I want to get selected row data from ice:datatable ? Here is me code , please give me your suggestion to get selected row data using rowselector.
Backingbean:
public void rowSelectionListener(RowSelectorEvent event) {
System.out.println(event.getRow());
}
jspx code:
<ice:rowSelector id="selected" selectionListener="#{inventoryList.rowSelectionListener}" multiple="false" selectedClass="tableRowSelected" mouseOverClass="tableRowMouseOver" />
<f:facet name="header">
<ice:outputText value="Stock #"/>
</f:facet>
<ice:outputText value="#{item.stock}"/>
</ice:column>
Now I am able to get row index, but I need to get selected row value. How can I do that?
You can get the desired row by binding the table(HtmlDataTable) in backing bean, and on action or some other event you can get the selected row by tableBinding.getRowData() returning the object from the list that was used in table.

i have p:selectOneMenu, all values are viewed correctly but just first on my list can be chosen for example, on my list i have e-mail addresses, i can choose everyone but mail is sending just on first of them on list. My JSF code:
<p:dataTable value="#{additionalOrdersBean.additionalOrdersList}"
var="additionalOrders" rowIndexVar="lp" id="myTable" editable="true>
<p:column>
<p:selectOneMenu id="recipient" value="#{additionalOrdersBean.mailTo}" converter="#{mailConverter}" required="true" requiredMessage="#{loc['fieldRequired']}">
<f:selectItems value="#{buildingBean.buildingList2}" var="mail" itemLabel="#{mail.mail1}" itemValue="#{mail.mail1}" />
<f:selectItems value="#{buildingBean.buildingList2}" var="mail" itemLabel="#{mail.mail2}" itemValue="#{mail.mail2}" />
<f:selectItems value="#{buildingBean.buildingList2}" var="mail" itemLabel="#{mail.mail3}" itemValue="#{mail.mail3}" />
</p:selectOneMenu>
<h:message for="recipient" style="color:red"/>
<h:commandButton value="#{loc['send']}" action="#{additionalOrdersBean.sendProtocol()}" onclick="sendProtocolDialog.hide()"/>
</p:column>
</p:dataTable>
My bean:
private String mail1;
private String mail2;
private String mail3;
public List<Building> getBuildingList2() {
buildingList2 = getBldRepo().findByLocationId(lid);
return buildingList2;
}
Can anyone know how to fix it? I wont to send e-mail on choosen address not just on first on my list. Thanks
You seem to expect that only the current row is submitted when you press the command button in the row. This is untrue. The command button submits the entire form. In your particular case, the form is wrapping the whole table and thus the dropdown in every single row is submitted.
However, the value attribute of all those dropdowns are bound to one and same bean property instead of to the currently iterated row.
The consequence is, for every single row, the currently selected value is set on the bean property, hereby everytime overriding the value set by the previous row until you end up with the selected value of the last row.
You've here basically a design mistake and a fundamental misunderstanding of how basic HTML forms work. You basically need to move the form to inside the table cell in order to submit only the data contained in the same cell to the server.
<p:dataTable ...>
<p:column>
<h:form>
...
</h:form>
</p:column>
</p:dataTable>
If that is design technically not an option (for example, because you've inputs in another cells of the same row, or outside the table which also need to be sent), then you'd need to bind the value attribute to the currently iterated row instead and pass exactly that row to the command button's action method:
<p:dataTable value="#{additionalOrdersBean.additionalOrdersList}" var="additionalOrders" ...>
<p:column>
<p:selectOneMenu value="#{additionalOrders.mailTo}" ...>
...
</p:selectOneMenu>
...
<h:commandButton value="#{loc['send']}" action="#{additionalOrdersBean.sendProtocol(additionalOrders)}" ... />
</p:column>
</p:dataTable>
It's by the way not self-documenting and quite confusing to have a plural in the var name. Wouldn't you rather call it additionalOrder? Or is the javabean/entity class representing a single additional order really named AdditionalOrders?
Unrelated to the concrete problem: doing business logic in getter methods is killing your application. Just don't do that. See also Why JSF calls getters multiple times.
