With richfaces, how can I get my h:outputLabel and rich:combobox components to display directly adjacent to each other on the same line?
Here are the two approaches I've tried.
#1 rich:Layout
I first tried using rich:layout & rich:layoutPanel, but the components appear on separate lines. Here's the code:
<rich:layout>
<rich:layoutPanel position="left" width="100%">
<h:outputLabel for="timeSpanUnitsCombo2" value="Time Span " />
<rich:comboBox id="timeSpanUnitsCombo2" value="#{bean.timeSpanUnitsLabel}" enableManualInput="false">
<f:selectItems value="#{bean.timeSpanUnitsList}" />
</rich:comboBox>
</rich:layoutPanel>
</rich:layout>
And here's the rendered output:
#2 h:panelGrid
Next I tried using a h:panelGrid, but again no success - the components are evenly spaced over the available area, instead of being directly adjacent and left-aligned as I intended. Here's the code:
<h:panelGrid columns="2">
<h:outputLabel for="timeSpanUnitsCombo3" value="Time Span " />
<rich:comboBox id="timeSpanUnitsCombo3" value="#{bean.timeSpanUnitsLabel}" enableManualInput="false">
<f:selectItems value="#{bean.timeSpanUnitsList}" />
</rich:comboBox>
</h:panelGrid>
And here's the rendered output:
Component layout with richfaces is proving to be thoroughly frustrating. I'll give second prize to anyone who has some good references on layout with richfaces. :)
This can be done by many ways. One of them is to use fragment
<s:fragment>
<h:outputText value="Time Span" />
<rich:comboBox id="timeSpanUnitsCombo2" value="#{bean.timeSpanUnitsLabel}" enableManualInput="false">
<f:selectItems value="#{bean.timeSpanUnitsList}" />
</rich:comboBox>
</s:fragment>
Or you can use a div instead of fragment. <div> your code...</div>
If you are using seam, you can wrap it in <s:decorate> and use <s:label>
From Seam in Action
....<s:label> and <s:message>. The benefit of using the Seam tags is
that they are automatically correlated with the adjacent input component, a feature
of <s:decorate>

I want to develope a JSF composite component using PrimeFaces library.
Basically I want to update my composite component. I have read some SO questions about it (JSF updating a composite component or JSF Updating Composite Component (Primefaces)). But in this case I only want to update certain parts of the component.
Here is an example. My component should be a label/message/value-part of a <p:panelGrid /> to get rid of all the noise of the <p:column/>-tags.
<composite:interface>
<composite:attribute name="label" required="true" />
<composite:attribute name="value" required="true" />
</composite:interface>
<composite:implementation>
<p:column>
<!-- label -->
<p:outputLabel value="#{cc.attrs.label}" for="id_inputtext"/>
</p:column>
<p:column>
<!-- message -->
<p:message for="id_inputtext" />
</p:column>
<p:column>
<!-- inputtext -->
<p:inputText id="id_inputtext" value="#{cc.attrs.value}"/>
</p:column>
</composite:implementation>
To use this composite component I can simply put it in a panelgrid like so.
<p:panelGrid>
<p:row>
<mycomponent:columnSet id="c1" label="label" value="hello world"/>
<mycomponent:columnSet id="c2" label="label2" value="hello world2"/>
</p:row>
<p:row>
<mycomponent:columnSet id="c3" label="label3" value="hello world3"/>
<mycomponent:columnSet id="c4" label="label4" value="#{bean.someValue}"/>
</p:row>
</p:panelGrid>
In this case I can not surround the content of the component with an HTML container element like <div/> or <span/> like it is described in the above links. That would result in weird HTML because it would be within the generated table.
What I want to do in the example above is to update the <p:outputLabel/>, the <p:message/> and the <p:inputText/> from outside of the component. In a perfect world I want to update these three components independently from each other (but I guess that is even more complicated than updating all at once).
What I currently do to get this to work is kind of cheating. I create a <composite:attribute name="id" /> and give the three components fixed IDs based on a convention using the composite component id. That works but is pretty poor because using the composite component, one needs to know the inner implementation of the it.
Does anyone have an idea to solve this requirement in a nicer way?
