Related to the question Display formatted decimal numbers in Primefaces 4, how can I display - in a PrimeFaces datatable - a number masked like this:
1.987.654,32
The original data, which are read from a float column in SQLServer database table, is (e.g.):
1987654.32
I've tried the code below, but no success:
<p:column sortBy="#{item.value}" filterBy="#{item.value}">
<f:facet name="header">
<h:outputText value="#{epoBundle.ListUpbTitle_value}"/>
</f:facet>
<h:outputText value="#{item.value}">
<f:convertNumber pattern="#0.000" locale="pt_BR"/>
</h:outputText>
</p:column>
Thanks in advance.
The correct pattern for the <f:convertNumber .../> you want is: ###,###.000. You can read more about decimal formatting here: http://docs.oracle.com/javase/tutorial/i18n/format/decimalFormat.html
Bonus: for different masks, you can use other locales: https://stackoverflow.com/a/11836387/1362049

I've got a dynamic dataTable and would like to display different filter types depending on the column but it seems that I can only use one object within a filter facet at a time. If I try to use multiple input types I get a
java.lang.ClassCastException: javax.faces.component.UIPanel cannot be cast to javax.faces.component.ValueHolder
My current (not working) code looks like this:
<f:facet name="filter">
<p:inputText onkeyup="PF('myTable').filter()" rendered="#{column.filterType=='TEXT'}" />
<p:selectOneMenu onchange="PF('myTable').filter()" rendered="#{column.filterType=='LIST'}">
<f:selectItems value="#{column.filterMap}" />
</p:selectOneMenu>
</f:facet>
The inputText and selectOneMenus are displayed correctly, but I can't filter my table because of the ClassCast Exception.
If I only use one of the input types, the filtering works as expected.
Is it possible to conditionally show different filter facets or input types within the facet?
The only "solution" I found, is to always use selectOneMenus and make them editable and look like inputTexts if the filter type is "TEXT"
<p:selectOneMenu onchange="PF('myTable').filter()" editable="#{column.filterType=='TEXT'}" styleClass="#{column.filterType}">
following your 2nd comment I tested this code and it works; The idea is that the filter depends on the column, so:
<p:column filterBy="#{column.attribute}" filterMatchMode="contains" rendered="#{column.filterType=='TEXT'}" >
<f:facet name="filter">
<p:inputText onkeyup="PF('myTable').filter()" />
</f:facet>
</p:column>
<p:column filterBy="#{column.attribute}" filterMatchMode="equals" rendered="#{column.filterType=='LIST'}">
<f:facet name="filter">
<p:selectOneMenu onchange="PF('myTable').filter()" >
<f:selectItems value="#{column.filterMap}" />
</p:selectOneMenu>
</f:facet>
</p:column>
you show and hide the column, not the filter.
NB : The filter mode of an inputText is contains AND for a List is Equals.
I am trying to make a common datatable using primefaces.
I want to check if the current column of datatable is of Date type. If it is a Date I want to add DatetimeConverter -
Here is my code -
<ui:component>
<p:dataTable id="#{tableId}" value="#{data}" var="row" styleClass="stdTable vertLines fndTable vertLinesRightBorder"
style="table-layout:fixed; border-color: #dddddd;">
<p:columns value="#{tableColumns}" var="column" sortBy="#{row[column.property]}">
<f:facet name="header">
#{column.header}
</f:facet>
#{row[column.property]}
</p:columns>
</p:dataTable>
</ui:component>
I am calling the above xhtml as follows-
<ui:include src="table.xhtml">
<mbcpos:param name="tableId" value="#{me.id}hTabel1" />
<mbcpos:param name="data" value="#{taskListBean.receivedOwnerTasks}" />
<mbcpos:param name="tableColumns"
value="#{me.columns}" />
</ui:include>
Can we identify the column datatype :
e.g., #{row[column.property]} equals Date
If the column is a date I want to format the date.
Your column model should be where you put the data type it holds and other data type presentation related things like masks, currency, alignment etc.
On the page, for each data type (according to your needs), inside the p:columns
you should do something like this:
<h:outputText rendered="#{column.dateType}" value="#{row[column.property]}">
<f:convertDateTime pattern="dd/MM/yyyy"/>
</h:outputText>
I have a h:dataTable. I would like to render a row conditionally as follows:
<h:dataTable value="#{myController.entities}" var="entity">
<h:column rendered="#{entity.selected}">
<f:facet name="header">
<h:outputText value="header" />
</f:facet>
<h:outputText value="#{entity.name}" />
</h:column>
</h:dataTable>
In my controller there is variable List <Entity> entities which has getters and setters.
