How can i set row level rendering in datatable JSF.
<h:dataTable styleClass="tablesub" border="0" value="#{historyQuestBean.answerMasterList[row].inputTextKeySet}" var="option">
<h:column>
<h:outputText value="#{option.sectionShortName}:"/>
</h:column>
<h:column>
<h:outputText value="#{option.type}:"/>
</h:column>
</h:dataTable>
I want to render only those rows who have status true.
How can I do this?
Easier and Simplest thing is to pass the list of values with status = true
In <h:datatable> you can give a style class within rowClasses say renderer and in that class specify a condition like display:#{option.status==true}?'block':'none'. This will evaluate the EL and accordingly place the style of that <tr\> to display or not.
Another option is to use <ui:repeat> instead of <h:datatable>, Here you can place rendered condition for the <tr>.

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>
...
I have a List in my backing bean. I want to present it in a table. I want table to have two rows - on left side, values from the list, and on the right side inputBoxes. It's the easy part. Here's my code:
<div class="table">
<h:dataTable id="korekty" styleClass="table table-hover"
value="#{searchBean.listX}" var="v">
<h:column>
<f:facet name="header">XXX</f:facet>
#{v.string}
</h:column>
<h:column>
<f:facet name="header">YYY</f:facet>
<h:inputText styleClass="form-control">
</h:inputText>
</h:column>
</h:dataTable>
</div>
The hard part of my problem is : in those inputtext user might put some numbers. Then after hitting SUBMIT button I want to create a list/map/whatever of inputed values. How can I do that? Thanks for help
First of all, prepare an array, or a list, containing placeholders for the given data alongside the list you've got:
List<String> initialData = ...;//initial data of n size
String[] submittedData = new String[initialData.size()];//array of the same size
Then, bind the <h:dataTable> component to the view to get access to the current row index of the iteration. This way you can finish your job by binding value of input elements to the corresponding objects in the array/list:
<h:dataTable binding="#{table}" ... >
<h:column>
<f:facet name="header">YYY</f:facet>
<h:inputText value="#{searchBean.submittedData[table.rowIndex]}" ... />
</h:column>
</h:dataTable>
I'd like to be able to click the headers in a table to sort the respective columns. When I try to do this with a h:commandLink and pass the column name as a parameter I get an error saying that the commandLink needs to be ended with > or />, which I do. Example:
<h:column>
<f:facet name="header">
<h:commandLink
value="name"
actionListener="#{albumListBean.sort("album_name")}">
</h:commandLink>
</f:facet>
<h:outputText value="#{item.name}" styleClass="tableItem" />
</h:column>
I get the same result using f:ajax or p:commandLink. If I remove the parameter however, I get no error (but of course the sorting doesn't work either).
Is it not allowed to pass a parameter this way inside the f:facet?
The strings inside EL expressions must be expressed inside simple cotes :
<h:commandLink
value="name"
actionListener="#{albumListBean.sort('album_name')}">
</h:commandLink>
I am using JSF 2.0. When I am trying to use a variable in the 'id' attribute of the h:dataTable its not taking that variable value.
I have h:dataTable inside ui:repeat with id values as index of ui:repeat as mentioned below.
<ui:repeat var="planMap" value="#{planAccountMap.entrySet().toArray()}" varStatus="planMapStatus">
<h:dataTable id="planTable#{planMapStatus.index}" value="#{planMap.value}" var="accountList">
Does any one know whether we can have dynamic id generated for h:dataTable in loop?
I have a Java script which is making use of table id, but as I am not able to have the unique id for each table in the loop, its breaking.
Any component inside of a repeatable component will always have a dynamic client id. You cannot do this.
Perhaps instead you can assign a unique style class to the dataTable component and use a jQuery selector to return an array of all the dataTable objects in the ui:repeat.
jQuery('.SomeClass');
I do some thing very similar to you. i have a UI:repeat inside a datatable column. tbh, if you check in fire bug, your datatable id would be unique as you put it inside a ui:repaet.
planMap:0:yourdatatableID
This problem can be solve by using datatable inside datatable. Second datatable is kept inside the column of the first datatable as below.
<h:dataTable id="outerTable" value="#{planAccountMap.entrySet().toArray()}" var="planMap" width="100%">
<h:column>
<h:dataTable id="planTable" value="#{planMap.value}" var="accountList"
headerClass="tablehead"
rowClasses="'',altrowcoloropt1"
first="0">
<h:column>
<f:facet name="header">
<h:outputText value="Date" />
</f:facet>
<h:outputText value="#{accountList.date}"/>
</h:column>
<h:column>
<f:facet name="header" >
<h:outputText value="Account Name" />
</f:facet>
<h:outputText value="#{accountList.accountName}"/>
</h:column>
</h:dataTable>
</h:column>
</h:dataTable>
By this you would get unique id as outerTable:0:planTable, outerTable:1:planTable.This even extend the unique id to each element in datatable as outerTable:1:planTable:1:columnid , outerTable:0:planTable:0:columnid
What will happen if the EL expression like #{bean.list} is null. I've a nested datatable and the "value" of dataTable evaluates to null. In below example if issuerList is null, outer table footer is displayed but not the inner table. How does #{Issuer.issue} is handled considering "Issuer" is null !!!
Ex:
<h:datatable value="#{bean.issuerList}" var="issuer" >
..
<h:datatable value="#{issuer.issueList}" var="issue" >
....
....
<f:facet name="footer">
This is inner footer
</f:facet>
</h:datatable>
<f:facet name="footer" >
This is outer footer
</f:facet>
</h:datatable>
If the #{bean.issuerList} is null then there are simply no rows to render. Since the nested datatable (and its footer) is part of a row, it's also never rendered. You would need at least one row to get the nested datatable (and its footer) to render. The footer of the outer datatable is not part of any row, so it's always rendered.
