I need create an primefaces Datatable with InputText into cells and get de information edited in the inputText
I create the datatable with the next code:
<p:dataTable value="#{busquedaArticulo.attr}" var="rowName" styleClass="table table-bordered table-stripped" rowIndexVar="rowIdx">
<p:column headerText="" styleClass="ui-widget-header">
<h:outputText value="#{rowName}"/>
</p:column>
<p:columns value="#{busquedaArticulo.siz}" var="columnName" headerText="#{columnName}" columnIndexVar="colIdx">
<h:inputText id="siz" value="#" styleClass="form-control" />
</p:columns>
</p:dataTable>
I suggest you to use editable row. you can show value of each entry if it has been set by user or has a default value or leave it empty or "not set" if it's not set.
user can click on pencil icon and edit value of each row. once row has been edited you can get new value in your backing bean.
look at this: http://www.primefaces.org/showcase/ui/data/datatable/edit.xhtml
hope it was useful :)

I am using Primefaces 5.1 in my page I use dataTable inside another dataTable.In add button press add new bean for salList and check salList not null to rendered header column.But sal column not rendered.
<p:dataTable id="mainTable" value="#{employee.employeeList}" var="emp" ..>
<p:columnGroup type="header">
<p:row >
<p:column headerText="Name"/>
</p:column headerText="value" **rendered="#{emp.salList ne null and not empty emp.salList}**/>
....
<p:column>
<f:facet name="header"><p:commandButton value="add button" action="#{employee.addButton}" update="mainTable"/>
</f:facet>
</p:column>
</p:row>
</p:columnGroup>
<p:column>
<p:dataTable value="#{emp.salList}" var="sp">
<p:column></p:column>
..
</p:dataTable>
</p:column>
</p:dataTable>
My doubt is when I press add button to add new list salList bean and it add new bean and show component in inside dataTable.But in header column salary column is not rendered i.e header column not updated it will not rendered the specify header column.
I have a search screen that displays data grouped together based on the search value. This is how the display is accomplished. I have a p:accordionpanel that gets dynamically populated from the back end bean. I have a p:datatable with in the p:accordianpanel. There can be more than one accordion panel that gets displayed each containing a datatable. The display works as expected.
Problem: I have implemented filter and multiple selection of rows on the datatables. If there are more than 1 datatable that gets populated, the filter and search only works on the last datatable. The selection and filteredValue attributes of the p:datatable are bound to separate objects. If I click on any of the "Select All" boxes, the rows from the last table gets selected. I would expect the rows on the table that's associated with the "Select All" check box to be selected.
Here's the accordion / datatable:
<p:accordionPanel multiple="true"
value="#{basicSearchResultsVO.sortedMessages}" var="sortedMessages">
<p:tab title="#{sortedEdiMessages.key}">
<p:dataTable id="dataTable"
emptyMessage="No Data found with searched criteria"
filteredValue="#{sortedMessages.value.filteredMessages}"
rowKey="#{message.archiveSequenceI}"
rows="10"
selection="#{sortedMessages.value.selectedMessages}"
sortBy="#{message.msgDateTimeTs}" sortOrder="descending"
value="#{sortedMessages.value.messages}" var="message"
widgetVar="messagesTable">
<f:facet name="header">
<p:outputPanel style="text-align: right;margin:3px;">
<h:outputText value="Search all fields:"/>
<p:inputText id="globalFilter" onkeyup="PF('messagesTable').filter()" style="width:150px;" placeholder="Enter keyword"/>
</p:outputPanel>
</f:facet>
...
</p:dataTable>
</p:tab>
...
</p:accordionPanel>
I am not sure what I am missing. Would appreciate your assistance and feed back.
OK. I found the issue with the code. Had to make the widgetVar attribute on the datatable unique for the filter / multi select to work correctly on each datatable. Here's the modified code. The only change is to the widgetVar attribute of the p:datatable and the onkeyup attribute of p:inputText bound to a unique value provided by the backend bean.
<p:accordionPanel multiple="true"
value="#{basicSearchResultsVO.sortedMessages}" var="sortedMessages">
<p:tab title="#{sortedEdiMessages.key}">
<p:dataTable id="dataTable"
emptyMessage="No Data found with searched criteria"
filteredValue="#{sortedMessages.value.filteredMessages}"
rowKey="#{message.archiveSequenceI}"
rows="10"
selection="#{sortedMessages.value.selectedMessages}"
sortBy="#{message.msgDateTimeTs}" sortOrder="descending"
value="#{sortedMessages.value.messages}" var="message"
widgetVar="#{sortedEdiMessages.key}">
<f:facet name="header">
<p:outputPanel style="text-align: right;margin:3px;">
<h:outputText value="Search all fields:"/>
<p:inputText id="globalFilter" onkeyup="PF('#{sortedEdiMessages.key}').filter()" style="width:150px;" placeholder="Enter keyword"/>
</p:outputPanel>
</f:facet>
...
</p:dataTable>
</p:tab>
...
</p:accordionPanel>
I have a primefaces datatable and inside the primefaces datatable, I have a column, which contains the . The issue is,I have set the default value for the as false. When I click/check the , its still retrieving the value as false. I tried it multiple times but not sure why its returning false. Please find the sample code below.