Entity class contains two variables : boolean selected and String name with its getters and setters.
When #{entity.selected} is false, then the row is hidden. When #{entity.selected} is true, then the row is shown, but without header. When I do not use the rendered attribute on the column my header becomes visible.
This question is similar to p:column header facet is not shown when rendered attribute is used on p:column
But none of the solution given works for me and Iam not using primefaces.
Can somebody help me with this? Iam new to JSF and the mistake might be something silly and fix fairly easy, but please help me figure it out. Thanks.
Iam posting the outputs that I get when I tried the above code.
**Header**
name 0
name 1
name 2
name 3
name 4
This output shows the datatable using simply <h:column> without trying to render it conditionally. The header can be seen.
Now when I use conditional rendering:
name 1
name 3
In this output Iam trying to use conditional rendering <h:column rendered="#{entity.selected}">. As you can see that for "name 0", "name 3" and "name 5" the #{entity.selected} is false and hence its not rendering.
This is exactly what I need but only if the header shows up.
I want to render my row invisible where the #{entity.selected} value is false. Also show the column header. Can this be possible?
You need to put the rendered condition on the cell, not on the column.
<h:dataTable value="#{myController.entities}" var="entity">
<h:column>
<f:facet name="header">
<h:outputText value="header" />
</f:facet>
<h:outputText value="#{entity.name}" rendered="#{entity.selected}" />
</h:column>
</h:dataTable>
Or, if you've multiple components or plain text representing cell content, wrap it in a <h:panelGroup> or <ui:fragment>.
<h:dataTable value="#{myController.entities}" var="entity">
<h:column>
<f:facet name="header">
header
</f:facet>
<h:panelGroup rendered="#{entity.selected}">
Blah blah #{entity.name} blah blah
</h:panelGroup>
</h:column>
</h:dataTable>
(note: you don't necessarily need h:outputText over all place, see also Is it suggested to use h:outputText for everything?)
Apply if necessary the following CSS on the table to hide empty cells in case you've applied e.g. borders or bgcolors on table cells:
table {
empty-cells: hide;
}
A completely different alternative is to provide a new model which contains only the desired entities:
<h:dataTable value="#{myController.selectedEntities}" var="entity">
<h:column>
<f:facet name="header">
header
</f:facet>
#{entity.name}
</h:column>
</h:dataTable>
Instead of
...
<f:facet name="header">
<h:outputText value="header" />
</f:facet>
...
try simply
...
<f:facet name="header">Header</f:facet>
...
This question already has an answer here:
Displaying a number in 2 point decimal format in jsf
(1 answer)
Closed 5 years ago.
I have a database table with a float field and I want to display it through Primefaces.
I want to display the numbers formatted as (one thousand, for example): 1.000,00
I tried:
<p:column sortBy="#{item.value}" filterBy="#{item.value}">
<f:facet name="header">
<h:outputText value="#{epoBundle.ListUpbTitle_value}"/>
</f:facet>
<h:outputText value="#{item.value}"/>
<f:convertNumber pattern="#0.000" locale="pt_BR"/>
</p:column>
But got:
/WEB-INF/include/entity/upb/List.xhtml #80,55 Parent not an instance of ValueHolder: org.primefaces.component.column.Column#13ec99d0
Can someone help me?
Thanks in advance.
f:convertNumber must be inside h:outputText.
<h:outputText value="#{item.value}">
<f:convertNumber pattern="#0.000" locale="pt_BR"/>
</h:outputText>
I need to render the <p:commandButton> at last entry of the <p:datatable> only .
consider if p:datatable having n no.of rows means i have render the p:commandButton at nth row only.
I think that you better use <f:facet name="footer">
<f:facet name="footer">
<p:commandButton/>
</f:facet>
But if you really insist on last row...
Try the rowIndexVar, something like this :
<p:dataTable value="#{myBean.myList}" rowIndexVar="rowIndex" var="item">
<p:column>
<p:commandButton rendered="#{(rowIndex+1) eq myBean.myList.size()}"/>
</p:column>
</p:dataTable>
I don't know if I got the functional requirement right, but from what I understand you want to add a single commandButton at the bottom of the table, for that you might use the following inside datatable tags:
<f:facet name="footer">
<p:commandButton/>
</f:facet>
