this data table is not re-rendered even i have specified id of datatable in the reRender attrbute of <a4j:commandLink
note that
i have also specified other ids in the reRender attrbute of <a4j:commandLink And others work fine but the DATATABLE dont .

Get called back as the data table is being rendered

Hello:
I have a datatable, like this:
<t:column>
<f:facet name="header">
<t:outputText value="Process" style="font-weight: bold" />
</f:facet>
<t:commandButton id="ProcessButton" styleClass="sbttnHeader"
actionListener="#{ProcessQueueBBean.processAction}"
value="#{ProcessQueueBBean.processButtonNames[dbRow.status]}" >
</t:commandButton>
</t:column>I need to get called when the data table rows are being rendered. The reason I need to get called is that some columns have conditional data depending on the other values in the same row
Any ideas?
Thanks for your help

I don't know i've never tried this in the way you need it but let me know if it works.. in the <column tag render=> I know you can check infor
so have render = "#{row.num+row.othernumber >0}"
that probably will work .. like i said I never tried it in a table column.. Let me know if it works

JSP Data table - Rendering for command buttons.

Hi All,
We are designing a JSP page where results from table have to be thrown on a data table. (h:dataTable)
Based on one column value on the data table, we need to render a command button for each row of data table.
For example, I select the employees from a table and throw it on data table.
Only for those employees where address is not present, I need to enable an "Update address" command button.
(Command button "Update address" is also part of data table.)
Is it possible to accomplish this on a data table?
If so how should we code the "rendered" tag of the command button in data table.
Any help would be greatly appreciated.
Thanks.

Sounds like the JSF forum would be a closer alignment, but in general
- retrieve your information from the database into a list of Employee beans.
- Have your h:dataTable use the list of Employee beans as a datasource
- have the rendered attribute of your update button depend on the value of employee.address maybe #{empty employee.address}
cheers,

A data table in one column of a dynamic data table

Hi , I have to design a dynamic data table(with dynamic columns and data) which looks as the following
DETAILS      NAME      ROLE NUMBER     CLASS     SECTION
15     MATHS     SURESH     15     10     A
20     SCIENCE
25     ENGLISH
15     MATHS     SURESH     15     10     A
20     SCIENCE
25     ENGLISH
The data in the column 'DETAILS' should have inner table. The data in this inner table should have hyper links. If there is no inner table infor mation there shold be an image with hyperlink. This data table should also have pagination and sorting features. Please send me some example code for this. Please help me out as i have client demo on monday

You may find this example useful: [http://balusc.blogspot.com/2006/06/using-datatables.html#NestingDatatables].
To toggle between a nested datatable and a hyperlink with image just use the rendered attribute. E.g.
    <h:column>
        <h:dataTable rendered="#{!empty dataItem.innerList}">
        </h:dataTable>
        <h:commandLink rendered="#{empty dataItem.innerList}">
        </h:commandLink>
    </h:column>

Weird problem with mysql query and data table buttons !!!!

Hi,
I'm using jsc 2 update 1 on windows and mysql 4.1 . I have a page with a data table. One column of the data table contains "Details" buttons.
Source query for the table is :
SELECT tbl_tesserati.idtbl_tesserati idTesserato,
tbl_tesserati.num_tessera,
tbl_tesserati.nome,
tbl_societa.codice_meccanografico

The tbl_tesserati.data_nascita is a mysql date field.
The click event handler code for the "Details" Button is:
public String btnModificaTesserato_action() {
        try{
            TableRowDataProvider rowData= (TableRowDataProvider)getBean("currentRowTesserati");
            getRequestBean1().setId_tesserato((Long)rowData.getValue("idTesserato"));
        } catch(Exception ex) {
            log("errore nella query",ex);
        return "dettaglioTesseratoSocieta";
    }When i run the project and open the page the table is correctly rendered and populated with some rows. But when i click on details button nothing happens, the page is simply reloaded.
If i set a breakpoint in the code line TableRowDataProvider rowData= (TableRowDataProvider)getBean("currentRowTesserati");the debbuger does not stop the code execution ! As if the button was never clicked!
I tried to modify the source query to :
SELECT tbl_tesserati.idtbl_tesserati idTesserato,
tbl_tesserati.num_tessera,
tbl_tesserati.nome,
tbl_societa.codice_meccanografico

