Datatable categorization refresh
Hi All,
I have a datatable which generates the hierarchy as shown in attachment.The table is populated from an ArrayList which has an object of type Publication.
Class Publication
String category = null;
String subcategory = null;
}Category Subcategory Topic
Focus Reports sub1 topic1
Focus Reports sub1 topic2
Focus Reports sub3 topic3
Risk Perception Natural Catastrophes topic4
The tree structure is obtained by having one rowcategory on category and second on subcategory. The problem is when i add a new Publication to the array list with Category as "Focus Reports" and Subcategory as "sub1"
table gets refreshed but always adds the new entry at end..that is at "Risk Perception---> Natural catastrophes" instead at "Focus Reports--->sub1". Ichecked the object tostring and looks propers.. i am not able to figure out the reason.. why isn't the categorization working properly.. does the order of objects in the list mater..
Please suggest how can i refresh the datatable correctly.
Thanks in advance
I'll try to explain better......
I have a dynamic Table created, with dynamic columns...
and it is working well...
but when I change a combo, and submit, I clear the columns of table, and add other new columns, dynamically....
but, the page is equal before, and when I refresh the page again, it works and the correct columns are displayed.....
How I force table to be displayed correctly at first time?????
anyone?
thanks

Refreshing specific cell in dataTable?
Hi
How do I get a dataTable to re-render a specific cell? As an example, consider Bean listed below. Initially, the dataTable displays the values as iterated over Bean.lines. Later in response to a user action (see Bean.updateLine), I'd like the appropriate cell in the dataTable to be refreshed (without of course having to press a 'Refresh' button).
How do I achieve this with dataTable?
public class Bean {
private List<Line> lines = new ArrayList<Line>();
public List<Line> getLines() {
return lines;
// called (in response to a user action for example) to refresh a specific line value
public void updateLine() {
lines.get(0).setVal("some new value");
public class Line {
private final String id;
private String val;
private Line(String id) {
this.id = id;
public String getId() {
return id;
// calling this must trigger the dataTable to refresh the appropriate cell (ideally)
// or else the entire dataTable in the browser
public void setVal(String val) {
this.val = val;
public void getVal() {
return val;
} // Line
<h:dataTable value="#{bean.lines}" var="line">
<h:column>
<h:outputText value="#{line.id}"/>
</h:column>
<h:column>
<h:outputText value="#{line.val}"/>
</h:column>
</h:dataTable>Help much appreciated
LanceThanks, AJAX is doing the trick nicely.
For the benefit of a future question, I'm using onclick="doSomething()" on a component within the table (a selectBooleanCheckbox in my case).
Main JavaScript / AJAX:
<script type="text/javascript">
function doSomething(elementId) {
var rowNum = elementId.split(":")[2]; // position in table
var someId = document.getElementById("form_id:table_id:" +
rowNum + ":textbox_id").innerHTML;
var url = "handler?cmd=MY_SERVLET_CMD" + // handler points to HandlerServlet
"&some_id=" + encodeURIComponent(someId) +
"&row_num=" + encodeURIComponent(rowNum);
if (typeof XMLHttpRequest != "undefined") {
req = new XMLHttpRequest(); // AJAX
} else if (window.ActiveXObject) {
req = new ActiveXObject("Microsoft.XMLHTTP");
} else {
alert("Browser not supported!");
req.open("GET", url, true); // true = asynchronous AJAX call
req.onreadystatechange = doSomethingCallback; // only if asynchronous
req.send(null);
</script>Callback function (invoked on return from the servlet - see reference in doSomething above):
<script type="text/javascript">
function doSomethingCallback() {
if (req.readyState == 4) { // checks are needed else we react before response is complete
if (req.status == 200) { // see comment above
var prefix = "form_id:table_id:";
var suffix = ":checkbox_id"; // we want to update all check boxes - see below
var msg = req.responseXML.getElementsByTagName("message")[0];
var lineCount = msg.getElementsByTagName("line_count")[0].childNodes[0].nodeValue;
var rowNum = msg.getElementsByTagName("row_num")[0].childNodes[0].nodeValue;
var checkAll =
document.getElementById(prefix + rowNum + ":check_all_id"); // another check box that determines state of check boxes below
var lineCheckId = ""; // line checkbox element
for (var i = rowNum, n = parseInt(rowNum) +
parseInt(lineCount); i < n; i++) {
lineCheckId = prefix + i + suffix;
document.getElementById(lineCheckId).checked = checkAll.checked; // update the DOM
} // status
} // readyState
</script> -
I have two datatables on a single JSF page.
A Master /slave model
page
DATA TABLE A
DATA TABLE B
DataTable A
Row 1
Row 2
Row n
When I click on Row1 DataTable B is populated with rows corresponding to Row 1
But the problem is when I sort DataTable A using some column; DataTable B's content is vanished..
How can i avoid wholoe page being reloaded/refreshed?
thanks
Satish
Bostonprobably datatable b is populated by a request scoped bean?
some code fragments would be useful... -
Refresh dataTable for Search function
Hi,
I have a page that contains a dataTable and search function for the dataTable. Basically once i clicked into that page it will display the current day records for me. At the below of the dataTable, it have a search function. So once i click the search button with my search criteria, how i refresh my dataTable to display the records?
My dataTable already bind with the current day
<h:dataTable id="outbound" value="#{Outbound.current}" var="sms" bgcolor="#F1F1F1" border="1" cellpadding="0" cellspacing="0" first="0" rows="10" width="100%" columnClasses="outcol1,outcol2,outcol3">
<h:column>
<f:facet name="header">
<h:outputText value="Date-In" />
</f:facet>
<h:outputText value="#{sms.datein}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="SMS Date" />
</f:facet>
<h:outputText value="#{sms.smsdate}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Del Date" />
</f:facet>
<h:outputText value="#{sms.dndate}" />
</h:column>
<h:column>
</h:dataTable>So how to refresh the dataTable? Unless I do a rebind where I have one dataTable is for current day and another one is for search?
Thanks.adrianclw wrote:
Yup. I would like to re-render my dataTable after i clicked Search button. So the dataTable will display my search result.
So existing dataTable unable to do it? Currently I'm using Apache Tomahawk for my dataTable.
If you want to re-render the datatable without submitting the page, you will have to use Ajax. If you can allow submitting of page, then just change(refresh) the list in the backing bean that you have value-bound to the h:datatable in jsp.
Another thing, I'm not sure i'm doing it correct or not. Now my dataTable is bind with the getCurrentDay function. So can i re-render it? Will it re-render and getting the same output since it already tied with current day function.
See the above comment. -
Can not refresh data int the report...
Application on C#.
Steps:
1. Get Report without data from the database
2. Change the dataconnections in report to the current user
3. refresh data on the report (FilePath = TempFilePath)
4. Resave report file with data
5. Automatically open CrystalReportsViewer2008 and load the report
Result
On developer machine is allright, but on the user machine data isn't refreshed. Therefore CrysrtalReportsViewer2008 can't open report. It say that check the SaveDatawithReport parameter.
In process I found that in temp directory on user pc, didn't creates some temprorary files which creates on developer PC. Why? Help me please.
Sorry for my English.There is the code of my programm