<composite:interface>
<composite:attribute name="id" required="true" />
</composite:interface>
<composite:implementation>
<p:column>
<!-- label -->
<p:outputLabel id="#{cc.attrs.id}_label"/>
</p:column>
<p:column>
<!-- message -->
<p:message id="#{cc.attrs.id}_message" />
</p:column>
<p:column>
<!-- inputtext -->
<p:inputText id="#{cc.attrs.id}_value"/>
</p:column>
</composite:implementation>
EDIT
Thanks for the quick response in the comments.
As to the tag files: Indeed, I must admit that I avoided dealing with tag files because composite components are so much easier to handle, my bad.
Anyway, I just read some stuff, made a quick-and-dirty prototype, but came to the conclusion that (although it might be a good and proper way to use tag files in this label/message/input-situation) I have the same issue as with the composite component: To update the components inside the tag file I need to know the inner implementation of it (that is the same as described in my workaround).
I want to update the composite component/tag file from outside with a «single handle» and treat it as a black box.
If I could wish for a feature I want something to say «do the update» on the composite component/tag file. And within the composite component/tag file I can define which components should be updated if «do the update» is triggered. Something like three separate <div id="#{cc.clientId}"/> surrounding every component I want to update (which obviously is not possible like that).
Because I guess that this is nearly impossible, I would also be happy with a way to update a composite component/tag file as a whole, meaning to update every component within the black box.
I'm using RichFaces with JSF to develop a simple app. One page of this app contains several collapsiblePanel elements. Some of the collapsiblePanel elements are nested, but never more than a second layer.
I would like to provide links or buttons on the page to expand all and collapse all collapsiblePanel elements on the page. How can I do that?
The elements currently use the switchType="client" attribute to let the client handle the expanding and collapsing. I suspect that using a type of ajax instead may help, but I'm not sure nor do I know how I would take advantage of it.
Update: My question may be easier to understand if I include an example of what I'm trying to do:
<h:form>
<a4j:commandButton actionListener="#{bean.setDefaultExpanded(true)}"
render="reportPanel" value="Expand all" />
<a4j:commandButton actionListener="#{bean.setDefaultExpanded(false)}"
render="reportPanel" value="Collapse all" />
<h:panelGrid id="reportPanel">
<ui:repeat var="account" value="#{bean.results.entrySet().toArray()}">
<rich:collapsiblePanel expanded="#{bean.defaultExpanded}">
<ui:repeat var="chargeGroup" value="#{account.value.entrySet().toArray()}">
<rich:collapsiblePanel expanded="#{bean.defaultExpanded}">
<h:outputText value="content: #{chargeGroup.value}" />
</rich:collapsiblePanel>
</ui:repeat>
</rich:collapsiblePanel>
</ui:repeat>
</h:panelGrid>
</h:form>
The <rich:collapsiblePanel> has the expanded attribute, you can bind it to bean property and control the expansion from there. Something like this
<rich:collapsiblePanel id="panel1" expanded="#{bean.expanded}" …>
<a4j:commandButton actionListener="#{bean.togglePanels()}"
… render="panel1, panel2, …"/>
The switchType controls where the content is pulled from, not how you expand/collapse the panel.
I had the same problem when click individual panels and then expand/collapse all. This work for me (richfaces 4.2.3):
<h:commandButton immediate="true" action="#{controllerBean.toggleMin}" value="collapse all" >
<a4j:ajax render="panel1 panel2"></a4j:ajax>
</h:commandButton>
<h:commandButton immediate="true" action="#{controllerBean.toggleMax}" value="expand all">
<a4j:ajax render="panel1 panel2"></a4j:ajax>
</h:commandButton>
...
<rich:collapsiblePanel id="panel1" immediate="true" expanded="#{modelBean.expanded}" header="Title text" switchType="client">
...
</rich:collapsiblePanel>
...
The natural behaviour for a label attached to a checkbox button is to change the state of the button when it (the label) is clicked.
This works in JSF and Richfaces.
Is there a way to make it work in Primefaces(3.5) without involving javascript ?
Is this a bug ?
