How to get value from a textfield inside datatable

Hi!
I have a jsf Datatable with some rows. Inside of each row is a cell which contains a textfield. (the datatable shows products; each product is in a row; the textfield represents the number of pieces you want to buy)
Now my question is how to process each value the user inserts in the textfields on a next page?

Well let's say your datatable has a value binding to an ArrayList<SomeObject> stored in a backing bean .
<h:form>
<h:dataTable value="#{mybackingBean.valuesList}" var="value">
       <h:column>
             <h:inputText value="#{value.someObjectProperty}">
       </h:column>
</h:dataTable>
<h:commandButton value="submit" />
</h:form>when you will submit the form , the actual object ( at which row index you have edited ) on the ArrayList<SomeObject> will be updated .
This should work ... Try posting your whole form and perhaps we'll get the better picture

How to get value of a textfield which has been set as Renderd false.

Hi all
how to get value of a TEXTFIELD which has been set as Renderd false.
i am getting the value of this textfield from an lov but dont want to show it to the user.
getting error as:
attribute xxxx required for view object yyyyy.
pls help
naveen

You can create item inside your LOV region, set the item style to formValue. You can associate this to a View Object field. It can also act as mirror of any other text input field.
FormValue can hold the value and will not be diaplyed to user. You can read value from it controller
example
OAFormValueBean orgValue = (OAFormValueBean)webBean.findChildRecursive("OrgIdFormVal");
Or you can read it fro the VO associated with this form value.

How to get values from a TextFiled

This may be a newbie question, that's okay, because I'm new to JHeadstart.
I have a page for changing a user's password. The page has 3 fields (userid, oldpassword, newpassword) and a button (save). When the user clicks the button I want to capture the values the user is sending and run a SQL statement against the database with values from the textfields in the SQL statement.
I have a class that contains a custom method alterUser() that will do the SQL execution. The problem is that my values that show up in create(AttributeList attributeList) in the TextFields are showing up as null. See bottom of code below....
Suggestions?

Hi,
The BC4J create statement fires when the "New" button is pressed, so when an EMPTY record is created. It's normal that at that point all attributes are null.
What you probably want to do, is catch the "Save" process. You can do that by overriding the doDML method (menu: Tools - Override Methods). At that point the attributes should not be null anymore.
Hope this helps,

JSF:how to get value from dinamically generated HtmlInputText components�H�H

<h:panelGroup binding="#{dynamicInputGroupBean.group}"/>
public HtmlPanelGroup getGroup() {
          if (this.getSelectedComp() == null) {
               return this.group;
          FacesContext facesContext = FacesContext.getCurrentInstance();
          Application application = facesContext.getApplication();
          this.group = new HtmlPanelGroup();
          Set pSet = this.getSelectedComp().getParameterses();
          int size = pSet.size();
          this.instanceValue = new String[size];
          int i = 0;
          for (Iterator it = pSet.iterator(); it.hasNext();) {
               Parameters tempP = (Parameters) it.next();
               HtmlOutputLabel outputLable = new HtmlOutputLabel();
               HtmlInputText inputText = new HtmlInputText();
               inputText.setId("p" + i);
               String valueBindingExpression = "#{dynamicInputGroupBean.instanceValue["+i+ "]}";
               System.out.println(valueBindingExpression);
               ValueBinding valueBinding = application
                         .createValueBinding(valueBindingExpression);
               inputText.setValueBinding("value", valueBinding);
               outputLable.setFor(inputText.getId());
               outputLable.setValue(tempP.getParaname() + ": ");
               group.getChildren().add(outputLable);
               group.getChildren().add(inputText);
               i++;
          // group.getChildren().add(new HtmlInputText());
          return group;
     }as codes show above, i successfully genera HtmlInputText dinamicaly�C
but i got problems while i try to print those values...
after the the jsp page presents in my browser,
i input some words in the input components,
and then click a commandButton hold an action to print their value
action code :
String[] tempArray = this.getInstanceValue();
for (int i = 0; i < tempArray.length; i++) {
System.out.println(tempArray);
only NULL has been printed in the consol ....not the word i inputed!!!
so my question is how can i get values from those
dinamically generated HtmlInputText ????

This approach is odd. What's the functional requirement after all? You normally attach the inputtext value to a backing bean property and do the desired command button action which is attached to a backing bean action method. In this method you then use the value for the query.

How to get values from an IFrame...

Hi everyone. I have come to a complete stop i my project and need to ask the following: How do i get the values from an IFrame.
Situation: I have a main.jsp page that contains an IFrame(data.jsp). Data.jsp is basically made up of a bunch of checkboxes. The state of these boxes(checked or unchecked) is determined and set by a JAVA program and the results are then stored in a StringBuffer. Contents of Stringbuffer could look something like this: <tr><input type='checkbox' name='box0' CHECKED></tr>.
The StringBuffer in then presented in the IFrame(data.jsp) like so: <%=res.getInfo()%>
The user should be able to check or uncheck the boxes from the main.jsp page then when pressing a submit button the changes should be stored in a DBase.
After the submit button have been pressed i go into my Servlet's doPost() method for some basic processing. This is were the problem starts. I usally use HttpServletRequest.getParameter(String param) to get values from the main.jsp page. But these checkboxes are stored in the IFrame, so how do i go about to retrieve the values from data.jsp from the doPost() method or in some other way maybe. This is quite urgent and i hope that i have explained the scenario in enough detail.
Any help would be greatlly apritiated.
Best regards
Peter

How to get values from a stored package variable of type record ?

