Custom component issue

Custom component issue
According to customer requirements, we want to get such an effect in the development of custom components:
Drag and drop custom components to the Flex builder work area, it can generate more than the default properties, not just generate "x", "y" attribute.
【Details are as follows】
We design a custom panel "CustomPanel.mxml" in the project development, then drag it into the workspace in the Flex builder development environment.
View the source code found that it can only generate "x", "y" attribute in default. That is:
<ns2:CustomPanel x="105" y="74">
</ns2:CustomPanel>
【Issue】
How can we do that when drag the 'custom component' into Flex builder workspace, we can generate "layout" attribute in addition to "x", "y" attributes?
That is:
<ns2:CustomPanel x="105" y="74" layout="absolute">
</ns2:CustomPanel>
【Note】
The following code will be generated when the "panel component comes with Flex builder environment" is dragged into workspace.
<mx:Panel x="121" y="134" width="250" height="200" layout="absolute">
</mx:Panel>
How it is done?

I am sorry to bother you again.
I have tried the web site content, but it can't helped!
There is a custom component called 'Basket', source code is as follows:
package picnic
import mx.containers.Panel;
public class Basket extends Panel
public function Basket()
   super();
   layout = "vertical";
   setStyle("backgroundColor", 0x00FFFF);
   setStyle("horizontalAlign", "center");
Here it is worked when the attribute "layout" is set to "vertical", but it isn't when "layout" is set to "absolute" !
When the property is set to "absolute" phenomenon is as follows:
Drag component such as 'Button' into "picnic component". It will automatically go to the top left corner position,
just like the 'layout-attribute' is not set.
Why is there such a phenomenon?

Jsf custom component issue

I am creating a custom component and extending the renderer like the following. My custon component is similar to h:messages but inaddition to that it has hyperlink(clicking error focuses individual input box). I have extended the renderer as follows, every thing works fine but the problem is the form gets null or looses its all value when error occured, however the component works fine. I dont know why is that hapening.
Any help would be highly appreciated.
public class CustomErrorRenderer extends Renderer {
@Override
public void encodeEnd(FacesContext context,
UIComponent component) throws IOException {
ResponseWriter writer = context.getResponseWriter();
writer.startElement("div", component);
writer.writeAttribute("id", component.getClientId(context), "id");
writer.writeAttribute("style", "color: red", null);
writer.startElement("ul", null);
Iterator<String> clientIds = context.getClientIdsWithMessages();
while (clientIds.hasNext()) {
String clientId = clientIds.next();
Iterator<FacesMessage> messages = context.getMessages(clientId);
if (!messages.hasNext()) { continue; }
String javaScript = "var field = document.getElementById('"
+clientId+ "');" +"if(field == null) return false;"+
"field.focus(); return false;";
writer.startElement("li", null);
writer.startElement("a", null);
writer.writeAttribute("onclick", javaScript, null);
writer.writeAttribute("href", "#", null);
while (messages.hasNext()) {
writer.writeText(messages.next().getSummary(), null);
writer.endElement("a");
writer.endElement("li");
writer.endElement("ul");
writer.endElement("div");
}

The problem is, the form values that are tied to input boxes are null once validation error occurs.
I think when I am overriding that encodeEnd, this is causing the problem for the form values getting null.
IF I want to see, what are the submitted values then isn't this the way, I am getting null here also:
          FacesContext context = FacesContext.getCurrentInstance();
              UIViewRoot viewRoot= context.getViewRoot();
             HtmlInputText input = (HtmlInputText)viewRoot.findComponent("formId:InputboxId");
          System.out.println("input sub value" + input.getSubmittedValue());

Did you update the export layout too and added that to preferences?

Creating a custom component is causing a strange scoping issue

I am a fairly new user to Flash and Actionscript, but I have
a fair amount of experience working with C and Java. I'm currently
working with Actionscript 2 in Macromedia Studio 8. I was trying to
create a new component for a project I am working on, and I
followed the tutorial in the help and all testing works while I am
in context of the flash document where I export the component from.
However, I try testing my component in a new blank document and I
get some strange behavior.
I am able to create a component on the stage, and adjust the
properties perfectly fine. However, when I test the file, the
variables for colors go out of scope. That is, the adjustments I
made to the component through the parameters panel, and saw updated
on the stage aren't demonstrated at runtime. The Number variable I
used however is preserved. I did some traces, and it appears that
this is happening because at runtime in the new blank document, the
variables in the onEnterFrame method go out of scope, where they
weren't before.
It seems really strange to me that I should be able to edit
the color on stage but have it revert while it is running. My
intuition says that if it wasn't going to work in the new document,
that it shouldn't work in either case.
Anyway, here is the code for the .as file, I hope I'm just
doing something stupid.

