Dynamically disabling component

I'm very new to JSF and have got a question (I'm actually using a mixture of tag libs, but for this particular question, mainly jsf core and trinidad).
There are two items on a form, the first one is a single choice from a list like "alive, dead...".
What I want to do is that if it's "alive", then the next item, "death date", should be automatically disabled.
Is there a way for me to do this? Here is the code.
<tr:selectOneChoice id="status" value="bean.status">
<f:selectItems value="statusOptions" />
</tr:selectOneChoice>
<tr:inputDate value="deathDate">
<f:convertDateTime pattern="MM/dd/yyyy" />
</tr:inputDate>Any suggestions will be highly appreciated!

Were you talking about xml DOM?Uh no, HTML DOM. Open the JSF page using your favourite browser and view the source. All you see is just plain HTML/CSS/JS.
Does JS work with Trinidad?JSF just outputs HTML/CSS/JS to the client side and JS runs at the client side only. The client side doesn't care anything about the server side.

Foreground color of a disabled component

How do i change foreground/text color of a disabled component? Something similar to JTextComponent's setDisabledTextColor().

I'm not exactly sure but I think this is highly component dependent and even look & feel dependent. Sometimes, there isn't even a such color defined anywhere. The component's ui just takes the current foreground color and calls brighter on it.
You'll have to be more specific on the component you wish to modify.

JSF - Disable component messages

Is it possible to disable component's messages when using custom validators? I only want to display a list of messages on the top of the page, not the default behavior that displays the detail error message next to the component.
Can anyone help me? Thanks

Hi,
you could use the GlassPane for this:
JPanel glassPane = new JPanel();
glassPane.addMouseListener(new MouseAdapter() {
// select components on mouse events
glassPane.addMouseMotionListener(new MouseMotionAdapter() {
// drag or resize components on mouse events
frame.setGlassPane(glassPane);
glassPane.setVisible(true); // must be called after setGlassPane() !!Sven

Dynamic add component to panel, it does't work

I want to add a label in a panel when you click button.
I used revalidate() and revalidate() method, but it didn't appear in panel.
HELP ME?? WHAT'S WRONG!
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jPanel1.add(new JLabel("Hello"));
jPanel1.revalidate();
jPanel1.repaint();
}

i add Layout manager to panel. It works. Thanks,
So tricky things for dynamic adding component:
1, setup layout manager to container (such as panel),
2, add component to container
3, call revalidate() method to relayout these components in container
You can't miss any one of those.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jPanel1.setLayout(new FlowLayout());
jPanel1.add(new JButton("Hello"));
jPanel1.revalidate();
}

Skipping a disabled component in the tab order

It seems that when you disable a button, it isn't
automatically skipped in the tab ordering. Worse than that, the two
obvious methods of skipping a disabled component (in topic summary
above) have no effect. .... Is there a solution for this?

Dynamically add component question?

Hi:
Here is part of my code in short:
public class TextInputWithAutoComplete extends TextInput
private function addComp():void{
list = new List();
list.id = "autoCompleteList";
list.x = 0;
list.y = 20;
list.addEventListener(MouseEvent.MOUSE_UP, handleMouseDown);
parentDocument.addChild(autoCompleteList); OR addChild(autoCompleteList); //my question is here
private function handleMouseDown():void{
//TODO
I realized that if I do addChild, I can't really see the dynamically added component, since flex did not reserve space for my List to display. So I do parentDocument.addChild, and then the component appears no problem. My question is since it's being added in the parentDocument, so it is suppose to be a component belong to parentDocument, so is that component still be able to call this handleMouseDown?
From my experience, it's still able to, but which doesn't make sense to me.
Can someone explain a little about why it can still work, or any better approach other than parentDocument.addChild
Thanks.

In Flex there is a lifecycle that represents the contract between the component and its parent. See the chapters on creating custom components and the lifecycle methods createChildren, commitProperties, measure and updateDisplayList.
Some components size to content like Containers. When you add a child to a container it will measure the child and make room for it or add scrollbars if there isn't enough room.
If you add a child to TextInput, it doesn't expect additional children so it will not make room for it. You can subclass and override its measure and updateDisplayList methods to make room for an additional child.
I would not recommend adding another interactive control to an interactive control since that will make managing focus and accessibility much harder. It is better to group these in a container in most cases.
The reason the mouse handler still gets called is because a handler can be on any object whether it is a child or sibling or parent and will be called by the object dispatching the event if the handler is listening to that object. If you had attached the handler to "this" it would not get called when the List is not a child of "this".