Sir,
In my JClient form, I need to get values from a database stored package variable of type record. And the values are retained in the JClient form for the whole session. The values are copied only once when the form is started.
What is the best way to do that ?
Thanks
Stephen

Stephen,
not sure what your model is, but if it is Business Components, I think I would expose the properties as a client method on the application module. This way all JClient panels and frames will have access to it. You could use a HashMap to store the data in teh app module.
If JDBC supports the record type, then you should be able to call it via a prepared SQL statement. If not, you may consider writing a PLSQL accessor to your stored procedure that returns something that can be handled.

How to get value from Thread Run Method

I want to access a variable from the run method of a Thread externally in a class or in a method. Even though I make the variable as public /public static, I could get the value till the end of the run method only. After that it seems that scope of the variable gets lost resulting to null value in the called method/class..
How can I get the variable with the value?
This is sample code:
public class SampleSynchronisation
public static void main(String df[])
sampleThread sathr= new sampleThread();
sathr.start();
System.out.println("This is the value from the run method "+sathr.x);
/* I should get Inside the run method::: But I get only Inside */
class sampleThread extends Thread
     public String x="Inside";
     public void run()
          x+="the run method";

I think this is what you're looking for. I hold up main(), waiting for the results to be concatenated to the String.
public class sampsynch
    class SampleThread extends Thread
     String x = "Inside";
     public void run() {
         x+="the run method";
         synchronized(this) {
          notify();
    public static void main(String[] args) throws InterruptedException {
     SampleThread t = new sampsynch().new SampleThread();
     t.start();
     synchronized(t) {
         t.wait();
     System.out.println(t.x);
}

How to get values from RT table

Hello friends ,
I want to get earned basic from RT table T-code - pc00_m40_clstr
how to get that values for wage types
gaurav

Hi Gaurav,
The Function Module u2018 PYXX_READ_PAYROLL_RESULT u2019 generically reads a complete payroll result, that is for all country versions, from file PCL2 or from the buffer. In doing so, the payroll result is transferred to the PAYROLL_RESULT parameter. In the calling system, this must be classified as a complex structure according to the 'PAYxx_RESULT' dictionary structure. u2018 xx u2018 is the ISO code for the country. Now the payroll result is in the parameter FS_PAY99_RESULT. In this parameter the RT table is considered and the required values are moved into a internal table (say T_RT).
Regards,
Swapna.

How to get values from the page excpet pagecontext.getparameter

i have a requirement wherein i am passing paramteres from the "submit" button.but the problem being that,i have multiple rows in my page.what is happening is that my "submit" button is passing the values of the previous row,instead of the current row.this is i think because "commit" gets called later and params are passed before it.
how do i solve this problem
or if i can get to get paramteres in a advance table layout,i l be able to achieve my requirement.beacuse in advance table layout,i am not able to do pagecontext.getparameter("---" of the item

thanks guys,
i did try working with row refrence but it returns a null only.
my requirement was that i had update functionality as well as "add new rows" on the same advtbl bean.an whenevr i click on "add new row" and submit,i was always gettin the parameters for the previous row.
now,i have got a workaround to that,by having a radio button to select rows to update and whenever i click on "add new rows" ,i disable the radio button,and get the handle based on the value from radio group.
but still row refrence dint work for me.i will appreciate if sum1 can send me the code

How to get values from a query string in URL in a jsf page?

if i have a url, http://my.com/?name=john+smith, how do i get the values from that url in a jsf page and then pass those values to a servlet?
i know how to do that in jsp using "request.getParamter("name")" and save it in a bean and then forward to a servlet. But what about in jsf?

Hello,
Try this:
Map requestMap = FacesContext.getCurrentInstance().getExternalContext().getRequestMap();
String name = (String) requestMap.get("name");If isn't worked one of these methods probably will solve your problem.
FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap();
FacesContext.getCurrentInstance().getExternalContext().getRequestHeaderMap();hth.

How to get values from afLiterator ?

Hi All,
I have a grid populated records using af:Iterator. Row are populated from the List model(say product list). The iterator component i binded in the bean.
Now i have showing 5 records per page. total 3 pages are there.
There is a boolean check box for each rows. and a common check box to select all the rows in the page.
I dont know how to get the rows of current set when i select the SelectAll checkbox, similarlly i have to do the same when i go to page 2 of the iterator.(page 2 means next range of records in the iterator)
My requirement is using the af:iterator not af:table.. please help

Hi,
af:iterator does i) not keep track of selection states and ii) stamp data
i) The selection state needs to be tracked with <f:attribute ...> tags added to the check box component. The value of the attribute should identify the row (ideally by a unique key). The name of the attribute is up to you. When you iterate over the selected check boxes you call getAttribute() on the check box component to access your custom attribute for identifying the row instance
ii) rows are no individual instances and there fore cannot be directly accessed. af:forEach may be a better fit for your use case as it created component instances that then allow you to call the JSF parent container and getChildren on this. You then look for the checkbox component instances and verify its selection state. For selected components you the access the custom attribute