<p:dataTable id="review-table" var="item" value="#{demandBean.filterVOList}">
<p:column id="SelectallID" style="text-align: left; width:40px;" rendered="#{demandBean.screeRenderVo.selectAllRenderer}">
<f:facet name="header" >
<h:outputText id="selectId" value="#{demandBean.dmdScreenLabelVO.selectAll}" />
<div></div>
<h:selectBooleanCheckbox id="checkbox1" value="Select All" onclick="checkAll(this)"/>
</f:facet>
<h:selectBooleanCheckbox id="checkbox2" value="#{item.selected}"/>
</p:column>
Im getting the value as false, when I check the and click on the save button. I have written an Action listerner, below is the code corresponding to the actionListener
public void saveData(ActionEvent event)
{
System.out.println("Entering the Save :");
selected = isSelected();
System.out.println("value of Selected"+selected);
}
I have tried debugging the code as well, but not sure why the value for is getting displayed as false. Please Assist. Thanks in Advance
You seem to be binding the value of all checkboxes in the column to the one and same bean property. This way the value will ultimately end up to be the one of the last row in the column.
This is not how it's supposed to be used.
You basically need to bind the value of the checkbox to the property of the currently iterated row object (the one behind the var attribute of the datatable).
<p:dataTable value="#{bean.items}" var="item">
<p:column>
<p:selectBooleanCheckbox value="#{item.selected}" />
Alternatively, you could use the <p:column selectionMode="multiple" /> to use builtin multiple selection support of the PrimeFaces datatable (see also the showcase example).
<p:dataTable value="#{bean.items}" var="item" rowKey="#{item.id}" selection="#{bean.selectedItems}">
<p:column selectionMode="multiple" />
I use primefaces 3.0.1 and I have a problem with my datatable.
I use my datatable with the instant row selection. That works very well.
But I wish use in the same time the checkbox selection (for exemple, for select some rows and delete the selected rows)
And when I use the
<p:column selectionMode="multiple" />
the checkbox are display, but I can't check any checkbox....
Anyone have a solution ?
Thanks.
P.S. :
my code
<p:dataTable id="rows" var="row" value="#{myBean.row}" selection="#{myBean.selectedRow}" selectionMode="single">
<p:ajax event="rowSelect" listener="#{myBean.onRowSelect}" update="#form"/>
<p:column selectionMode="multiple" style="width:18px" />
<p:column>
<h:outputText value="#{row.subject}" />
</p:column>
</p:dataTable>
Checkboxes are to be used for multiple row selection, but you've still declared your <p:dataTable> for single row selection. Remove selectionMode="single" from the <p:dataTable> and make sure that the #{myBean.selectedRow} is changed to be an array instead.
E.g.
<p:dataTable ... selection="#{myBean.selectedRows}">
with
private Row[] selectedRows;
I need to add a row to my datatable on click of a button - "Add Employee".
The datatable shows the records corresponding to a fixed list of Employees in the bean.
What I am doing is, on click of the "Add Employee" button , I am adding an empty record of Employee to the empList.
Is there any better way to do this?
Thanks.
Either you open a dialog or a popup when clicking the add button. Then fill in the required fields (attached to a employee object. And when saving/submit you add that object to your list of employee objects. And rerender the datatable.
Or you can initially add an empty emploee object to your list. Showing it in the datatable with inputfields. On add, you add the new employee to the list and rerender the list.
list_Recs is list of records and shown in the data table.
<p:dataTable id="myTable" value="#{myBean.list_Recs}" selectionMode="single" var="myTableVar" selection="#{myBean.currentRec}">
<p:ajax event="rowSelect" listener="#{myBean.handleRowSelect}" update=":myForm:myPanel"/>
<p:column>
<f:facet name="header">
<h:outputLabel value="Field 1" />
</f:facet>
<h:outputLabel value="#{myTableVar.Field1}"/>
</p:column>
<p:column>
<f:facet name="header">
<h:outputLabel value="Field 2" />
</f:facet>
<h:outputLabel value="#{myTableVar.Field2}" />
</p:column>
<f:facet name="footer">
<p:commandButton value="New" action="#{myBean.prepareForInsert}" update=":myForm:myPanel"/>
</f:facet>
</p:dataTable>
<h:panelGrid id="myPanel" columns="2" >
<h:outputLabel value="Field 1"/>
<p:inputText id="fld1" value="#{myBean.newRec.field1}" />
<h:outputLabel value="Field 2"/>
<p:inputText id="fld2" value="#{myBean.newRec.field2}" />
<p:commandButton action="#{myBean.createAction}" value="Submit" update="myGrowl myTable" />
</h:panelGrid>
When New button is clicked, create an emty instance of newRec in prepareForInsert routine of myBean. So that myPanel is filled with blanks in the fields. On Submit, add the newRec to
list_Recs and the new record is diplayed in the data table because of the update on myTable.
Hope this helps.
A different option would be to show an empty employee in the footer facet of your datatable and add it to your list if the user clicks the add button. With this you can ensure that only correctly filled employee objects/entities are added to your list.