There seems to be a little confusion here. Think of it this way:
A basic UIComponent by itself is not visible; you can add something you can see to it to make a visual custom component. For example, a ComboBox component is a UIComponent with a ComboBox added to it.
The UIComponent is the lightest weight component available from which you can create other components. I use it as the base for custom components that the user cannot see, like a data manager.

Unable to Edit the View in Custom Component

Hi Experts,
Please help me to resolve this issue !
I am unable to lock the BOL Entity in my custom component using BTAdminH. I have written the below code in the Edit event Handler for Edit Button. The lr_entity->lock( ) condition statement is getting false and it is skipping the "set_view_editable( me )." code statement. Why??
This is code excerpt that I have taken from edit button of the BP_HEAD/AccountViewSet and altered to my component/View
DATA: lr_entity     TYPE REF TO cl_crm_bol_entity,
        lr_controller TYPE REF TO cl_ZVKH8_bspwdcomponent_impl.
TRY.
      lr_controller ?= me->comp_controller.
      lr_entity ?= lr_controller->typed_context->btadminh->collection_wrapper->get_current( ).
IF lr_entity IS BOUND.
IF lr_entity->IS_LOCKED EQ abap_false.
    IF le_entity->IS_CHANGEABLE EQ abap_true.
       IF lr_entity->lock( ) EQ abap_true.
        me->view_group_context->set_view_editable( me ).
       ENDIF.
    ENDIF.
ENDIF.
ENDIF.
and when I directly executed the below code in the Edit event Handler for Edit Button I am receiving the dereferencing NULL value exception. Why in my custom component in many places this happening??
me->view_group_context->set_view_editable( me ).
Exception Details
CX_SY_REF_IS_INITIAL - Dereferencing of the NULL reference
Method: ZL_ZVKH8_DETAILSEF_IMPL=>EH_ONBACK
Thanks,
Bujji

Hi Summit & NishaNC,
Thanks for your responses !
As suggested, I have debugged the code for ->lock( ) method and there are exceptions raised from some methods.
Method GET_LOCK () -> Method GET_ROOT () ->Method GET_PARENT ()
At GET_ROOT( ) method i have received an exception
"Root entity BTAdminH could not be determined" and one more "Entity BTAdminH could not be locked"
Later when I have checked in MODEL Browser, I found that the BOL object "BTAdminH" for my view is an Access object and not the Root Object.
Hence, I have a question? Does the locking can be done only for ROOT Objects?
If this is TRUE then I think this is the major problem with my custom component where even the cross component navigation is also not happening and in many places I am receiving "Dereferencing NULL Value" information.
Also I have gone through some of the Threads and one information that I found from Sumit Mittal
1. An access object is an independent entity, has primary keys of its own.
2. A root object is a special access object that is at the top of the hierarchy based on business rules.
3. A dependent object's primary keys are supplied by access objects and it's lifetime is bound to them. If the parent object is destroyed, the dependent object is also destroyed.
4. Search objects are query objects useful for querying root objects
5. Search result objects - Search objects return the results in the form of a result object together with a relation pointing to the root object.
6. View objects - ?
7. Dynamic search objects - Used in advanced search, supports ranges and operators
Could you please specify in which scenarios we have to go for Access Objects and Root Objects
Thanks,
Bujji

Using itemCreationPolicy with a custom component

I'm working on a project where the users need to be able to have a 'filtered' view of one of the edit dialogs. I'm using view states to control which of the input fields show up for each view. The 'save' logic is the same for both states, so I still need to be able to pull data for the inputs even if they are not currently displayed. I tried setting itemCreationPolicy to immediate with no success. Some of the inputs were getting created but the initial values were not being set. The issue seems to be that the input component (an extended version of DropDownList) defers setting the selected value until the commitProperties() method. Since the inpit isn't actually being shown, the commitProperties() method is never getting called and the value is never being set.
Can anyone suggest a workaround for this issue? The only thing I can think of would be to use includeInLayout and visible to show/hide the inputs, but that is going to get really messy since I would have to apply it to every input and the FormItem components that enclose them.