Dynamic declarative component won't work properly within table row

Hi guys,
I built a dynamic declarative component which basically consists of an af:inputText surrounded by a af:panelLabelAndMessage tag.
The component works fine until I put it inside a table column, then none of the attribute values get set.
The problem seems to be related to the table row binding #{row.binding.Name.inputValue} , if I use a regular binding #{binding.Name.inputValue} it works ok.
The declarative components attribute is defined as
<attribute>
    <attribute-name>kbez</attribute-name>
    <attribute-class>java.lang.Object</attribute-class>
</attribute>and is used as the inputText's value attribute
<af:componentDef var="attrs" componentVar="component">
    <af:panelLabelAndMessage label="#{attrs.label}" id="dc_plam1"
                             for="dc_it1" labelStyle="white-space:nowrap;"
                             showRequired="#{attrs.showRequired}"
                             rendered="#{attrs.rendered}">
        <af:inputText id="dc_it1" value="#{attrs.kbez}"
                      autoSubmit="true" immediate="false" ...>The component inside a table column is set like this
<af:declarativeComponent viewId="/WEB-INF/ikb.adf.kreda.basis/mitarbeitersuche/ddc/mitarbeiterLOV.jsff"
                         id="ddc1" label="Mitarbeiter"
                         kbez="#{row.bindings.Kbez.inputValue}"/>My JDeveloper version is 11.1.1.5.
Am I doing it wrong or is this a bug?
Any help is appreciated.
Thank you,
Achim

Hi,
+#{row.binding.Name.inputValue} , if I use a regular binding #{binding.Name.inputValue} it works ok.+
Don't think that #{binding.Name.inputValue} works okay in a table because it doesn't stamp the component per row. Actually I don't know if we support dynamic declarative components in a stamped environment (table). I know though that we don't for taglib declarative components in this context.
Reason why it doesn't work: Tables are stamped at runtime, which means that for better performance, only the generated HTML is reused for each row with different data - not the component. Your component requires itself to be re-created for each row so it can re-read the attribute again. This is not the case in a stameped environment
Solution: For your particular use case I don't think that a dynamic declarative component is needed as you can add the construct (af:inputText surrounded by a af:panelLabelAndMessage) directly into an af:column tag. The declarative component makes more sense for reuse of layout areas (e.g. custom tabs) that are iterated within an af:forEach (in which case instances of the decalarative components would be created).
Bottom line: tables stamp their components and as such the attribute property exposed on a DDC doesn't seem to be called for each row, which is by design. This can be considered a bug if there is a use case demanding for a DDC in a table. If this is a requirement for you (and you can't directly add the components to the af:column tag) feel free to file this as a service request with customer support (required a support contract) so development can have a look if the requirement is feasible to implement.

Dynamic Declare Component cannot find property

We currently have one main page calls a DDC(Dynamic declarative component) page fragment to create/update a record in database. The main page pass in a key to DDC when it loads DDC. The DDC binds to a view object with bind variable (get value from the passed key and load data from table) and several LOV attributes. Once user clicks submit button in main page, we wish that all the fields displayed in DDC could be committed to a database table to save.
I use 11.1.1.5.
In order to assign the bind variable of VO, we wrote a method in Application Module and make it invoked as the first executable when the main page is loaded. The deployment is fine. However, the runtime always thrown some exception to complain it cannot find property definition like this:

Hi,
I appreciate if you can show your code, but before that, make sure if you're following this tip below:
"Declarative Components are regular JSF components except that they are built as a composite out of existing ADF Faces components. Declarative components cannot have a PageDef file associated with it and instead use value or method attribute to communicate with the consuming page. When creating a declarative component, the attrs implicit object is defined that allow you to reference the component's exposed value attribute from ADF Faces components within.
An input text field contained in an declarative component may reference a value attribute "compValue" defined on the declarative component by using the following EL
#{attrs.compValue}
The declarative component compValue attribute then would us an EL reference like shown next to read/write values from or to the ADF binding layer:
#{bindings.attribute_name.inputValue}"
(Oracle ADF Code Corner)