Problem with binding in h:dataTable

lines.add(new Line("one"));
lines.add(new Line("two"));
lines.add(new Line("three"));
public List<Line> getLines() {
return lines;
* Nested class in order to access containing class
* properties etc.
public static class Line {
//private boolean lineSelected = false;

} // Line
}The setup works when I use value="#{line.lineSelected}" (assuming the property is defined as boolean in Bean$Line) but as soon as I use a binding, I get the following exception:

Thanks a lot, both of your replies are immensely instructive. Maybe a little background on what I'm trying to do. In the table, I have header rows with dependent line rows. When a check box is ticked in the header, I want the corresponding check boxes in the dependent lines to be checked automatically (in slave fashion and ideally without using JavaScript). My idea was to update the bound components (for the lines) from within the Bean (in response to change on the header). However, given there's only a single component for each column in the table, this of course doesn't make sense.
I'm trying to get to the typical MVC workflow of a) user updates a View component, b) Controller detects the change and updates the Model, c) The Model fires a property change event, which the View detects and updates appropriately. What's the way to achieve this in JSF (by design)?
Here's a simple fragment (which does not work):
<h:dataTable value="#{bean.lines}" var="line">
<h:column>
<h:outputText value="#{line.id}"/>
</h:column>
<h:column>
<!-- (1) This is the master and (2) should refresh on update here --/>
<h:selectBooleanCheckbox onchange="submit()" value="#{line.lineSelected}"/>
</h:column>
<h:column>
<!-- (2) This is the slave and I want this to update in response to a change of (1) above --/>
<h:selectBooleanCheckbox value="#{line.slaveSelected}"/>
</h:column>
</h:dataTable>In the setter method for lineSelected, I'm setting slaveSelected to the new value but the View is not refreshing based on this. How do I get the View to update (each dependent line) based on the new values for slaveSelected?
Thanks again