Jasmin,
Is your class included in the custom component?
Yes, It is a annotated entity class,
When creating sessionFactory it is not loading the class.
i'm using flowing code block for creating sessionFactory,
factory =
new AnnotationConfiguration().addAnnotatedClass(dao.entity.UserEntity.
class).setProperty(
"hibernate.dialect",m_dialect ).setProperty(
"hibernate.connection.driver_class", m_driverClass).setProperty(
"hibernate.connection.url", m_connectionUrl ).setProperty(
"hibernate.connection.username",m_userName).setProperty(
"hibernate.connection.password", m_password).setProperty(
"hibernate.hbm2ddl.auto", m_hbmTodll ).setProperty(
"current_session_context_class",m_contextClass ).configure(resource).buildSessionFactory();
Is the jar referenced in the class patch section of the component.xml?
Yes , I have tried for this approch too , but class is entity class is not loaded.

How a custom component is called when we install a custom component in UCM.

How a custom component is called when we install a custom component in UCM.
On what event the component services will be activated and called.
Suppose i create a Custom service name MULTIPLECHECKIN then this service will be called on what event and where it will be defined to call.

Saurabh,
the code is packed in the component (see component\Security Filter\java\Security Filter\ModifyAttributesFilter.java - the first Security Filter is the component name, the other Security Filter is the Java package name).
What is important:
- your class must implement the FilterImplementor interface (you will need UCM standard classes - server.zip in your classpath) and its doFilter method
How the filter is executed?
- actually, in this case you don't need any new service - you can use the standard 'hook', which is provided by standard checkin services
- in Component Wizard create a new component, add your compiled class to it (make sure you follow the rules not to end up in classpath issues)
- in Component Wizard click the 'Java Code' tab. Here you can add a Custom filter called validateCheckinData, which is executed by standard checkin services. If you parametrize the filter to call your class created above, you are done.
'Working with Content Components' manual (e.g. here: http://download.oracle.com/docs/cd/E10316_01/cs/cs_doc_10/documentation/developer/using_components_10en.pdf) can give you a basic picture. A better resource is Bex Huff's book - I would recommend you to get it, because it has a step-by-step HelloWorld example which can guide you through Component Wizard. I could also send you my own component (send me an email at [email protected]) which implements a filter for user quotas, so you just need to "replace classes".
As for the other half of your task, searching for the file in the database server will work only if you use database as your storage (ie. install and configure File Store Provider component accordingly). Of course, you could do a search for file in this case - just consider that you will be comparing two BLOBs rather than two relatively short check-sums (most likely strings or arrays of bytes). Besides, it will not work if you use filesystem as your storage.

Scroll bar, buttons and a Custom Component - help

Thanks to another forum I was able to create a scroll panel and add a scroll bar to it. That works fine. Inside the scroll panel I have thumbnails of the product that I'm highlighting. I want to be able to click on the thumbnail and have a full size photo of the product come up in the window next to the scroll panel. I created a custom component that has a stage showing each full size product individually. This worked fine when I simply had buttons and no scroll bar. I could convert the thumbnail to a button and then add interaction so that it would go to the proper state of the custom component. Where I'm having problems is now that I've imbedded the buttons in a scroll panel I'm no longer given the custom component as an option to pick from. I can add interaction, but it only gives me the option of picking one of the pages, and not a component.
I've attached a screen grab to help show what I'm describing.
Any ideas?
Doug

Doug, thanks for asking this question.
Hi ADAM...
It seems that a lot of us are asking the same question: Scrollbar Navigation-Make Actionable
(I created a low-fidelity proof-of-concept to test—using a datalist as you suggested. See link in my posting).
I have reviewed the video you refer to here, but you example still does not allow for individual items in the datalist (scrollbar) to be assigned individual actionable events.
Can you expain your thinking in Option 1, as a workaround? Do you have any other suggestions?
BOTTOM LINE
We are all looking to do the same thing... something we are going to see A LOT MORE of after Uncle Steve's TABLET presentation next week:
A scrolling menu, with selected items in the menu causing "navigation" to a certain point in a scroll panel. (imitating the flick or slide effect of iPhone).
Suggestion: Can you add a field to thedatalist so that when the "repeated item" (in edit mode) is configuredto do an action (i.e., On-Click, Transition to State), we can then assign the state you'd like for each item in thetable itself?
Now the issue is making it change the "State" within another component (i.e. scrolling panel). Can that be done?
Thanks,
- Rick