I created a JSF table like this:
<c:dataTable value="#{myViewController.all}" id="myViewTable" var="T" selection="#{myOtherView.select}" selectionMode="single" update="otherView>
<c:column filterBy="#{T.name}" sortBy="#{T.name}">
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet> <h:outputText value="#{T.name}"/>
</c:column>
Suppose that I have two entries within this table, they are name = a, and name = b. The method in myOtherView.select is
#SelectEvent
public void setSelect(Object value) {
}
I debuged the value in setSelect method. When open the view first time, I selected the first row from the table and the value is indeed a. Then I presses the header of 'Name', and the entries showing in the table is b then a. And I selected the first row from the table, the value is still a. not b..... Anyone who knows why this happened?**
I have data table like below:
<p:dataTable id="transactionTableID" binding="#{transactionReportBean.dataTable}"
value="#{transactionReportBean.summarizedDateWiseTransactionList}"
var="transacVAR" rowKey="#{transacVAR.OID}" style="float:center;">
<p:column headerText="#{build.reportSelection}">
<p:selectOneMenu id="" value="#{transactionReportBean.summaryTxnReportSelected}" >
<f:selectItem itemLabel="-Select One-" itemValue="-Select One-"/>
<f:selectItem itemLabel="#{build.matchedreport}" itemValue="#{build.matchedreport}"/>
<f:selectItem itemLabel="#{build.carryforwardreport}" itemValue="#{build.carryforwardreport}"/>
<f:selectItem itemLabel="#{build.exceptionreport}" itemValue="#{build.exceptionreport}"/>
</p:selectOneMenu>
<p:commandButton update="#form" value="Generate" ajax="false"
actionListener="#{transactionReportBean.getReportSelected}" />
</p:column>
</p:dataTable>
And an action listener method like below:
public void getReportSelected(){
if(this.SummaryTxnReportSelected.equalsIgnoreCase("-Select One-")||this.SummaryTxnReportSelected.equalsIgnoreCase(null)){
this.message = AlgoMessageHandler.getMessage(AlgoMessageHandler.USER_MSG, "ERR0048");
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR,
this.getMessage(), AFTSConstants.BLANK_STRING));
} else {
this.selectedDtTxn= (TransactionsSummaryReportVO) dataTable.getRowData();
System.out.println("listener called "+this.getSummaryTxnReportSelected()+" Selected transaction ID "+selectedDtTxn.getExecutionID());
String reportname = generateJasperReport(this.getSummaryTxnReportSelected(),AFTSConstants.SUMMARY_TXN_REPORT,this.selectedDtTxn);
System.out.println("Report Name"+reportname);
this.summaryReportStored= AFTSConstants.SUMMARY_REPORT_STORED_PATH+reportname+".pdf";
System.out.println(this.summaryReportStored);
this.setRenderGenerateButton(false);
}
}
That method is about to generate report based on the dropdown item we are selecting. In my table I have 10 rows, each row contains one dropdown having 3 items. There is a "generate" button. After selection of dropdown items and clicking the "generate" button, for first 9 rows it doesn't give component IDs and for 10th row it's working.
Here the problem is not about generating report, the problem is JSF doesn't take different component IDs for each dropdown in each row. I tried id="reportID", but no success. I tried to give row key value of table rowKey="#{transacVAR.OID}" as id="#{transacVAR.OID}", but it throws an exception like "empty component id".
How am I supposed to solve this problem?
Your problem has nothing to do with component IDs. Your problem is caused because you're binding submitted values of all rows to one and same bean property. JSF processes the submitted values based on the order the input elements appear in the tree. So, JSF will call the very same setter method with the submitted value for every single row until the last row is reached. You end up with the value of the last row. If you have placed a breakpoint on the setter method, you'd have noticed that it's subsequently been called with different values from every individual row.
You need to bind the value to the currently iterated row object instead.
<p:selectOneMenu value="#{transacVAR.summaryTxnReportSelected}">
I want to get the selected row of my dataTable, directly if the user selects a row.
I have added
<p:dataTable id="dataTableID" var="row"
value="#{bean.value}"
rowKey="${row.id}"
selection="#{bean.selectedValue}" selectionMode="single">
It is just possible to get it after clicking on a button.
There are two ajax-events for instant row selection in primefaces dataTable. One for the selection and one for the unselection.
<p:dataTable ..>
<p:ajax event="rowSelect" listener="#{yourBean.someListener}"/>
...
</p:dataTable>
Now you can access the selected item (of class Foo) like this:
public void someListener(SelectEvent event) {
(Foo) event.getObject() // cast "Object" to "Foo"
}
For additional information take a look at the primefaces showcase first: http://www.primefaces.org/showcase/ui/datatableRowSelectionInstant.jsf
In a scrollable datatable, which displays a collection of objects , I have to add one manual row as first row. That row contains inputText, through which user can able to enter some values and while hitting enter, those values will save and displays in bottom rows. I couldnt able to add this manual row as first row. Below is the current code.
<rich:scrollableDataTable value="{resultList}" var="result">
<rich:column>
<f:facet name="header">Name</f:facet>
<h:outputText value="#{result.name}" />
</rich:column>
<rich:column>
<f:facet name="header">Category</f:facet>
<h:outputText value="#{result.category}" />
</rich:column>
</rich:scrollableDataTable>
The above code is for just displaying the values from the backend.
1) For that you have to use bind rich:scrollableDataTable with the instance of HtmlScrollableDataTable in the backing bean.
In backing bean, create instance of it with accessor methods & then you can initialize it accordingly by adding the inputText components. Add actionListeners to these input components & then in listeners, you can add these inputText values as outputText to the table again as rows accordingly.
2) Else you can use inputText rather then outputText & disabling the subsequent rows other then 1st, so only data may get displayed - preventing input.
<rich:scrollableDataTable value="{resultList}" var="result">
<rich:column>
<f:facet name="header">Name</f:facet>
<h:inputText value="#{result.name}" disabled ="#{!result.isFirstRow}"/>
</rich:column>
<rich:column>
<f:facet name="header">Category</f:facet>
<h:inputText value="#{result.category}" disabled ="#{!result.isFirstRow}"/>
</rich:column>
</rich:scrollableDataTable>
Backing Bean :
//---
public void initialize(){
resultList.add(new Result("", "", true)); // Setting 1st input row enabled
}
public void inputListener(ActionEvent event){
// appending object based on input to the resultList
resultList.add(new Result(inputName, inputValue, false));
// added a boolean field to identify rows added later & to make them enable/disable accordingly
}
//---
I am not familiar with Richfaces, but tried to achieve it, as I was doing it with IceFaces.