How to refresh a crystal report automatically ?
I deployed my website(asp.net/c#) in IIS 7.5, when i click on the button to open the page that contain the report, i get a blank page but when i refresh the page (F5) it's ok. my question is: how can i open the page that contain the report file directly
without refresh?Tricky to guess without seeing any code.
Here's some example code which fills and shows a report.
protected void Page_Load(object sender, EventArgs e)
ReportDocument rd;
DataTable dt = (DataTable)Session["xxxxx"];
// Tricky bit here is to make the name of the datatable match what the report expects
dt.TableName = "DataTable1";
rd = new ReportDocument();
rd.Load(Server.MapPath("Reports\\xxxxReport.rpt"));
rd.SetDataSource(dt);
rd.Refresh();
CrystalReportViewer1.ReportSource = rd;
CrystalReportViewer1.RefreshReport();
CrystalReportViewer1.DisplayGroupTree = false;

One reason why commandLink doesn't work in dataTable
Ok, so I think I've got an explanation why commandLink doesn't work in dataTable when the model bean is request scoped. Maybe somebody can tell me if I'm wrong.
I have a model bean that generates table rows based on some input criteria (request parameters).
So, we validate the inputs, apply them to the bean and render the page. Once the inputs have been applied to the bean, a request for table rows returns rows, no problem.
However, we put a commandLink in each row, so we can expand the details. Maybe we even get smart and repeat the input row-generating criteria as a hidden field in the page.
Unfortunately, when the user hits the commandLink, the list page simply refreshes, maybe even w/out table rows. The user doesn't get the details page as expected.
Why not?
Because: in the DECODE phase (even before validation and before "immediate" values have had their valueChangeListeners called), we ask the model bean for the table rows, so we can decode the commandLinks. Unfortunately, in "decode" phase, the request-scoped model bean has not had its row-generating criteria updated (that happens in the "update model" normally, or at the END of the decode phase if we got cute by (1) setting the "immediate" attribute on the row-generating criteria to "true" AND (2) set a valueChangeListener to allow us to update the model bean early. The END of the decode phase isn't good enough -- in the middle of that phase, when we're attempting to deocde commandLinks, the model bean has no citeria, so there's no row data. No row data means no iteration over commandLinks to decode them and queue ActionEvents. So, we march through the rest of the phases, process no events, and return to the screen of origin (the list screen) with no errors.
So, what's the solution?
One solution is to make the model bean session-scoped. Fine, maybe we can store a tiny bit of data in it (the search criteria), so it's not such a memory drag to have it live in the session forever. How do we get that data in? A managed property in faces-config.xml with value #{param.PARENT_KEY} won't work because it's assigning request-scoped data to a session-scoped holder. JBoss balks, and rightly so. Do we write code in the model bean that pulls the request parameter out of thin air? (FacesContext.getExternalContext()....) I don't really like to code the name of a specific http request parameter into the bean, I think it's the job of the JSP or faces-config.xml to achieve that binding (request parameter to model propery). Plus, I'd be sad to introduce a dependency on Faces in what was previously just a bean.
Is there a better way?
In my particular situation, we're grafting some Faces pages onto an already-existing non-Faces application. I don't get the luxury of presenting the user an input field and binding it to a bean. All I've got to work with is a request parameter.
Hmm, I guess I just answered my own question. if all I've got to work with is a request parameter, some ugliness is inevitable, I guess.
I guess the best fix is to cheat and have the bean constructor look for a request parameter. If it finds it, it initializes the criteria field (which, in my case, is the key of an object that has a bunch of associated objects (the rows data), but could be more-general d/b search criteria).
(I looked at the "repeater" example code in the RI, but it basically statically-generates its data and then uses 100% Faces (of course) to manage the paging (where "page number" is essentially the "criteria").
Comments? Did I miss something obvious?
John....or I could just break down and do the thing I was hoping to avoid (outputLink instead of commandLink):
<h:outputLink value="/faces/Detail.jsp">
<f:param name="PARENT_KEY" value="#{bean.parentKey}"/>
<h:outputText value="#{bean.label}"/>
</h:outputLink>It's still a "hardcoded" parameter name, but at least the binding is in the JSP and faces-config.xml, not the bean Java code. -
Error due to drop down menu in the dataTable
I have a data table which has a drop down menu in one of the table columns. When the drop down menu is disabled, every action in the page works (click on it, and it does what it does). When the drop down menu is enabled, every action (with one exception) in the page does not work (click on it, it refreshes the page, but the action is not fired). I cannot debug the thing because the action is not fired at all.
The exception is that for buttons that is marked as immediate, it works. I created an inline message, and wire that to the dropdown menu. I do not see any error. Looking into the log file, I do not see anything.
I was suspecting maybe conversion error. The data value for the drop down menu is integer (I try both setting the convert to integer and nothing). Even there's error in conversion, there should be error message showing up (in the inline message box).
So, again, how do I diagnos this, and to find out what is going on?
Thank you very much.
Vh.Thank you for your attention.

