h:commandButton

Hi,
I am new to JSF.
Can any one tell me how to disable a button based on some condition,for example I have a field with status="A" on the jsp page then the button should be disabled with status="A" and it should be enabled with status="U".
any help is highly appreciated.

<commandButton disabled="#{bean.status == disabledValue}">.

Using commandLinks and commandButtons in dataTables

I'm trying to create a page that displays data from a database and allows you to edit individual rows by clicking on either a commandButton or a commandLink within a dataTable that then takes you to another page where you can edit that particular row of the table.
When using a commandButton, it works perfectly for all but the last entry in the table. But when the button in the last line is clicked, nothing happens at all, it does not seem to call the action listener and it does not perform the navigation based on the action. But with all the previous buttons it calls the actionListener and navigates perfectly. Can anyone tell me why this would be? The code is as follows:
<h:dataTable value="#{Categories.categories}" var="category" >
<h:column>
<f:facet name="header"><h:outputText value="#{msgs.deptColumnHead}"/></f:facet>
<h:outputText value="#{category.departmentName}"/>
</h:column>
<h:column>
<f:facet name="header"><h:outputText value="#{msgs.categoriesColumnHead}"/></f:facet>
<h:outputText value="#{category.categoriesList}"/>
</h:column>
<h:column>
<h:form>
<h:inputHidden id="dept" value="#{category.departmentId}"/>
<h:commandButton id="editButton" action="EditCat" actionListener="#{Categories.editListener}" value="{msgs.editSelectedButtonText}"/>
</h:form>
</h:column>
</h:dataTable>
When using commandLinks, only the first one works (of 4). For the other 3 the page goes into error when the link is clicked and it complains that 'document.forms._id2:3:_id10._id2:3:_id10:idcl is null or not an object'. If anyone could tell me what is wrong with my code, i would be most appreciative.
<h:dataTable value="#{Categories.categories}" var="category" >
<h:column>
<f:facet name="header"><h:outputText value="#{msgs.deptColumnHead}"/></f:facet>
<h:outputText value="#{category.departmentName}"/>
</h:column>
<h:column>
<f:facet name="header"><h:outputText value="#{msgs.categoriesColumnHead}"/></f:facet>
<h:outputText value="#{category.categoriesList}"/>
</h:column>

<h:inputHidden id="dept" value="#{category.departmentId}"/>

1) I have had very odd behavior in JSF when ALL of the
JSF elements on a page do not have an id attribute. If
you do not assign an id then JSF will manufacture a
unique id on the flag. Sometimes the unique id wasn't
so unique and there were errors like you are seeing or
just odd behavior on the form, buttons not generating
events, or incorrect rendering, etc.
By 'ALL' I mean output text, columns, anything that
accepts an id attribute. Don't trust the code to
generate an id correctly for you.Just want it known that while this may be necessary in the short-term to work around bugs, this is definitely not the intent of the EG! We don't want people getting in the habit of
Also note that this behavior is not consistent
sometimes it would not appear on a page unless the
page was updated and more controls added to it.Ah, well that is a known issue; while developing a page, the Sun RI can have problems if you change a page's contents between two submissions. (It doesn't pick up that the .jsp has changed.) I'd recommend:
- Use client-side state saving.
- Make sure you're making a new request for a page (not re-POST-ing anything!) when the page's contents have changed.
If you follow both of those rules, then you should generally be able to get away without explicit IDs everywhere as you actively develop your page.
Explicit IDs are required if you're inside <c:if>; this is known and documented.
2) try putting the hidden input control in it's own
columnNo, that'll give you a bonus set of <td> elements, which isn't what you want.