Dynamic Form componants in my jsf page?

how could i make dynamic form componant in my jsf page ,depend on user inputs or result from database or whatever , where i use sun studio creator ???

you need to use the "rendered" attribute of the components...
for example in your jsp put this...
<h:outputText value="Hello" rendered="#{myBean.renderHello}"/>
the render hello method looks like this in your backing bean "myBean"
public boolean getRenderHello() {
return true; // or false
if getRenderHello() returns true, "Hello" will be displayed, if getRenderHello() returns false, it will not...
you can also use expressions in the jsf... for example...
<h:outputText value="Hello" rendered="#{myBean.someNumber == 5}"/>
if the "getSomeNumber()" method in your backing bean returns 5 it will be true and "Hello" will show up... otherwise it won't... :)
Hope this helps...

Dynamic create Component usage and embed it in view container

There is a view_container_uielement VC_TEST in view V_MAIN, in wd component ZTEST.
I created a web dynpro component named ZWDR_TEST and add it into the wd component ZTEST.
    gr_comp_test = component->create_cmp_usage_group(
      name = 'TEST_GROUP'
      used_component = 'ZWDR_TEST' ).
    lr_comp_usage = me->gr_comp_test->add_component_usage(
      embedding_position = 'V_MAIN/VC_TEST'
      name = 'TEST'
      used_component = 'ZWDR_TEST' ).
    if lr_comp_usage->has_active_component( ) is initial.
      lr_comp_usage->create_component( component_name = 'ZWDR_TEST' ).
    endif.
    ifc_test ?= lr_comp_usage->get_interface_controller( ).
I thought the wdr ZWDR_TEST was embeded in the view V_MAIN in the position VC_TEST by the embedding_position parameter.
But in the result web page, there is no ZWDR_TEST in the position of VC_TEST.
Could any one explain why?
Thanks

How to get the Dynamic UI component value from JSFF page to any managedbean

HI ,
We have list of bean objects in jSF page we are iterating the list of bean using the forEach loop and displaying the value into Input type text (UI component) value filed .
If we try to get the UI component value in Managed bean we are not getting the dynamic values .
The below piece of code used to retrieve the dynamic values from the JSF page doesn't have any form :
UIComponent component = null;
FacesContext facesContext = FacesContext.getCurrentInstance();
if (facesContext != null) {
UIComponent root = facesContext.getViewRoot();
component = findComponent(root, componentId);
then component type casting to the based on UI component which we trying to access and getting the value as " NULL " ..Please let me know how to get the dynamic values form the JSF ?
Please let me know if any other approach or any changes required on above ?
Thanks

Hi,
the root problem is this
<h:inputText id="it3" value="#{familyList.ctn}" />
<tr:commandButton text="Save" id="cb3"Note how each row writes to the same managed bean property, thus showing the same data. Instead your managed bean should expose a HashMap property that you then apply values to using a key/value pair. The key could be the ID of the field, which then you also should dynamically define e.g. cb<rowIndx>. The command button could then have a f:attribute assigned that has the row HahMap key as a value. This way you truly create value instances for the object

Embedded Fonts on Dynamic Label Component

I am working on a project that calls for multiple label
components to be dynamically rendered based on a selected comboBox
selectedItem. The comboBox is a choice of fonts available to the
user - all of which are embedded fonts. For some reason, the fonts
are not embedding correctly for systems that do not have the font
on the system.
I have added the fonts to the library and selected "Export to
ActionScript" as well as "Export in First Frame" (although I want
to preload these later once this issue is resolved). In my steps to
simplify and solve, I created a basic movie with a label on the
stage with an instance name of "label0".
In my Actions frame, I use the following code:
label0.text = "This is a font test";
label0.setStyle("fontFamily", "Vivaldi");
label0.setStyle("fontSize", "40");
label0.setStyle("embedFonts", "true");
I have seen examples on the web where someone uses
label0.embedFonts = true; but that doesn't seem to work either. I
have also tried various fonts to verify the font will embed.
Thinking I may not be embedding it correctly, I checked the
bandwidth profiler and variables list and the size goes up after I
try to embed the font as well as the label0 variables correctly
show embedFonts = true as well as the fontFamily is set to Vivaldi
(sample).
Many people have used Dynamic Text Fields but I need to use a
Label so I can use the autoSize feature as users are allowed to
choose their own font size (between 10pt and 40pt). The label
component seems to be the right option for me with the exception of
the font selection. To be safe, I added a dynamic text field and
embedded the fonts there as well and hid it off stage. When viewing
it on another system, the dynamic text field worked (poorly) but it
showed the font. The label did not show the correct font.
Any help would be greatly appreciated.
Thanks

