum for every event we'll create. but in my case, I have a dynamic data that I get from a server, so I have to create a model and add occurEvent to it but I cannot define the trackNum when creating occurEvent from java code. OccuEvent does not have a trackNum property. do you have any idea about how to set trackNum for added Events ? Thanks in advance!

Monitoring with New Relic

Hello. I have an application built on ZK 5 and I'm trying to implement the Real User Monitor funcionality in New Relic to monitor application usage and performance. The user interface is implemented with Java clases instead of zul files so I'm looking for the best way to implement this. In the New Relic site there are samples for JSPs, Servlets, ColdFusion, Velocity ... nut they have nothing currently implemented for ZK. They say that for RUM a pair of JavaScripts should be included in the header and footer sections in some specific places, but I've not found a way to do this in for example a Window object. So if there is anybody who could give me some pointers or can share some tips, it would be greatly appreciated. Best regards.

With this I have a way to **share zul files** and their controller classes between web apps withou having the need to copy (I hope so, but did not finally check yet). **BUT, what about sharing the language resources (like "i3-labels") or images, CSS, js?** Any idea?