CommandLinks and CommandButtons in Datatable do not work

I have read the threads about this issue and am aware of the fact that there is a problem, if the backing bean is in request scope. However, my backing bean is in session scope and it still does not work - my action methods are never called. What's more, I have another backing bean in session scope, where it works perfectly and I cannot see any difference between them.
Here's the code, my backing bean is dms:
<h:form rendered="#{dms.documents.rowCount > 0}">
<h:dataTable rowClasses="..." headerClass="..." value="#{dms.documents}"
columnClasses="..." var="item" border="1" cellpadding="2" cellspacing="0">
<h:column>
<f:facet name="header">
<h:outputText>DocName</h:outputText>
</f:facet>
<h:commandLink action="#{dms.test}" value="#{item.docName}"/>
</h:column>
<h:column>
<f:facet name="header"/>
<h:commandButton id="foo" value="View" action="#{dms.test}"/>
</h:column>
</h:dataTable>
<h:commandLink action="#{dms.test}" value="Clickme"/>
</h:form>
Here is the code in the backing bean:
public String test() {
System.out.println("Hooray");
return "mainPage";
And this in faces-config.xml:
<managed-bean>
<managed-bean-name>dms</managed-bean-name>
<managed-bean-class>com.mypackage.DmsController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
Only the last link, the one outside the datatable and titled "Clickme", works. I can see "Hooray" in the logfile and am redirected to the main page. If I click any of the links or buttons in the datatable, nothing is written to the log and the same page is loaded again, but only the static content is displayed, i.e. no JSF tags are evaluated, they are just dropped. There are, however, a few hidden input fields called javax.faces.ViewState, which I don't know where they are coming from.
As I said, I have another backing bean in session scope, which is modelled exactly like that and it works there. Maybe JSF apps are supposed to have only one controller?
Many thanks in advance for any pointers,
Ulrich
Edit: It doesn't change anything if I put the backing bean in application scope. I did have the same problem before with my other backing bean, but could solve it there by putting it from request scope to session scope.

<h:dataTable value="#{dms.documents}">How do you load this list? This list should not be null during the INVOKE_APPLICATION phase.
Try stubbing the List right in the getDocuments() method and see if it works.

ADF 10.1.3.3 Blocking attribute commandbutton does not work

I can set the blocking="true" for my commandbutton in my jspx and it works fine on my local and on a dev server. (working as expected with the hourglass). In a different dev environment (the one we use to preview to our users) when the user clicks on the commandbutton the arrow turns to the hourglass very quickly then back to the arrow. The same EAR is deployed on both of the dev environments yet they are behaving differently. Any suggestions?

Hi,
when the hourglass is set back, is the processing done ? Maybe the machine is faster than the others

Having a problem with commandButton attribute when i am using it under tabl

Having a problem with {color:#800000}commandButton {color}{color:#339966}attribute {color}when i am using it under{color:#ff0000} table{color}
I am using a command button under a table.
here is the example
<h:dataTable value="#{wlmHandler.plexes.plexes}" var="{color:#ff0000}onePlex{color}" border="0" cellspacing="0" cellpadding="0" width="100%" border="0">
<h:column>
<h:panelGrid border="0" cellpadding="0" cellspacing="0" columns="5">
<h:commandButton action="" styleClass="tixbutton" value="#{labels.ADD}" onclick="#{onePlex.tran}"/>
<f:verbatim> </f:verbatim>
<h:commandButton action="#{createTransaction.transactionCommand}" styleClass="tixbutton"
value="#{labels.SUBMIT}" actionListener="#{createTransaction.processAction}">
<f:attribute name="dbName" value="#{wlmHandler.dbName}"/>
<f:attribute name="plexName" value="{color:#ff9900}#{onePlex.name}"{color}/>
</h:commandButton>
</h:panelGrid>
<h:/column>
</h:dataTable >
when i am using this plex name atribute it is giving nullPointerException
{color:#ff9900}this value #{onePlex.name} i cant able to access inside the command button{color}

balu i have tried by seeing u r blog.
this is my structure of tables
plexes (if i iterate plexes table gives plex object)
|
------ plex (plex table gives transaction object)
|
------transactions(transactions table gives transaction table)
|
here i will have a command link to this link i have to pass the plex name which
will come from
i tried in this command action with HTMLDataTable getRowData()
i am not getting the selected row data .i am downcasting this getRowData() to plex.