h:dataTable re-rendering problem...
hi friends,
In my project i am using JSF and a4j .I am getting re-rendering problem with <h:dataTable> in mozilla it is working fine but in IE6 the dataTable is not re-rendering ..
code is:
<a4j:commandButton value="#{rb.New}" onmouseup="javascript:openModalWindow('/NGL/faces/jsp/circulation /ILLPlaceILLRequest.jsp','','dialogWidth:500px;dialogHeight:500px;status:no;scrollbars:yes;top:200;left:200')" >
<a4j:support event="onmousedown" action="#{requestApprove.newActionPerformed}"/>
<a4j:support event="oncomplete" reRender="illDetails"/>
</a4j:commandButton>
my task is:
when i press the New button another jsp page will open in modal dialog after closing the dialog the table should re-render...

Edited by: Venkat_quill on Oct 30, 2008 3:50 AMthanks for your reply...
I have already tried this case but, the datatable is not re-rendering ...
I got below solutions..
<a4j:commandButton value="#{rb.New}" onmouseup="javascript:openModalWindow('/NGL/faces/jsp/circulation /ILLPlaceILLRequest.jsp','','dialogWidth:500px;dialogHeight:500px;status:no;scrollbars:yes;top:200;left:200')" >
<a4j:support event="onmousedown" action="#{requestApprove.newActionPerformed}"/>
<a4j:support event="oncomplete" action="#{requestApprove.clearData}" reRender="illDetails"/>
</a4j:commandButton>Why i followed this case this i have Add,Edit ,Delete and Refresh action on datatable.In Edit case i need to set some values in the dialog this also working fine with following code..
<a4j:commandButton value="#{rb.Edit}" onmouseup="editRequest()">
<a4j:support event="onmousedown" action="#{requestApprove.editActionPerformed}" reRender="msg,msgmode"/>
<a4j:support event="oncomplete" action="#{requestApprove.clearData}" reRender="illDetails,msg,msgmode"/>
</a4j:commandButton>But this problem is oncomplete event is not working in the Internet Explorer.... -
Use dpendent dropdowns in dataTable
The problem is how to populate/refresh the item list of a dropdown menu in a row af a dataTable according to the changes of an other component in the same row.
As an example consider the case when the rows of the table corresppond to Project entities, and for each project we can assign a departement and a project leader among the employees of the selected departement. NOw if the user select a departement for a project then the dorpdown for project leader should be populated with the employees of the selected departement.
I had two ideas but unfortunately none of them works. The first one is to generate the list of SelectItems in the Project entity (not a good programming practice). That is
<f:selectItems value="#{project.projectLeaderSelect}">so in the getProjectLeaderSelect() method of the entity we have information about the selected project leader.
The problem of this solution that the JSF framework does not allows us to bind input elements to none managed bean properties. I got exception - I suspect that was the reason.
The other way would be to send request parameters when populating dropdowns, but unfortunately getters are called several times, and the sent request parameters may be not living at any call.
At the end I solved the problem a bit strange way. I generated a prepopulated project leader dropdown for each possible departement, and rendered only one according to the present value of the departement attribute of the project. Of course, it is not a general enough way but for our problem was working, the possible values of both dropdowns were static.
I am still looking for a better solution.Hi,
Please go through the sample application AppModel which is available at:
http://developers.sun.com/prodtech/javatools/jscreator/reference/codesamples/sampleapps.html
Hope this helps.
Thanks,