Using this query everything works well !! The click handler works and the debugger too !!
I changed only the AND in OR !!!
I also tried to change mysql-x-x-connector driver but without solving my problem.
Can someone help me ?
Thanks

You'll find that it is more to do with the way MySql deals with dates than anything else! Depending on how your date field is setup, then try using a BETWEEN statement for those 2 lines in your first query e.g.
AND ( tbl_tesserati.data_nascita BETWEEN ? AND ?)
The date column needs to be in the ISO format to work. If you examine your second query output, you might discover that the output is only going to refer to one parameter (probably the OR one). Did you manage to view the output logs from the application server? You would have got an idea from there with a message like stating a conversion error'.
Alternatively, you could try using the to_days() function and convert it directly to a number which would be a lot easier to deal with. For example:
AND to_days(tbl_tesserati.data_nascita >= ? )
AND to_days( tbl_tesserati.data_nascita<= ? )
Or try the BETWEEN version with to_days() and see what you get.
More info about date formatting (v5) here:
http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_to-days
Before I forget, sometimes you may need to treat dates as Strings rather 'Long' as you did.
As a matter of interest, did you try your query in a different piece of software?
If my queries are a little more complicated, I tend to try MySql queries out in the free MySql query browser and also double check in another to verify certain issues. I found it easier to develop SQL in a seperate program then import the final version to JSC making the required modifications for parameters.

How to link label with an input field in data table?

I am curious if there is a nice way to link a label to input field in a data table directly in JSP? Data filling the table are dynamically bounded.
Sample, simplified code below. Values of "label" property are unique in the collection binded to dataTable.
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root version="1.2" xmlns:f="http://java.sun.com/jsf/core"
     xmlns:h="http://java.sun.com/jsf/html"
     xmlns:jsp="http://java.sun.com/JSP/Page">
     <jsp:directive.page contentType="text/html;charset=UTF-8" pageEncoding="UTF-8" />
     <f:view>
          <html>
          <body>
          <h:dataTable value="#{screen$monitoring$errorlog$CorrectHopper.dataset}" var="DATA_ROW">
               <h:column>
                    <f:facet name="header">
                         <h:outputText value="Name" />
                    </f:facet>
                    <h:outputLabel value="#{DATA_ROW.label}" for="#{DATA_ROW.label}_id" />
               </h:column>
               <h:column>
                    <f:facet name="header">
                         <h:outputText value="Value" />
                    </f:facet>
                    <h:inputText value="#{DATA_ROW.label}" id="#{DATA_ROW.label}_id" />
               </h:column>
          </h:dataTable>
          </body>
          </html>
     </f:view>
</jsp:root>
returns:
17:39:01,390 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
java.lang.IllegalArgumentException: #{DATA_ROW.label}_id
what is related to EL expression in h:inputText's "id" attribute.
Is there any other way to bind label with dynamically created input field in JSP? Do I really have to bind input field directly to component objects with "binding" and set IDs manually with setId() (what is ugly solution because it moves View related logic to Model layer)?

I've thought of using EL because I have to somehow
link a label to an input field dynamically. Somehow? Dynamically? Just use plain text :)Well... just look at my code snippet (notice: we want to join the pairs of labels and text boxes placed in a datatable [or any other repeater-like component rendering properties of objects from a collection]):
<h:dataTable value="#{screen$monitoring$errorlog$CorrectHopper.dataset}" var="DATA_ROW">
<h:column>
<f:facet name="header">
<h:outputText value="Name" />
</f:facet>
<h:outputLabel value="#{DATA_ROW.label}" for="#{DATA_ROW.label}_id" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Value" />
</f:facet>
<h:inputText value="#{DATA_ROW.label}" id="#{DATA_ROW.label}_id" />
</h:column>
</h:dataTable>
and what is your idea of using plain text as "id" attribute value in this case? :)

