Hi All,

Can any1 here help me with this, let me explain the problem. I have been trying to create a dynamic drop down in JSF Web Beans the first drop down list(chapter) managed to populate the 2nd drop (district), however the 2nd drop down list did not get to populate the 3rd drop down list which is "han". Before this I am using the JSF's ViewScoped which works but I am now trying to migrate to the CDI way of doing it....it don't work.... anyone.. please help

<f:view><h:form> <h:selectOneMenu id="chapter" value="#{testDynamicDropDown.selectedUser}" valueChangeListener="#{testDynamicDropDown.prepareDistrictsList}"> <f:selectItems value="#{testDynamicDropDown.users}" /> <f:ajax event="change" render="district"/> </h:selectOneMenu><br /><br /> <h:selectOneMenu id="district" value="#{testDynamicDropDown.selectedUser}" valueChangeListener="#{testDynamicDropDown.prepareHansList}"> <f:selectItems value="#{testDynamicDropDown.users2}" /> <f:ajax event="change" render="han"/> </h:selectOneMenu><br /><br /> <h:selectOneMenu id="han" value="#{testDynamicDropDown.selectedUser}"> <f:selectItems value="#{testDynamicDropDown.users3}" /> </h:selectOneMenu> <br/> </h:form><br /></f:view> </h:body>


@Named("testDynamicDropDown") @ConversationScoped public class TestDynamicDropDown implements Serializable { @Inject Conversation conversation; private ArrayList<String> users; private ArrayList<String> users2; private ArrayList<String> users3; private String selectedUser; public String getSelectedUser() { return selectedUser; } public void setSelectedUser(String selectedUser) { this.selectedUser = selectedUser; } @PostConstruct public void create (){ users = new ArrayList <String> (); users.add("John"); users.add("Charley"); users.add("Priscila"); users.add("Kate"); users.add("Emily"); users.add("Barack"); users.add("Mia"); users.add("Arthur"); System.out.println("in post construct"); // conversation.begin(); } public void prepareDistrictsList(ValueChangeEvent event) { conversation.begin(); Object obj = event.getNewValue(); String selectedChap = (String)obj; if(selectedChap!=null){ users2 = new ArrayList <String> (); users2.add("John"); users2.add("Charley"); users2.add("Priscila"); users2.add("Kate"); users2.add("Emily"); users2.add("Barack"); users2.add("Mia"); users2.add("Arthur"); } } public void prepareHansList(ValueChangeEvent event) { // conversation.begin(); Object obj = event.getNewValue(); String selectedChap = (String)obj; if(selectedChap!=null){ users3 = new ArrayList <String> (); users3.add("John"); users3.add("Charley"); users3.add("Priscila"); users3.add("Kate"); users3.add("Emily"); users3.add("Barack"); users3.add("Mia"); users3.add("Arthur"); } } public ArrayList<String> getUsers() { return users; } public ArrayList<String> getUsers2() { return users2; } public ArrayList<String> getUsers3() { return users3; }

the snippet that you post only works in session scope isnt it ?
will it work in request scope ? I try to get it to work with t:saveState yet it does not work.

Hi,

I am a newbie in java, forgive me if its a simple question

currently I want to display an internal frame in an MDIFrame that I made

THe problem is that the commands to invoke the internal frame isnt from the MDIFrame class, and its not working when I try to do so

for example

I have class A
public class A implements ListSelectionListener{ void projects_mouseClicked(MouseEvent e) { if(e.getClickCount() == 2){ System.out.println("Double clicked occured"); MDIFrame callingForProjFrame = new MDIFrame("hi"); callingForProjFrame.callProjectFrame() } }
the corresponding MDIFrame class

public class MDIFrame extends JFrame { void callProjectFrame(){ ProjectFrame showProFrame = new ProjectFrame(); this.jdp.setLayout(null); showProFrame.setLocation(100, 110); showProFrame.setSize(500, 500); showProFrame.setVisible(true); this.jdp.add(showProFrame); showProFrame.show(); System.out.println("Here are you"); }

Above are the snippets of the code,
can any1 please please tell me wat is wrong ?

I cant get the internal frame showed in the jdesktoppane... if I call the method as such, whereelse when I call it directly from the MDIFrame class it displays the internal frame, which then again....

I unable to do so, because of the situation that I am having here..

PS:

thanks

Hi,
I am beginner user in JBuilder,

I am just curious of the way of doing it

If I have a Frame with contentPane all those inside liau if I wan to draw a panel but I dun wan draw it inside tat class meaning I draw it in another class extending Panel how can I add tat external class, the extended Panel that I have done to the frame.

Meaning, can I like select that class and drop it in to the frame and it will be added automatically

is that any solution other then hardcoding them manually

ops
mayb I get myself wrong,

wat I mean is like the JButtons in JToolbar

when we click on the button in toolbar something like a dropdown menu will appear

something that we often c in Borland JBuilder and MsWord

For eg: when we click the icon New

there will be another list of drop down menu listed

Hi,
I have a newbie question here, I would like to know how do we attach a drop down menu to a button in the JToolbar ?

I could not figure out how it works for days thank you