How do you reset inputText values in a dataTable?
I'm having what must be a simple and common problem,
but nothing I've tried has solved it. I want to be
able to refresh (reset) the inputText field values in a dataTable.
I have a dataTable that holds required inputText components.
I want to have a "cancel" button which would abandon any edits
on these components and refresh (reset) them with their backing values,
as well as removing the last row from the table (used to enter a
new record). Because the inputText components are required,
I made the cancel button immediate. I don't know what code I can
put in the button's actionListener. Right now, the displayed values
survive the round trip to the server and back to the browser, but
I want them to be reset to their backing values.
Here is the page, and the backing bean of a test example:
<%@ include file="../include/taglibs.jsp" %>
<h:dataTable id="table" value="#{pc_Test.list}" var="x">
<h:column>
<h:panelGroup>
<h:inputText id="label_value" required="true" value="#{x.value}" />
<h:message for="label_value"/>
</h:panelGroup>
</h:column>
<f:facet name="footer">
<h:panelGroup>
<h:commandButton id = "btnn" value="new row" actionListener="#{pc_Test.newRow}" />
<f:verbatim> </f:verbatim>
<h:commandButton id = "btnu" value="update" actionListener="#{pc_Test.update}" />
<f:verbatim> </f:verbatim>
<h:commandButton id = "btnr" value="cancel" immediate="true" actionListener="#{pc_Test.cancel}"/>
</h:panelGroup>
</f:facet>
</h:dataTable>
<f:verbatim>Summary=</f:verbatim>
<h:outputText value="#{pc_Test.listString}" />
package pagecode;
import java.util.ArrayList;
import java.util.List;
import javax.faces.event.ActionEvent;
public class TestPage {
public static class Example {
public Example(String value){this.value = value;}
public String getValue() {return value;}
public void setValue(String value) {this.value = value;}
public String toString(){return getValue();}
private String value;
public TestPage(){
list.add(new Example("a"));
list.add(new Example("b"));
list.add(new Example("c"));
public List getList() {return list;}
public String getListString() {return list.toString();}
public void update(ActionEvent event){}
public void cancel(ActionEvent event){
if (list.size()>3)
list.remove(list.size()-1);
public void newRow(ActionEvent event){
list.add(new Example(""));
private boolean readOnly;
private List list = new ArrayList();
}If it makes a difference, my implementation of JSF is MyFaces. Thanks!bump
I'm not happy with having javascript reseting fields in a table before submitting:
there's a noticable screen flash, and I'd like a server-side solution anyway.
Question: UIInput has methods getSubmittedValue and setSubmittedValue,
so I can use these to ignore or clear submitted values when I press an
immediate command button. This takes care of subclasses like HtmlInputText
but not for data tables. Is there a way to manipulate all the submitted values
of a data table? -

I am starting with Visual web java server faces, and I want to fill a Table using an information from MySQL data base, i am trying to modify a example code I have found on netbeans totorials but they are using droplist and I want firts to use a texfield to set a "name" and button to search using a MySQL query to seek on data table and get the return and set it to Table.
Basicly I dont Know HOW to connect a data base using same code like a desktop application but in Visual Web Java Server Faces.
thank you in advance.
Miguel V.Hi;
I hava done this code but still geting a mistake with tomcat
Next steps i follow to conectand display on data table:
1.-Create conecction with MySQL usen service.
2.-On service drag "directorio" to Table
3.-Binding all objets (Textfield1, Table and Button)
4.-On button1 create the next code:
Object optener =3;
//set the dataprovider with element number 3, on DIRECTORIO.ID of datatable directorio
directorioDataProvider.setCursorRow(directorioDataProvider.findFirst("DIRECTORIO.ID", optener));
//Get the row with same ID=3
getSessionBean1().getDirectorioRowSet().setObject(1, optener);
//Shows the inf on table
getSessionBean1().getDirectorioRowSet().execute();

Get DataTable From SSRS Server Report
HI,
I am using SSRS reporting service. In my web application, I am showing SSRS Server Report in my custom rdlc viewer.
I am getting report definition by ReportingService2005 Web Service and setting report parameters from UI.
My Code Snippet Like Below:
RptViewer.ProcessingMode = ProcessingMode.Remote;
IReportServerCredentials irsc = new CustomReportCredentials(System.Configuration.ConfigurationManager.AppSettings["rsUser"], System.Configuration.ConfigurationManager.AppSettings["rsPassword"], System.Configuration.ConfigurationManager.AppSettings["rsDomain"]);
RptViewer.ServerReport.ReportServerCredentials = irsc;
RptViewer.ServerReport.ReportServerUrl = new Uri(System.Configuration.ConfigurationManager.AppSettings["SSRSSVR"]);
RptViewer.ServerReport.ReportPath = my_reportPath;
RptViewer.ServerReport.SetParameters(reportParameters);
RptViewer.ServerReport.Refresh();
MY Question:
This Code directly show the report. But my requirement is not to showing the report if the datatable return 0 rows.
How can I get the datatable from server report just before loading the report? Is there any way?
Getting the datatable from server report is also necessary for another reason. I want to export the report to excel (only data not rdlc built in excel format), and for that I need the datatable available.
Since the report is already loaded, I do not want to query again to pick the datable.
So, Is there any way to get the resultant datatable before the server report loaded in report viewer.