Michal

Jsf data table component + print null cell

I am using the jsf data table component and binding the column values to a backing bean.
<h:dataTable binding="#{backing_showDifferences.dataTable2}"
id="dataTable2">
<h:column binding="#{backing_showDifferences.userColumn1}"/>
<h:column binding="#{backing_showDifferences.userColumn2}"/>
<h:column binding="#{backing_showDifferences.userColumn3}"/>
</h:dataTable>
- some code from my showDifferences.java
HtmlOutputText column1Text = new HtmlOutputText();
vb =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{users.uclass}");
column1Text.setValueBinding("value", vb);
usercolumn1.getChildren().add(column1Text);
HtmlOutputText column2Text = new HtmlOutputText();
vb =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{users.ue1}");
column2Text.setValueBinding("value", vb);
usercolumn2.getChildren().add(column2Text);
HtmlOutputText column3Text = new HtmlOutputText();
vb =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{users.ue2}");
column3Text.setValueBinding("value", vb);
usercolumn3.getChildren().add(column3Text);
ResultSetDataModel dataModel = new ResultSetDataModel();
dataModel.setWrappedData(rs);
dataTable2.setValue(dataModel);
The raw HTML:
<table id="form1:dataTable2" class="iuptable" border="1">
<thead>
<tr>
<th scope="col">Heading 1</th>
<th scope="col">Heading 2</th>
<th scope="col">Heading3</th>
</tr>
</thead>
<tbody>
<tr>
<td>some data in this column</td>
<td>X</td>
<td></td>
</tr>
<tr>
<td>Some more data in this row</td>
<td>X</td>
<td></td>
</tr>
</tbody>
</table>
My problem is this...in the raw HTML the <td></td> tag is not formatted nicely on my table output. I have lines around my entire table and each cell within it. When the <td></td> prints there are no lines. I am new to the JSF table data component, but if I were writing some JSP or servlet code I would check that if value was null I would append an &nbsp to the <td> tag (ex. <td>&nbsp</td>) and the table would be formatted properly. The backing bean that I am binding to is pulling the data from a database table...so my sql looks like this:
SELECT uclass, ue1, ue2 from table1; my problem is when ue1 or ue2 is a null value.
Any ideas would be greatly appreciated!

Hi,
the h:dataTable belongs to the JSF Reference Implementation from Sun, not to Oracle ADF Faces. The rendering is within this component set and I suggest to report your issue on one of the SUN forums (http://forum.java.sun.com/forum.jspa?forumID=427) as we have no handle to e.g. fix an issue if it exists in the component set.

Expand All and Collapse All with Data table

Hi Guys,
     I have a data table as shown in code pasted . where the first and second column have row category which gives a categorization with a twisty.
     When i click on the twisty or item name the level beneath it expands. Eerything works fine.. but i need to have to links     Expand All and Collapse All which when clicked open the entire hierarchy or collapse it. Can anyone suggest a way of doing. Can it be done using javascript, I am not comfortable with java script .If someone has done this before please share the piece of code.Also please suggest the different ways of doing it. I am using RAD 7 and IBM JSF components.

Hi Naamkeek,
Per my understanding that you have added the Expand All and Collapse All button in an drill down report by adding the "Go to report" action, now you got the report always refresh and return to the first page, right?
I have tested on my local environment and can reproduce the issue, no matter whether to add two buttons or using the parameter to do the Expand All and Collapse All, it is always return to the first page.
Gernerally, SQL Server Reporting Services does a postback while clicking a expand/collapse icon. SSRS re-renders reports because it need to regenerate the pages to fit the defined width & Height. That is why SQL Server Reporting Services reloads
the whole report.
This is by design. And, currently, we are not able to turned it off.
I would suggest you submitting a wish at
http://connect.microsoft.com
If the service requests frequently, we may include it in the next release.
Appreciate your understanding, and if you have any more questions, please feel free to ask.

Granularity of data tables for analysis

Hi Gurus,
I have an understanding question when the data tables / data sources is self developed and no standard data sources are used.
I have one data table (view) with primary keys and key figures:
Primary key:
ccar - credit control area.
compc - company code.
cust - customer.
salorg - sales organization.
salch - sales channel.
saldiv - sales division.
profc - profit center.
busseg - business segment.
busunt - business unit.
Key figures:
turn over
payments
open items
etc.
Those data sets are uploaded to data warehouse.
Now my question is, with each data set it should be possible to analyze with BEx Analyzer, for example
payments by customer.
payments by company code.
open items by customer and company code.
open items by credit control area.
One data set is available for the whole primary key combination (from fields ccar up to busunt).
Is my understandig correct?
Thank you in advance!!!

yes i guess so...., you can have reports based on turover per customers or turover per sale org,... like wise for others....