Problem with commandLink and commandButton

I am tired of this ...
I am using tiles for displaying jsf pages . Any problem because of using tiles

If I open the url directly its working fine
let say I am opening localhost:8080/test/test.jsf
then it works fine
If i use the same test.jsf along with tiles and open it, then its dispalying all the elements but when i click on commandbutton.. nothin is happening.
the seems like page is reloaded.

Problem with commandButton in a custom DataTable

I am trying to write a cutom DataTable and am having some trouble. I don't think that the DataTable that gets shipped has the flexibility that we need for our pages. That's why I'm trying to write my own.
What I have is a commandButton in one of the column headers for the table. It is bound to a method in a backing bean. The page seems to render correctly. But when I click on the button, it seems to make a trip to the server, but the method doesn't get invoked.
I figure that I'm missing something in my custom component, but I just can't figure it out. Does anyone have any ideas?
If you would like for me to post some/all of the code just let me know. I didn't what might be helpful.
Thanks,
Ray

Thank you for your response.
I already had a messages tag on my page and no messages come out. I've looked in the log and don't see anything in their either. I put in a phaseListener and all of the phases are being processed.
Here is my output. It is the same whether I press the button that is inside my custom dataTable or press a button that is outside my custom dataTable.
beforePhase RESTORE_VIEW 1
afterPhase RESTORE_VIEW 1
beforePhase APPLY_REQUEST_VALUES 2
afterPhase APPLY_REQUEST_VALUES 2

beforePhase UPDATE_MODEL_VALUES 4
afterPhase UPDATE_MODEL_VALUES 4
beforePhase INVOKE_APPLICATION 5
afterPhase INVOKE_APPLICATION 5
beforePhase RENDER_RESPONSE 6
afterPhase RENDER_RESPONSE 6
The problem is, when I press the button that is inside my custom dataTable the method for the button doesn't get invoked. So I believe that I have something wrong in my custom dataTable that isn't building the component tree correctly. Does anyone have any ideas for this?
Here is the class that renders my col tag. That tag puts out the <th> that the button is in.

How to get af:commandbutton id in java code when it is triggered?

Hi All
In my application's homepage, I am using 2 af:commandbuttons and each using action attribute to call a method. Both are calling the same method, and based on its id, it should perform different operations. Could anyone please tell me how to get command buttons id in java code, when it is triggered.
Regards
Venkat

Venkat,
why not call different methods from each button?
public String actionButton1()
return doAction("button1");
public String actionButton2()
return doAction("button2");
public String doAction(String aBuuton)
if ("button1".equalsIgnoreCase(aButton))
// do work for button 1
return "abc";
}else {
// do work for button 2
return "abc";
}Now you user actionbutton1 for the first button and actionButton2 for the second.
Or you directly implement two different methods in the bean and call each one directly from the button.

How to close popup with af:commandButton without submitting values?

Hi all,
I'm using JDeveloper 11.1.2.1
My popup has few af:inputText components with value attribute binded to view scope variables.
I set those view scope variables in backing bean before showing popup.
When I change values of input fields and click cancel (af:commandButton, partialSubmit=true, immediate=true), popup is closed.
Then, when I show popup again, values that I changed are visible although I set new values to view scope variables in backing bean before showing popup again.
I noticed that when I close popup using close icon in upper right corner of popup everything works fine.
Also, I tried using dialog cancel button and it also works fine.
Is there a way for closing popup using af:commandButton but without submitting values?
In previous releases of JDeveloper (<= 11.1.1.5) I didn't noticed this problem.
Thanks in advance,
Aleksandar

See the documentation of af:popup for that. Canceling a popup is a pure client-side operation. No event is sent to the server. No submit. No need to reset anything. That's basically what the built-in cancel button does as well.

CommandButton doesn't invode the function in backing bean.