<p:outputLabel for="checkbox" value="Select it:" />
<p:selectBooleanCheckbox id="checkbox" label="My label" value="#{bean.value}" />
It doesn't work out-of-the-box in plain JSF but in PrimeFaces the itemLabel attribute should do it:
<p:selectBooleanCheckbox id="checkbox" itemLabel="My label" ... />
This bug has been fixed since PrimeFaces 4, so you can use p:outputLabel with recent versions of PrimeFaces. Good thing of the p:outputLabel is that it allows you to add body content to it. So you can add images, icons, a link to terms and conditions, etc.
<p:selectBooleanCheckbox value="#{bean.value}"/>
<p:outputLabel for="#previous">
Label to <strong>click</strong>
</p:outputLabel>
I have some list of elements, that generates my <h:selectOneRadio> items:
<h:selectOneRadio id="list#{cand.id}" value="#{mybean.value}" layout="pageDirection">
<c:forEach items="#{mybean.list}" var="c">
<f:selectItem id="first#{c.id}" itemlabel="#{c.surname}" itemValue="#{c.name}" />
</c:forEach>
</h:selectOneRadio>
I want next each element display <h:outputText> with value #{c.id}, so that at each row will be my radioButton element and next it some textbox. How can I do it ?
I tried something like that:
<h:selectOneRadio id="candidates1#{cand.id}" value="#{candidates.selectedCandidate1}" layout="pageDirection">
<c:forEach items="#{candidates.c1}" var="cand">
<td>
<f:selectItem id="first#{cand.id}" itemlabel="#{cand.surname}" itemValue="#{cand.name}">
<h:outputText id="c1ShortName#{cand.id}" value="#{cand.id}" />
</f:selectItem>
</td>
<td>
<h:outputText id="c1ShortName#{cand.id}" value="#{cand.id}" />
</td>
</c:forEach>
</h:selectOneRadio>
But it deisplays all radioButtons after last outputText.
I want something like the below screenshot. When right part is for example IDs, then it can be encrypted and decrypted.
Just put it in the item label.
itemlabel="#{c.id} #{c.surname}"
Or the other way round, you was not clear on that.
itemlabel="#{c.surname} #{c.id}"
You can if necessary use HTML like so, you should only beware of XSS attack hole in the surname.
itemlabel="#{c.surname} <strong>#{c.id}<strong>" itemEscaped="false"
Or, if you actually want to have them outside the generated <label>, then use a 3rd party component library. This is namely not supported by <h:selectOneRadio>. For example, Tomahawk's <t:selectOneRadio> has a layout="spread" attribute for that.

<h:selectOneRadio> renders table element, how to avoid this?
Unrelated to the concrete problem, you don't need that <c:forEach>. That's plain clumsy. Just use <f:selectItems var>. This is new since JSF 2.0, perhaps you were focusing too much on ancient JSF 1.x targeted resources.
<h:selectOneRadio ...>
<f:selectItems value="#{mybean.list}" var="c"
itemlabel="#{c.id} #{c.surname}" itemValue="#{c.name}" />
</h:selectOneRadio>

i want to customize selectItems
to display an image conditionally beside each checkbox
so first i tried to display the image for all checkboxes
but it gets displayed only once, here's what i tried:
<h:selectManyCheckbox value="#{myBean.checkboxesArry}" layout="pageDirection">
<f:selectItems value="#{myBean.mapOfCheckBoxes}" var="entry">
<label>
<ice:graphicImage url="/resources/images/myImage.bmp"/>
<b>#{entry.value}</b>
</label>
</f:selectItems>
</h:selectManyCheckbox>
please advise how to accomplish that ?
You cannot nest UI compnents in <f:selectItems> that way. I however see that you're using ICEfaces, you should then be able to use <ice:selectManyCheckbox layout="spread"> in combination with <ice:checkbox> instead.
<ice:selectManyCheckbox id="foo" value="#{myBean.checkboxesArry}" layout="spread">
<f:selectItems value="#{myBean.mapOfCheckBoxes}" />
</ice:selectManyCheckbox>
<c:forEach items="#{myBean.mapOfCheckBoxes}" var="entry" varStatus="loop">
<ice:checkbox for="foo" index="#{loop.index}" />
<ice:graphicImage url="/resources/images/myImage.bmp" />
<b>#{entry.value}</b>
</c:forEach>
(untested as I don't use ICEfaces, but the above construct works for Tomahawk, from which ICEfaces has basically copied the implementation; you can also use <ui:repeat> but it only supports Map since JSF 2.1)