Yes, when I set label0.setStyle("fontSize", "40"); the size
changes for both systems (the one that has the font installed as
well as the one that doesn't). On the system that doesn't have the
font, it appears as a Times New Roman font in large type.

How to create dynamic tree component

I am using netbeans 5.5 and visual web pack to develop my jsf application.
I want to add a tree component that will be tied to a table with following columns:
id,parent_id,name
Actually the table stores data in tree structure with parent_id storing the parent of the row.
So a row with parent_id = 0 will be the root nodes of the tree.
When ever any root node is selected i want to fetch its children from the database and populate then as children of that parent node.
The tree can go to any depth so i want to make my tree component dynamic enough to handle this requirement.
How can i accomplish this.
I just want to add listerner for the plus sign of every node so that when the plus sign of that node is clicked i just want to get the id of the corresponding node.

What i'm trying to do is create an organizational structure.
Global>Region>Plant-->Corporation
The output from the RFC is a structure containing every possible combination for orgazational hierarchy. Basically a flat table with record for every possible combinaton of Region-Plant-Corporation. This data needs to be bound to a tree structure so that we can call BW queries based on that level. For example: Give me aged inventory for the SAP corporation within the plant Berlin that is located in the Europe region.
Now that you understand the business reason will the nodes that represent Region and Plant and corporation be non-singleton nodes or recursive? I was thinking a hierarchy of non-singleton nodes.
I can bind these nodes to the Region - Plant - Corporation elements returned from in the flat table structure. I will probably get duplicates as a specific Region will be listed multiple times for every possible combination of the data beneath it. I'm not so concerned about that right now as I want to make sure I understand how in Web Dynpro to bind the data to the tree.
Hopefully this makes some sense. Can you elaborate on how this may be constructed in context of the view?
Would i create a model node for region (0..n), model node for plant (0..n), and a model node for Corporation (0..n)?
Or does this sound totally incorrect?
julian
We have 3 regions over 50 plants and probably around 500 corporations.

How to make content of af:popup dynamic? Component Value is not updating.

HI,
     I am not able to update the component used in af:popup dynamically.
     In my case, the value of the component used in the popup is updated every time before opening the popup.
     I am building the af:popup. I am using component binding for my components. And I am setting data in the component using the component in the Managed bean only. The getter method for every component that I bind gets called only once i.e. while loading of the page. So when ever I change any thing in the component in managed bean, it is not reflecting in JSPX page. Coz it not calling the getter method of the component, so it is not getting the updated status for the component. But if you refresh the page you will get the updated component.
     Following is the sample code to simulate my problem,
     JSPX Page:-
<af:commandButton text="RCF Dialog (Without Script)" id="button1"
windowHeight="600" windowWidth="600">
<af:showPopupBehavior popupId="samplePopup" alignId="button1"
align="afterEnd"/>
</af:commandButton>
<af:popup id="samplePopup" clientComponent="false"
contentDelivery="lazyUncached">
<af:dialog title="Sample Dialog Test" modal="true"
cancelVisible="true" okVisible="true">
<af:inputText label="Label 1" value="#{searchField.myValue}"/>
<af:inputText label="Label 2" binding="#{searchField.textField}" />
</af:dialog>
</af:popup>
Managed Bean:-
public static int count = 1;
private String myValue = null;
private CoreInputText textField = new CoreInputText();
public String getMyValue(){
String value = "MESSAGE_" + count;
System.out.println("Count ==>" count " Value ==>"+value);
count++;
return value;
public CoreInputText getTextField() {
//Get called only once at the page load.
textField.setValue(getMyValue()+"_XXX");
return textField;
public void setTextField(CoreInputText textField) {
//Get called every time dialog is opened.
this.textField = textField;
Please let me know what to do make the content of the af:popup dynamic.
Any suggestions are welcome.
