Disable - command button

We use jdeveloper 11.1.1.3
In a jspx page, I need to show a "save" commandbutton disabled to start with.
After the data is queried (inputtextfield1 gets shown) I need to show the "save" button enabled so that user can click.
That enabling is to be based on the inputtextfield1 value being not null.
How do I do this please.
Thanks for your help.

Here is the syntax:
<af:form id="f1">
<af:inputText label="Label 1" id="it1" binding="#{TestPageBean.myInputText}"/>
</af:form>
Bean Code:
import oracle.adf.view.rich.component.rich.input.RichInputText;
public class TestPageBean {
private RichInputText myInputText;
public TestPageBean() {
public void setMyInputText(RichInputText myInputText) {
this.myInputText = myInputText;
public RichInputText getMyInputText() {
return myInputText;
*public boolean checkIfEmpty() {*
*if (this.myInputText != null) {*
*if (this.myInputText.getValue() == null) {*
return true;
return false;
I am NOT clear with your use-case. Can you please clearly specify?
Thanks,
Navaneeth

JDev 10 - disable command button depending on which row is selected

I am using JDeveloper 10, and I have a table which has some data columns and a selection facet with View and Edit command buttons.
I would like all rows to be viewable. When you click the view event it goes to another .jsp with the view action.
It does the same thing with the edit action, however I would like to only allow rows which have an EffectiveDate column in the future to be editable.
Is there some way to disable the edit button when those rows are selected, or to throw a validation error when the edit button is clicked for that row?
Thanks!
Jeff

                </af:tableSelectOne>
              </f:facet>
            </af:table>

So, I first tried using Chan advice, I added a new editable property from the database and then added Edit buttons to each row in the table with disabled property set to the editable property.
This correctly displayed buttons which were editable in the correct rows.
However, I was no longer using the select functionality which passed the rowId of the selected row to the edit page.
I wasn't able to quickly solve this problem so I tried John's solution.
I feel really dumb, but after about 20 rereadings it was still completely Greek to me, I have no idea what he was recommending.
So I added onclick="return editTest()" to the Edit button.
The I added ID to the relevant locations, and the following javascript to the page, and this is working well enough now.
(Oh, I display the date in a slightly odd dd-MMM-yyyy format, due to slightly odd customer requirements.)
I've probably misspelled one of the months, haven't yet finished testing.
A couple of gotchas I found
- Do not add onclick="editTest()" or else it will continue processing and allow all rows to be edited.
- Putting date = document.getElementById('mainFormId:tableId:'+i+':EffectiveDateId'); would work for the original search,
but after filtering results i and found_it are not equivalent, and date was not found in the page.
           function editTest(){
              var found_it;
              var date;
              for (var i=0; i < document.getElementsByName('mainFormId:tableId:selected').length; i++) {
                 if (document.getElementsByName('mainFormId:tableId:selected').checked) {
found_it = document.getElementsByName('mainFormId:tableId:selected')[i].value;
date = document.getElementById('mainFormId:tableId:'+found_it+':EffectiveDateId');
var result = date.innerHTML.split("-");
var day = result[0];
if (day.charAt(0) == '0'){
day = day.charAt(1);
var month;
var monthTxt = result[1];
switch (monthTxt) {
case 'Jan':

Command button remains disabled after a request redirect to a PDF Servlet

Hi All,
I've a command button to generate PDF on the fly and used to work in JDev 10.1.3.3.
When we migrated to 11g, it works for the first time on a page, and the file Open/Save dialog will come up.
But then the command button remains grayed out, and clicking doesn't generate a server call.
If I do something on the page which does a partial or full submit, then the button will get enabled again.
Any suggestions?
Thanks,
Jaimon
Sample code:
Facelets:
<af:commandButton text="Create PDF" action="#{fs02.createPDF}" />
Java:
public String createPDF() {
//Validation checks here. If there are any errors, it gets added to FacesMessages to display on the same page.
if(!validate()) {
//sf.addInfoMessage('message here..');
}else {
FacesContext ctx = FacesContext.getCurrentInstance();
HttpServletRequest request = (HttpServletRequest)ctx.getExternalContext().getRequest();
HttpServletResponse response = (HttpServletResponse)ctx.getExternalContext().getResponse();
RequestDispatcher rd = request.getRequestDispatcher("/pdfdownloader");
rd.forward(request, response);
ctx.responseComplete();
return null;
pdfdownloader is mapped as a servlet, which writes the actual PDF content as a stream.