Thanks!
The report requirements are do be able to analyze for any kind of combination for the mentioned fields in the primary key.
That means the fields in primary key would be mapped to corresponding InfoObjects.
And then it should be possible to do analysis for all InfoObjects (single InfoObject or combination of them) and key figures (like I mentioned in my first posting for example).

Image in data tables

Hello,
Maybe some body can help me here. I have a data table and the headers are links where I can sorted the data I have the sort working but what I like to do is besides the column header link inser a image like an arrow pointing up for sort ascending and pointing down for descending but I'm having problems I try DIV to hide and show the image but that does no work any suggestions
Thanks

Use the 'rendered' attribute.
<h:graphicImage value="up.gif" rendered="#{!myBean.sortAscending}" />
<h:graphicImage value="down.gif" rendered="#{myBean.sortAscending}" />

Adding custom column to a Data Table (bound to database table)

Hello,
I've added an additional "Output Text" column to an existing "Data Table" component, which is pulling a database table and rendering it. It's actually called "OutputText5". What I want to do, is set the value of the "OutputText5" dynamically, depending on a Date comparison between the system date, and one of the currentRow field values, which is actually an Oracle Date data type. basically I'm trying to use the Date.after() comparison and put different content in there depending on true or false evaluation.
Seems simple enough .. but.. I'm trying to do this without using vim and JSP Beans (how I'd usually do this). I'm not experienced with JSF components and how this would be done using JSC - can I iterate over currentRow or something inside the "Page1.java" source? Is there an easy way to create dynamic value bindings like this in Data Table components in general? Maybe using expressions in "OutputText5" properties or something? I figure I should ask about doing this the easy way, before I spend lots of time and start teaching myself bad habbits.
I apologise in advance if this is a repeat post. I spent some time searching ,but came up empty handed.
Thanks in advance.

ETA for a JavaFX Data Table / Grid

Hi All,
Some of the posts in the forum seem to suggest that there is a JavaFX Data Table component in the works , any word on when we'll see something ? I'm looking for the following features ..
* Columns of different widths
* Columns that the user can resize at runtime
* Columns that the user can reorder at runtime
* Columns that can be filtered(removed) at runtime
* Customizable column headers
* Ability to use a custom cell rendered for any column to display data other than text
* Support for sorting the data by clicking on a column
* Pagination
* Runtime column selection
* Background row highlighting
Until a JavaFX data table arrives is it a recommended approach to use something like JXTable ?
Thanks
--gordon

Hi,
I think this is because of memory overflow.
You can create two screens for this, in on screen (Overview) screen, restrict the data selection.
In detail screen display the data.
With regards,

Extra non bound Row in a data table

We have the following question, which we believe is possible with creator:
In a data table, whose data source is a database table or Object List or EJB, is it possible to have the fisrt row (the row that comes after the column titles row) not bound to any data and used for another purpose? We want to use this row as a Query By Example (QBE) row, so that an application user may enter arbitrary search criteria into textbox columns in this row, column by column. When they click on a find button, data that meets the criteria is returned. We want something similar to the following html dislpay:
<table width="401" border="1">
<tr>
<th scope="col">Employee ID </th>
<th scope="col">First Name </th>
<th scope="col">Last Name </th>
</tr>
<tr>
<td>Text Box here for ID criteria </td>
<td>Text box here for First Name Criteria </td>
<td>Text Box here for last name criteria </td>
</tr>
<tr>
<td>101</td>
<td>David</td>
<td>Keen</td>
</tr>
<tr>
<td>102</td>
<td>Mary </td>
<td>Linda</td>
</tr>
<tr>
<td>103</td>
<td>Kevin</td>
<td>Lees</td>
</tr>
<tr>
<td>104</td>
<td>James </td>
<td>Bent</td>
</tr>
</table>
One possibility that we have considered is to dynamically create a table, using the following code. But this is not working as expected. First, the QBE row is not rendered( there is a message that says No Data Found). And second, the pagination controls do not display.
public HtmlPanelGrid getGridPanel1() {
//return gridPanel1;
Table dynamicTable = createTable();
gridPanel1.getChildren().add(dynamicTable);
return gridPanel1;
private Table createTable(){
Table table = new Table();
table.setId("table1");
table.setTitle("Dynamically Created Table");
table.setPaginateButton(true);
table.setPaginationControls(true);
// Create the Table Row group dynamically
createRowGroupQBE(table);
createRowGroupData(table);
return table;
private TableRowGroup createRowGroupQBE(Table tbe)
TableRowGroup rowGroup = new TableRowGroup();
rowGroup.setId("rowGroup1");
//rowGroup.setPaginated(false);
//rowGroup.setSourceVar("currentRow");
//rowGroup.setValueBinding("sourceData", getApplication());