Custom component not found by jsf (mojarra)

Coming from this link http://forums.sun.com/thread.jspa?threadID=5446475&tstart=0
I have managed to get things together but for some reason, my app is not able to find the custom component at runtime. I have the component configured in my web.xml so that is not it. I am not sure if this has something to do with the fact that I am not able to see any JSF 2.0 annotations during runtime. I actually using spring for my component scan due some issues I had earlier on with JSF. At that time I was told that because I am using maven tomcat plugin for development, I might not be able to get that working. The explanation was that maven tomcat plugin uses tomcat 6.012 that does not support something, I cannot remember that makes JSF behave properly. Some advised me to use jetty but I have had a chance to try that. Has someone faced this kind of issues before? If so please let me know I am running out of time for this project. Thanks a million in advance.

Thanks a million in advance.What do you mean you have the component configured in web.xml? While I can't say what effect Spring has on things as I don't use Spring, all you need are the annotations on the component, the entries in the -taglib.xml if you're using facelets, and an "empty" (root-element only) faces-config.xml set to version 2.0 in the jar if the component is jarred (as opposed to being part of the .war).
When you say JSF can't find your component, are you getting an error message? Does the tag just appear in the browser unprocessed?
Testing on GlassFish would be helpful (for me) as there are no known issues there in this area.

FXML loading custom component scene slow

All we are creating a custom component to place into a TilePane each time a user clicks a button like so
FXMLLoader loader = new FXMLLoader(resource.getURL());
Pane panel = (Pane)loader.load();
Scene scene = panel.getScene();
When we get panel.getScene() it is empty. So we created a new scene and then added that node to the tilePane. The only issue is, it is very slow and takes forever to appear on the tilePane. Is this the correct way of doing it?

Why do you need a new Scene? Surely the TilePane is already shown in a scene; you can just do
tilePane.getChildren().add(panel);
Maybe I am misunderstanding the question though.

Change base view state from a custom component

I'm pretty new to flex and I'm having a small issue in change the view state from a component.
My Application have 2 custom components called userlogin and main menu. In the main application page I have userlogin component in one state and the main menu component in another. I'm trying to change the state if the login in successful from user login to main menu. I have the following function written inside the login component.
private function IsUserLoggedIn(evt:ResultEvent):void
                if (evt.result.islogin.toString() == "true")
                    currentState = "MainMenu";
                else
                    Alert.show("Login failed, please try again.", "Login Failed");
This code worked when I had all the controls in the main page. But then I created components and included them in to components and now when the login is success, its giving the following error.
ArgumentError: Undefined state 'MainMenu'.
    at mx.core::UIComponent/getState()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\core\UI Component.as:9908]

    at components::UserLoginForm/__btnSubmit_click()[C:\Projects\WarrantyAutomation\src\componen ts\UserLoginForm.mxml:60]
I'm sure this has something to do with accessing the states from a custom component, but I do not know how to change the state to the main menu. Please help me with this. Any help is greatly appriciated.

Hi dasun1981,
private function IsUserLoggedIn(evt:ResultEvent):void
                if (evt.result.islogin.toString() == "true")
                    currentState = "MainMenu";
                else
                    Alert.show("Login failed, please try again.", "Login Failed");
If I am right the above function is in your userlogin component and the two components "userlogincomponent" and "maincomponent" are in main application file and the states were also defined in main application file.
But in the function above the currentState refers to the state of the userlogin component and not the main application ...but the states are defined in main application file...that's the reason why the exception was thrown...
Instead you replace the line in the above function with the below line:
Application.application.currentState = "MainMenu";
Please mark it as answer if it helped you.