Herewith the code which is triggered with the post-forms-commit trg. As far as I can see it, there is no code to disable/enable the save button in the menubar.

Set JSF Command Button Disabled

Hello,
I have a JSF command button, I would like to dynamically change button disabled based on certain condition.
I tried in the actionListener code in my managedbean
like
UIComponent component = event.getComponent();
component.setRendered(false);However it makes button not visible, couldn't find setDisabled.
How can I do this?
Regards

Hi,
Basically, you can change the button status: enabled/didasled from JavaScript by changing the button css.
You can also do this from JSF.
The commandButton element has the disabled attribute and you can change the status depending on your condition.
-- <h:commanButton disabled=""
Please find an example: http://www.roseindia.net/jsf/EnableDisableButton.shtml
If you use AJAX (ex. a4j) there is the same principle. In backing bean you can check your condition and in jsp you'll change to disabled.
Hope this helps,
Sergiu

How can I control the enable/disable of command buttons in ADF JSF

I have been having a great deal of trouble trying to work out how to control the command button such that if the rowset is null then the button is disabled. The trick is that the rowset is not defined by the view where the command button is located. The rowset is defined by a view which has a "view" command button which displays the specific row selected, then this view has a command button that will display the detail rowset of the selected master row, but if there are no detail records I want the button to be disabled. How can I do this in ADF JSF? If I use a backing bean to make the determination prior to the page rendering then how does the backing mean method set the parameter necessary to disable the command button? Any advice or tutorial that I can use is most appreciated. My goal with using ADF JSF effort was to demonstrate that a complex app could be generated with minimum coding, I would like to keep to this concept if possible. Thanks,
Michael

Hi Michael,
You can probably set the Enabled property of the command button using an EL that would evaluate and return true or false based on your requirement.
Check out these links for more information on using the EL.

Cannot completely disable a dimmed command button

Hi! Everyone,
I thought this topic was solved before, but it comes back to me again.
Please take a look at the code in the attached project.
If the call of "Delay(5)" is placed after "ProcessSystemEvents()" call in the A_Callback() function, B-LED always light up no matter what!?
Dimming or making button B invisible doesn't disable the command button at all.
Only when I place the "Delay(5)" call in front of the "ProcessSystemEvents()", the B button will be disabled.
Just by dimming button B, without "ProcessDrawEvents()" and "ProcessSystemEvents()", won't guarantee the button is disabled.
I'm puzzled. What is the correct way of completely disable a command button?
Does this problem only happen in CVI 6.0?
Solved!
Go to Solution.
Attachments:
DimButtons.zip ‏5 KB

Whether or not you need to call ProcessSystemEvents to ignore clicks on a button depends on what you are doing at the time and when you will undim the control. The original question came up when the button was being dimmed and undimmed in a callback.
CVI defers processing of events while you are in a callback. If you're not currently in a callback, a click event will be processed when it occurs. If the control is dimmed when that click occurs, (again, outside of a callback), the event will be processed and ignored and you don't need ProcessSystemEvents.
Or if you dim the control from within a callback, then click on the control, then exit the callback without undimming the control, the event will be processed with the control dimmed and will therefore be ignored (without needing ProcessSystemEvents).
So the big question is when will you undim the control? If you undim it at the end of a long callback, then you need to call ProcessSystemEvents.
But if, for example, you open a panel with a control dimmed, and then undim it after some other event, you don't need ProcessSystemEvents to ignore the click.
Let's say you have a panel with a control for the user to select a filename, and a button to print the selected file. You don't want Print to be active until the file is selected, so it's dimmed initially by default. In a callback for the filename control, after the user selects a file, you can then undim the Print button without needing to call ProcessSystemEvents. Any click on the previously dimmed Print button will have already been ignored.