Any ideas?

Here is a suggestion. I have not tried it myself
Add another method
    public void setSelected(RowKey rowkey, Object object) {
        if (rowKey != null) {
            tablePhaseListener.setSelected(rowKey, object);
    }

JSF 1.1 performance, especially UIData and Data Table

Hi,
Does anybody have any JSF 1.1 (Sun reference implementation) performance experiences to share? I am currently looking at the data table component and the use of UIData. Initial observations are an incredible amount of memory is churned during rendering the data table, with the following classes culprits:
java.util.HashMap$KeyIterator
javax.faces.component.UIComponentBase$ChildrenListIterator
java.util.AbstractList$Itr
char[]
java.util.ArrayList
javax.faces.component.UIComponentBase$FacetsMapKeySetIterator
javax.faces.component.UIComponentBase$FacetsMapKeySet
javax.faces.component.UIComponentBase$FacetsMapValues
javax.faces.component.UIComponentBase$FacetsAndChildrenIterator
To render 50 rows with 10 columns (each column only having a simple outputText component) I'm seeing 1.3Mb memory churned and 0.8 seconds processing time.
To rener 100 rows with same columns and components I'm seeing nearly 2Mb churned and 2 seconds processing time.
UIData.setRowIndex is a large culprit.
I'm really after finding out your experiences on JSF performance and its scalability.
Any help here is appreciated.
Thanks - JJ

Ajax4JSF and Tomahawk data table, strange behaviour

Hi,
I use the tomahawk data table to display a list of objects in my page with the following code snippet
<t:dataList value="#{userGallery.images}" var="image" layout="simple">
<a4j:region>
    <t:htmlTag value="div" styleClass="imageEntry">
      
      <h:outputLink value="gallery.faces">
        <f:param name="imageId" value="#{image.id}" />
        <t:div styleClass="imageWrapper image_#{image.id} #{image.inCart ? 'inCart' : ''}">
          <h:graphicImage value="#{ftp.apacheThumbnails}#{image.imageName}" alt="#{image.imageName}"/>
        </t:div>
      </h:outputLink>
      
      <t:htmlTag value="div" styleClass="textWrapper">
        <t:htmlTag value="div" styleClass="actions">
          <a4j:commandLink reRender="imageList,shoppingChart" styleClass="addToCart" value="+#{msg.detailCart}" action="#{shoppingCart.addImageToCart}" rendered="#{!image.inCart}">
            <f:setPropertyActionListener target="#{shoppingCart.chosenImageId}" value="#{image.id}" />
          </a4j:commandLink>
          <a4j:commandLink reRender="imageList,shoppingChart" styleClass="removeFromCart" value="-#{msg.detailCart}" action="#{shoppingCart.removeImageFromCart}" rendered="#{image.inCart}">
            <f:setPropertyActionListener target="#{shoppingCart.chosenImageId}" value="#{image.id}" />
          </a4j:commandLink>
        </t:htmlTag>
     </t:htmlTag>
   </t:htmlTag>
</a4j:region>
</t:dataList>I have marked the interesting part of the text.
When i first access the page then everything is rendered as it should be.
When i now klick on the a4j:commandLink then i got the following result: (only the interesting snippet)
<div class="imageEntry">
<a href="gallery.faces?imageId=2"/>
<div class="imageWrapper image_2 inCart">
     ..... (output as it should be)
</div>
<div class="textWrapper">
     .... (output as it should be)
</div>
</div>So you see the link tag is closed to early, it should wrapp the complete <div class="imageWrapper> object.
Anybody know how to solve this?