I have a jsp page which contains three buttons, and based on a session level state, only one shown at the beginning. Once this button is clicked, the other two are shown and the first one is hidden.
When the first button (add) is clicked, the other two are shown correctly. But when I clicked any one of them, none of their backing bean methods are called. I checked the log, no exception.
Then I tried to show all buttons at begining, and click them. Both backing bean methods are invoked.
Did I miss something in the life cycle of JSF?
Here is the part of jsp page:
<h:commandButton action="#{manageBranches.doAddBranches}" image="/images/add.gif" rendered="#{!manageBranches.isAdd}"
styleClass="toolbaricon" title="#{messages['branches.dropdown.add.branches']}"
onmouseover="swapImage( this, 'add.gif', 'add_down.gif' );"
onmouseout="swapImage( this, 'add.gif', 'add_down.gif' );" />
<h:commandButton action="#{manageBranches.doEditBranches}" image="/images/edit_icon.gif" rendered="#{manageBranches.isAdd}"
styleClass="toolbaricon" title="#{messages['branches.dropdown.edit.branches']}"
onmouseover="swapImage( this, 'edit_icon.gif', 'edit_icon_down.gif' );"
onmouseout="swapImage( this, 'edit_icon.gif', 'edit_icon_down.gif' );" immediate="true" />
<h:commandButton action="#{manageBranches.doSaveBranches}" image="/images/save.gif" rendered="#{manageBranches.isAdd}"
styleClass="toolbaricon" title="#{messages['branches.dropdown.save.branches']}"
onmouseover="swapImage( this, 'save.gif', 'save_down.gif' );"
onmouseout="swapImage( this, 'save.gif', 'save_down.gif' );" />
Here are corresponding backing bean methods:
     public String doAddBranches()
          Logger.logEnterPublic(MY_CLASS, "doAddBranches()");
          setIsAdd(true);
          return null;
     public String doSaveBranches()
          Logger.logEnterPublic(MY_CLASS, "doSaveBranches()");
          String forward = null;
          if(addedBranchIds ==null || addedBranchIds.length()==0)
MessageFactory.addErrorMessage( null, "branches.selectAtLeastOneBranch", null );
this.successMsg = false;
return forward;
          else
               String[] branchIdArray = addedBranchIds.split(":");
          this.successMsg = true;
          //TODO: add save logic
          return forward;
     public String doEditBranches()
          Logger.logEnterPublic(MY_CLASS, "doEditBranches()");
          String forward = null;
          setIsAdd(false);
          return forward;
The add button worked fine. But when save and edit button were shown and add button was hidden. Both save and edit button can't access the backing bean methonds. I put a break point on the constructor of the backing bean, it WAS accessed!
Very confusing!
Thanks for any helps.

Ok, I'm not 100% on this, but it's something you can try. In your action methods, you often return null when you want the page to just be reloaded. I believe in JSF, returning null and returning a string that represents the same page is quite different. I think this is because the component tree will get re-initialized when you return a proper string. It's quite possible that you need to have the component tree re-initialized for everything to work properly.
Therefore, whenever you want to reload "pageA" then return an abbreviation called "A" (or whatever you want). In your faces-config.xml set up a rule that when outcome "A" is received (while on pageA) then load pageA.jsp.
Hope that makes some sense! Let me know if it works.

How can I publish my Visio project to PDF including active CommandButtons (VBA)

Hi everyone,
First of all, I am new on this forum and a rookie when it comes to Visio and creating PDFs, that's why I need some help. The Visio project where I am working on, is part of my assignment. I am hoping that you could help me.
I am creating an interactive system for employees with Microsoft Office Visio 2007 that shows flowcharts of procedures and work instructions. Now I created multiple pages and I added hyperlinks (to switch to different levels) and simple CommandButtons (Microsoft Forms 2.0 CommandButton) that show UserForms, which I created in Visual Basic Editor. When I click the CommandButton in the project (on Fullscreen) the UserForm appears.
For the CommandButtons I added this code:
Private Sub CommandButton3_Click()
UserForm4.Show
End Sub
This document I created needs to be a controlled document and it should be published in PDF. I know that Visio already has a plugin to publish PDFs, but when I use this option, my project (in PDF) does not show active CommandButtons (where I can click on in order to open my UserForm). Though, the hyperlinks I created, DO work. Do I need to change the VBA code for my CommandButtons or my UserForms, so that I can open my UserForms in the PDF- file? If the answer is 'yes,' does anyone know the code I need to add?
I also would like to know how I can make my Shape ScreenTips visible in PDF? Do I need to add 'User defined cells' in order to do that or do I need to change something in the Miscellaneous section?
Many thanks!
PS: I have enclosed a picture how it should work. You can see one page with a opened UserForm on the lower right. This result (or something similar) I would like to see in the PDF- file.

