Conditionally displaying JSF components
(3 answers)
Closed 2 years ago.
I am new to primefaces and JSF. I want to make selectBooleanCheckbox visible by depending on some Boolean value in my bean. But there is no visibility feature. And if I add a panel the design changes. So do you have any suggestions?
<p:selectBooleanCheckbox id="idCheckbox" value="#{bean.object.value}" itemLabel="{bean.object.value.label}" styleClass="width100Percent" disabled="{bean.infomode}">
You can add "rendered" attribute to control whether the component is displayed.
<p:selectBooleanCheckbox id="idCheckbox"
value="#{bean.object.value}"
itemLabel="#{bean.object.value.label}"
styleClass="width100Percent"
disabled="#{bean.infomode}"
rendered="#{bean.showIt}"

How to use <h:selectBooleanCheckbox> in <h:dataTable> or <ui:repeat> to select multiple items?
(3 answers)
Closed 5 years ago.
I have an <ui:repeat> in which I has a list of object , next to each of those object I need to have a checkbox ( to check this element).
I want to know how could I integrate those checkboxes inside the <ui:repeat> in order to have many rows and each rows needs to has the object.getName() and next to it I need to have the checkbox ?
If this is feasible, Please how could I obtain those checked objects in the backing bean ?
<ui:repeat var="myObject" varStatus="status"
value="#{Bean.getListObjects}">
<b>#{status.index+1} .</b>
<h:outputLabel value="#{myObject.name}" />
//need the checkbox here for example
</ui:repeat>
Just create a map with the object UID as the key and a boolean as the value. Then value-bind each checkbox to a map entry.
Assuming your names are unique, you could use them. So, in you bean create a Map<String,Boolean>, and initialize the map with each object.
You can use the map to in the checkbox value like value="#{bean.map[object.name]}".

I have A PrimeFaces wizard each tab contains InputText fields or SelectOneMenu menus ... how could I reset all fields and menus in all tabs on submit button ??
I'm using primefaces 5.3
thank you
PrimeFaces has a component for clientside resets
<p:commandButton value="Reset Tag" update="#form" process="#form" style="margin-right:20px;" >
<p:resetInput target="***idFromYourTag***" />
</p:commandButton>
If you need reset the backing bean values, you need to write a method.

How does rendered work? It hides h:form content completely and does not show it if expression.list is not empty.
<h:form id="stackForm" rendered="#{not empty expression.list}">
<p:orderList id="stack" value="#{expression.list}"...
...
It doesn't hide it - it doesn't render it at all, if rendered condition evaluates to false. In your case, if #{expression.list} is empty, form will not be rendered. Or, when rendered is translated to plain English, read it as Render the form if expression.list is not empty.

How does the 'binding' attribute work in JSF? When and how should it be used?

I have a datatable that reads registers from a database.
In the datatable I have a panelgroup that is populated by binding
My problem is that I can not pass a parameter. I want to pass a value from the datatable variable, in that case preg, on each row I want to know the value of the register read to populate the panelgroup.
If I display the value it works fine for each row: #{preg.idpreg}
<h:dataTable var="preg" value="#{Pregbacking.list(Pregbacking.idenq)}">
<h:column>
#{preg.idpreg}
<h:panelGroup binding="#{Pregbacking.dynamicDataTableGroup(preg.idpreg)}"/>
</h:column>
</h:dataTable>
Does anybody know how can I solve this?
That should work just find but I believe that you need to make sure you are using a modern servlet spec (v3 I think). Use the latest Glassfish or Tomcat app server.