How to enable /disable a command Button based on a table's selectOne choice

Hi everyone.
I am using JDeveloper 10.1.3.3 and wish to enable / disable a commandButton based on the user's selection of the selectOne radio button.
The idea is that a row of a table may have an associated document so I want to enable or disable the button that downloads it based n the current row selected.
I have followed the advice on problem with table I defined my selectOne component as follows :
<af:tableSelectOne text="#{res['tables.selectionFacet.title']}"
    autoSubmit="true"
    attributeChangeListener="#{backing_browseCVs.onSelectionChange}">The function inside the backing bean looks like this
    public void onSelectionChange(AttributeChangeEvent attributeChangeEvent)
        // access the faces context
        FacesContext fc = FacesContext.getCurrentInstance();
        // get value of the expression #{row.hasCVDocument} that indicates
        // if a document has been added
        ValueBinding vb =
            fc.getApplication().createValueBinding("#{row.hasCVDocument}");
        Boolean hasDoc = (Boolean)vb.getValue(fc);
        // enable the doownload button accordingly
        downloadCVDocBtn.setDisabled(!hasDoc);
    }My problem is that the method never fires. I have placed a breakpoint at the first line but it is never reached.
Any advice will be most welcome.
Thanassis

Hi,
You might need to add 'dataProvider' part in the expression language in your selectionListener:
#{bindings.CVList.currentRow.[b]dataProvider.hasCVDocument}
#{bindings.CVList.currentRow} returns an instance of ViewRowImpl which does not have 'getHasCVDocument()' method, but does have:
Object getCurrentRow()
method, which returns objects from your CVList list, which do have getHasCVDocument() method...
Expression language is resolved through reflection, so when you write:
#{processScope.someClass.someReferencedClass.someAttribute} it is something like:
Get someClass from processScope map, then:
someClass.getSomeReferencedClass().getSomeAttribute()
It's a bit more complex but you get the idea.

Disable Command Link (Button)

From my backing Bean I would like to dynamically disable
the buttons on my jsp form. How do you do it? I have tried as I
would with fields but I get a failure.

There is no "disabled" attribute for commandLink. Perhaps it would be ok if you just set the "rendered" attribute to false? Of course, that would eliminate the commandLink completely from the page.

Disable delete button in Table Maintainance Generator

Hello all,
How to disable delete button in Table maintainance generator???

Hi Maya,
It is very interesting question. If you debug your table maintenance screen, the program of table maintenance screen will not have statically defined pf status. So you cannot exclude delete functionalities using the below statement.
SET PF-STATUS <the GUI status> EXCLUDING 'DELE'.
For viewing pf status SAP has programmed in dynamic manner using this FM VIEW_SET_PF_STATUS.
Before calling above FM you need to exclude delete function. Follow the following step for achieving this
Go to sm30. Put your table name and press on maintain push button. It will display table entries in maintenance screen.
Go to system->status
Click on program name.
Go to your flow logic of you table maintenance screen number.
It will have following code in flow logic

Command button does not commit unless hit twice

I'm using ADF/BC, 10.1.3.2 jdev. I have the following code in my backing bean:
    public String cardLost() {
        inputText12.setValue("1");
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding =
            bindings.getOperationBinding("Commit");
        Object result = operationBinding.execute();
        if (!operationBinding.getErrors().isEmpty()) {
            return null;
        return null;
The command button is defined as follows:
<af:commandButton
                                text="Save" disabled="false"
                                binding="#{find_student_mb.commandButton4}"
                                id="commandButton4"
                                action="#{find_student_mb.cardLost}"
                                immediate="false"/>When I hit the Save button the first time, the input text field (inputText12) changes to 1, but the data does not get commited to the database. (I have verified this in the database) If I hit the Save button again, the data gets committed.
Is there a way to update the field and commit the data with one button?
Thanks,
Bob

Hi,
commit doesn't execute before a field is submitted. So what you do is you submit a page then update the field (which then is not yet reflected in the submit) an call commit, which basically executes on no new data. In the second call you now submit the data shown in the field that then also gets commited. To get it commited on the first button press, set the field value to the binding layer (attribute binding or iterator binding )