You cant transfer interactivity to a PDF when you print to PDF as you have written.
PDFs have to be exported so that interactivity will live inside the PDF. Of course you have to set up links in the Hyperlink Panels.
But not every reader is supporting interactivity. URL are supported from Reader and Apple iBooks. But you can't force the user to use a certain application anyway.

How to use one commandButton to execute two tasks in JSF

I have a form in JSF page which contains different faces components. These faces bind to ADF BC to insert one row in the database when the user press commandButton. Also I need to bind the value of one inputText in that form to managed bean to execute another task in the application when the user press the same commandButton.
The code of the inputText:
<h:inputText value="#{bindings.ProjectNumber.inputValue}"
id="pn"
size="10"
required="#{bindings.ProjectNumber.mandatory}">
The code of commandButton:
<h:commandButton actionListener="#{bindings.Commit.execute}"
value="Save"
disabled="#{bindings.Commit.actionEnabled}"/>
The managed bean is �findInspector�. I tried to insert inputHidden inside commandButton tag and assign the value of the inputText to the inputHidden as follows:
<h:commandButton actionListener="#{bindings.Commit.execute}"
value="Save"
disabled="#{bindings.Commit.actionEnabled}">
<h:inputHidden value="#{bindings.ProjectNumber.inputValue}" binding="#{findInspector.project}"/>
</h:commandButton>
But it was not work
Please how can I write the code to use the value of the inputText more than one time in the JSF(one to insert one row by using ADF BC and another to use the same value to bind to a managed bean) and how to use one commandButton to execute two tasks in JSF.
Thank you
Waheed

Just dopublic void execute() {
anotherAction(inputValue);
I guess those articles might be interesting about passing params and the usage of inputHidden and also about using datatables:

Yes I did
<managed-bean>
<description>The bean for get project No</description>
<managed-bean-name>projectBean</managed-bean-name>
<managed-bean-class>
mcscm.model.ProjectBean
</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>bindings</property-name>
<value>#{bindings}</value>
</managed-property>
</managed-bean>
Also I changed the method in the managed bean as follows:
public String commandButton_action() {
FacesContext fctx = FacesContext.getCurrentInstance();
ValueBinding vb = fctx.getApplication().createValueBinding("#{bindings}");
DCBindingContainer dcb = (DCBindingContainer) vb.getValue(fctx);
OperationBinding operation = (OperationBinding) dcb.get("projectNumber");
operation.execute();
return null;
where projectNumber is my method in the java class of the application module "TaskInformationImpl". I made this method to be accessed from outside of ADF BC.
I just create a sample code for projectNumber method for testing only as:
public void projectNumber (String data){
System.out.print(data);
In the page Pagedef file I added this :
<methodAction id="projectNumber"
InstanceName="TaskInformationDataControl.dataProvider"
DataControl="TaskInformationDataControl"
MethodName="projectNumber" RequiresUpdateModel="true"
Action="999" IsViewObjectMethod="false">
<NamedData NDName="data" NDValue = "#{bindings.ProjectNumber.inputValue}" NDType="java.lang.String"/>
After I did all of this I get a new error like:
javax.faces.FacesException: #{projectBean.commandButton_action}: javax.faces.el.EvaluationException: java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlAttrsBinding cannot be cast to oracle.adf.model.OperationBinding
Is it very difficult to do this in JDeveloper?. yes ADF BC provide me a lot of facilities, but when I want to do a specific task I face a lot of troubles

How can i call a bean methos using h:commandlink or h:commandButton?