LCES server caches the custom component classes

I found that sometime during the (patching) deploy/undeploy install/uninstall phase of custom component LCES start 'caching the custom component or its helper classes' and any changes made to them does not get reflected.
But after the server restarted every thing work as expected.
i.e. If server is restarted the latest changes to component deployed previously to server restart get reflected.
Pl. help.
Any one had simillar issue?
Thanks
Yog

Hi Paul,
I have tried both of these frequently (many times)
1) Component > STOP > PATCH > START
2) Component > STOP > UNINSTALL > INSTALL > START
but no effect after some point when server keeps the cache. (it works some time but not all the time I thought 2nd approach should always work)
But if I restart the server it seems to show the expected result always.
Does any Adobe teche knows how to gaurrentee 100% that chnges will reflect after new version of the component is installed without restart of the server.
Also I seen some inside the service impl at the begining of the service method code store the classloader:
ClassLoader originalClassloader = Thread.currentThread().getContextClassLoader();
and restore it at the end of service method:
if (originalClassloader != null) {
Thread.currentThread().setContextClassLoader(originalClassloader);
How does this affect?
and also if one component depends on another how does that affect?
Thanks

Button in custom component not showing

I made a very simple custom component with a TextField and Button but when I add multiple instances of it to a Layout, only the first Button shows up while the other show only when I focus the corresponding TextField. I'm quite new to fx and I'm not sure I did everything correctly but I don't see any obvious error in my code.
The component:
public class TestComponent extends BorderPane {
    @FXML
    private Button browseButton;
    @FXML
    private TextField textField;
    public TestComponent() {
        FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("TestComponent.fxml"));
        fxmlLoader.setRoot(this);
        fxmlLoader.setController(this);
        try {
            fxmlLoader.load();
        } catch (IOException exception) {
            throw new RuntimeException(exception);
The fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.HBox?>
<fx:root type="javafx.scene.layout.BorderPane" xmlns:fx="http://javafx.com/fxml/1"
    xmlns="http://javafx.com/javafx/2.2">
    <center>
        <TextField fx:id="textField" prefWidth="200.0" />
    </center>
    <right>
        <Button fx:id="browseButton" mnemonicParsing="false" maxHeight="-Infinity"
            minHeight="-Infinity" prefHeight="${textField.height}" text="Browse"
            textAlignment="CENTER" />
    </right>
</fx:root>
and the test code
@Override
    public void start(Stage primaryStage) {
        VBox box = new VBox(5);
        box.setPadding(new Insets(5));
        TestComponent a = new TestComponent();
        TestComponent b = new TestComponent();
        TestComponent c = new TestComponent();
        box.getChildren().addAll(a, b, c);
        Scene scene = new Scene(box);
        primaryStage.setScene(scene);
        primaryStage.show();
I'm running on Ubuntu with jdk-8-ea-bin-b111-linux-i586-10_oct_2013. I tested with jdk 1.7.0_40 and the buttons don't show.
I'd include screenshots but the button to add images is disabled.
Thanks for the help

The issue is with the bind definition in the FXML, if you remove that definition, the buttons will display.
   prefHeight="${textField.height}"
I think the binding is working, but when there is some kind of error (bug) in the layout process such that the scene is not automatically laid out correctly when the binding occurs.
You can get exactly the same behaviour by removing the binding definition in FXML and placing it in code after the load.
            browseButton.prefHeightProperty().bind(textField.heightProperty());
When the scene is initially displayed, the height of all of the text fields is 0, as they have not been laid out yet, and the browser button prefHeight gets set to 0 through the binding.
That's OK and expected.
Then the scene is shown and a layout pass occurs, which sets the height of the text fields to 26 and the prefHeight of all of the browser buttons adjust correctly.
That's also OK and expected.
Next the height of one of the buttons is adjusted via a layout pass.
That's also OK and expected.
But the height of the other buttons is not adjusted to match their preferred height (probably because a layout pass is not run on them).
That is not OK and not expected (and I think a bug).
If you manually trigger a layout pass on one of the components which did not render completely, the button will be displayed - but that should not be necessary.

PropertyNotFoundException on a custom component

Hello,
I'm experiencing some issue while using a custom component in a FXML file. I try to instanciate my comp and tu set a text with the command :
<fx:include source="MyComponent.fxml" text="myText" />
I have linked my component to a controller using fx:controller="myPackage.MyComponent" and in this MyComponent.java I wrote a setter :
+public void setText(String text){ ... }+
Yet, during the execution, I always get a PropertyNotFoundException : Property "text" does not exist or is read-only.
I guess I forgot a little something but I don't managed to find what. Could somebody help me with this issue please ?
Léo

The "text" property in this example applies to the root element of the included file, not its controller:
<fx:include source="MyComponent.fxml" text="myText" />So, in order to process this markup, you'll need to make sure that the class represented by the root element defines a setText() method.