Af:statusIndicator does not show busy icon when a command button is click

Hi Guys,
af:statusIndicator does not show busy icon or motion when a command button is click
I am working on an excel data upload functionality on .jspx page. I use “af:inputFile” file uploader to upload an excel file then process the data and store it as a list of objects in memory and display it in “af:table” table
I added “af:statusIndicator” to the page to show the user that the page is progressing while the data is uploading and when it is saving the data to the database.
In this case, when the “af:inputFile” is clicked to upload the excel file - the status indicator shows a progress icon (movement) which is expected and is good. However, after the data have been display in the table when I click on a command button that saves the data to the database – I expected the status indicator to start its busy motion but that is not happening. Whereas, the command button grayed out and is disable when I clicked the button until the operation is completed.
Is there any way to start the statusIndicator when a command button is clicked?
I tried the following options
*<af:statusIndicator id="si1_uploadStatus" partialTriggers="pc1:cb1 pc1:table"/>*
Where pc1:cb1 is the command button and pc1:table is the table
*<af:commandButton text="Submit Uploads" id="cb1"*
*disabled="#{!viewScope.batchUploadController.allSavable}"*
*partialTriggers="::infFilePath"*
*action="#{viewScope.batchUploadController.saveUploadedData}"*
*blocking="true"/>*
Thanks,

Can somebody please address this?
Thanks,

Command buttons best practice

Hello,
I would like to ask how others design their GUI with several command buttons (OK button Boolean).
For instance, there is a simple application where the user can start data acquisition by clicking on a button with text "Start monitoring". Instead of having another button with text "Stop monitoring", usually I just change the button label text into "Stop monitoring", so it is obvious to the user that again clicking on it will stop the monitoring process of the app (in the event case of this button I read out the actual label text with property node in order to decide which action to message to the DAQ loop from the GUI Event handler loop).
If I have another button with label text like "Start file record", I do the same way: after starting file record, I change the text to "Stop file record".
To avoid unnecessary extra programming, this button is only in Enabled state if the application is already in the "monitoring" state. Also, if there is an ongoing file record (+ DAQ obviously), the user cannot operate the "Stop monitoring" button. So depending on the state of the applications, some buttons are Enabled, some in "Disabled and grayed out" state.
I wonder how others are doing their GUI/application?
I am not sure if this is a good way to do, but at least I can avoid extra state check programming and minimizing the number of buttons...
Solved!
Go to Solution.

Also booleans can have three different images associated with them (well more for things like mouse over but that's not what I mean). You can have an image that is shown when the button it True, when the button is False, or an image that is shown when it is either False or True. So on top of having the text show "Start" or "Stop" I usally replace the True image and the False image with a start and stop icon. Customize the boolean control, and then right click and choose Import Picture From Clipboard and select the appropriate state.

Disable a button component onClick

hi,
I am work with JSF technology. I have a requirement based on command Button i.e..
can we create make a command button disabled on click and the request is to be send to the server
scenerio:
In my application if the user clicks multiple times the submit button. the application is throwing an exception. So I want to disable the submit button when the button is first clicked and the data is to be sent to the server.
I tryed this using JavaScript . I was able to disable the button on click but the request was not sent
can Anybody help me in solving this issue. I will be very thank full if i get the help.
thank you.

You can also use javascript instead.
onClick="window.setTimeout('document.getElementById(\'' + this.id + '\').disabled = true, 50);"
Dependent on the security requirements of your app you can't rely on this client side behaviour. The user could manipulate the request and invoke the action method, even if the button is disabled.

Controlling the desableing of command buttons

I have been having a great deal of trouble trying to work out how to control the command button such that if the rowset is null then the button is disabled. The trick is that the rowset is not defined by the view where the command button is located. The rowset is defined by a view which has a "view" command button which displays the specific row selected, then this view has a command button that will display the detail rowset of the selected master row, but if there are no detail records I want the button to be disabled. How can I do this in ADF JSF? If I use a backing bean to make the determination prior to the page rendering then how does the backing mean method set the parameter necessary to disable the command button? Any advice or tutorial that I can use is most appreciated. My goal with using ADF JSF effort was to demonstrate that a complex app could be generated with minimum coding, I would like to keep to this concept if possible. Thanks,
Michael

Wrong forum. You need the ADF or JDeveloper forums.