Hi
i want to call a methos in the bean class throught h:commandbutton action
my code is
<h:commandLink action="#{sample.tryStuff1}" immediate="true" rendered="true">
<h:outputText value="add" />
</h:commandLink>
<h:commandButton id="ad"
action="#{sample.tryStuff1}"
immediate="true"
value="add"
type="SUBMIT"/>
what does immediat do here
i am trying both ways but its not calling the methosd.
what am i doing wrong?
my config file
<managed-bean>
<description>sample</description>
<managed-bean-name>sample</managed-bean-name>
<managed-bean-class>com.actsys.web.sample</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
please help
thansk in advance

have you tried the following?
<h:commandLink value="add" action="#{sample.tryStuff1}" />Also, it might be good to know if you are actually getting to the action method tryStruff1, what does sys.out show if you have it in the first line of the action method?
If you are getting to the action method, then there is probably an issue with your navigation handler.

Action / actionListener in h:commandButton with managed beans

I have a problem with a backing bean whose method is not invoked when i click it. I've seen some posts on here about this yet, I still don't understand what I am doing wrong, if anything.

http://www.javaworld.com/javaworld/jw-07-2004/jw-0719-jsf.html . It's simpler than the article -- I'm not using Spring/Hibernate and the persistence is the file system. For each business object (Resource), there's a backing bean (ResourceBean).
In short, I can't get the backing bean to respond to the button event for 'Add' bound to addAction. This is just like the jcatalog 'createProduct' impl -- which doesn't use the (FacesEvent fe ) approach.
Anyway, I would appreciate anyone's help to get past this.

(Note, the applicationBean uses view services manager. The manager is used by the ResourceBean. (It's initialized by the h:output dummy variable reference at the top of my .jsp page)). I can see the initialization in the debug trace.

Hey, anyway, have you note your jsp reference to the backing bean begins with a lowercase letter, and your backing bean class name begins with an uppercase letter?? I think that's it... I think, cause I'm too unexperienced in JSF.... Bye!!

CommandButton and commandLink behaving differently for file download

Hello there,
Hopefully someone can help - I have looked through the existing queries and can't just find what I'm after.
I have a main record with asociated files - the files are uploaded through my web app and are downloaded from the same page that lists the files in a dataTable. I have a series of commandLinks that display the file names - a user selects the file and it downloads.
The problem I have is that when a user downloads a file then immediately trys to upload another, they are prompted to download the file that they have already previously downloaded. If however I replace the commandLinks for commandButtons the application behaves correctly.
I have seen an associated link that mentions similar behaviour (http://blogs.sun.com/tor/entry/creating_downloadable_files), however I do not want to use the command buttons in this manner, and I use an actionListener rather than an action so I may retrieve information from the list of dynamically created files. I am not receiving any errors, just the strange behaviour with commandLinks.
My code is as follows:
public void downloadFile(ActionEvent ev) {
UIData fileList = findParentHtmlDataTable(ev.getComponent());
AssociatedFile associatedFile = (AssociatedFile) fileList.getRowData();
String downloadPath = "download path retrieved here...";
try {
byte[] fileData = InternalUtil.readFile(downloadPath);
HttpServletResponse response =
(HttpServletResponse) getFacesContext().getExternalContext().getResponse();
response.setHeader("Content-disposition", "attachment; filename=\"" +
associatedFile.getName() +
response.setContentLength(fileData.length);
response.setContentType(associatedFile.getContentType());
ServletOutputStream out = response.getOutputStream();
out.write(fileData);
getFacesContext().getApplication().getStateManager().saveSerializedView(getFacesContext());
getFacesContext().responseComplete();
} catch (FileSystemException e) {
getFacesContext().addMessage("null", new FacesMessage("Error downloading file: " +
e.getMessage()));
} catch (IOException e) {
getFacesContext().addMessage("null", new FacesMessage("Error downloading file: " +
e.getMessage()));
Any help would be greatly appreciated!
Thanks in anticipation, Carl
