This is probably a CSS problem, but I cannot understand the reason by myself.
I often found some selectonemenus behaving like the one in picture:
The dropdown field is "covered".
Then I click it, select a value and... it starts displaying correctly.
I am using Cupertino theme.
If I analyze the generated source, here's what I find:
<div class="ui-helper-hidden-accessible">
<input id="carrello:formCarrello:j_idt165_focus" name="carrello:formCarrello:j_idt165_focus" type="text">
</div>
<label id="carrello:formCarrello:j_idt165_label" class="ui-selectonemenu-label ui-inputfield ui-corner-all" style="width: 0px;">
Seleziona...
</label>
The label has "width:0px;". If I remove it, the menu is displayed correctly.
Good but... I DID NOT add that attribute. Why is Primefaces adding it?
EDIT
The source of the first menu:
<p:selectOneMenu value="#{posController.rigaVendita.codiceIva}" effect="fade" converter="codiceIvaConverter">
<f:selectItem itemLabel="Seleziona..." itemValue="" />
<f:selectItems value="#{posController.codiciIva}" var="ci" itemLabel="#{ci.codice}" itemValue="#{ci}" />
</p:selectOneMenu>
The same problem in all browser.
It isn't a css compatibility issue, the fault is the "0px" width attribute!
Ok I finally found what caused the bug!
I had the same problem with selectOneMenu label.
It is because I used the default forward page navigation, that's why in some pages components were working and not in other pages.
Actually it's not working when the url is not matching the page.
Solution : concat view id with "?faces-redirect=true" in action attribute of commandLink or commandButton
This can help:
http://www.mkyong.com/jsf2/jsf-page-forward-vs-page-redirect/
http://www.mkyong.com/jsf2/implicit-navigation-in-jsf-2-0/
The same problem occurred with the PrimeFaces google map component <p:gmap> you need also to use redirection if you want to use it
( And there is another problem: if you are using a template you have to put
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script>in the template.xhtml, see (primefaces GMmap inside a dialog not rendering) )
EDIT
And apparently it's OK:
PrimeFaces does not support forward based navigations within an ajax request, you need to do redirect instead or set ajax to false.
http://primefaces.org/faq.html
I've just had the same problem. I guess it was a bug of primefaces. My solution is to override zero width of that element — just add this code into your CSS file:
.ui-selectonemenu-label{
width: 100%!important;
}
I had the same problem and the solution consists in over write the css of the selectOneMenu in this case, correspond to two selectors, that are the following:
.ui-selectonemenu .ui-selectonemenu-trigger{
width: auto !important;
padding-top: 0.4em;
}
.ui-selectonemenu{
padding-right: 0px !important;
}

Good Evening, i want to know how to insert space between JSF components that lies in same <div> without using <h:outputText value=" " /> i used it and in order to insert the desired space that i want i repeated these tag around 50 times! what are the alternative approaches to do that, these is the <div> :
<div
style="width: 100%; font-size: 20px; line-height: 30px; background-color: gray">
<h:outputText value="" />
<h:outputLabel value="Notifications ">
<h:graphicImage
value="/resources/images/lunapic_136698680056094_2.gif" />
</h:outputLabel>
/// insert space here
<h:outputLink id="lnk" value="#">
<h:outputText value="Welcome,Islam"></h:outputText>
</h:outputLink>
<p:tooltip for="lnk">
<p:graphicImage value="/resources/images/sofa.png" />
</p:tooltip>
</div>
This is normally to be achieved using CSS, e.g. via the margin property. CSS works on HTML and JSF is in the context of the current question merely a HTML code generator. You should ignore the JSF part in the question and concentrate on the JSF-generated HTML output in order to achieve the requirement. You can see it by rightclick, View Source in a webbrowser. If the HTML needs some altering, then change the JSF source code in such way that it generates exactly the desired HTML.
E.g.
<h:outputLabel value="Notifications" style="margin-bottom: 100px;">
(please note that using style is a poor practice; CSS should preferably be declared in a .css file which you import via <h:outputStylesheet> and reference via styleClass attribute)
Again, this all has nothing to do with JSF. JSF is in the context of this question merely a HTML code generator. If you're brand new to basic HTML/CSS and thus doesn't exactly understand what JSF is producing, then I strongly recommend to take a JSF-pause and learn those basics first.
Unrelated to the concrete problem, the <h:outputLabel> generates a HTML <label> element, but you don't seem to have any HTML input element associated with it. You're in essence abusing the label element for the wrong purpose. Understanding basic HTML and how to write semantic HTML and knowing what HTML output those JSF components exactly generate should push you far in the right direction. In this particular case, you should likely be using <h:outputText> instead.
To insert spaces between components in the same line, you can use img tag with a 1x1 clear image. (Note: this should be the last resort until other options exhausted, see discussion below)
<img width="100" height="10" src="/path-to/dot_clear.gif" />
e.g.
<img width="100" height="10" src="https://raw.githubusercontent.com/jonathanluo/jsf/master/images/dot_clear.gif" />
Enter desired width; for height any number between 1 to 10 will do.
By default, the unit of width and height is pixel

I am using <p:fileUpload> tag for file upload functionality. But I need to change the text box size which I am unable to.
<h:outputLabel id="attachment_label" value="Add Attachment(s)" styleClass="atf-label" />
<p:fileUpload value="" mode="simple" style="width:350px"/>
I tried to set the width in CSS, but it didn't have any effect.
I've done a bit of testing to see if this was possible. Primefaces translates the simple fileUpload as :
<input type="file" id="fileUploadForm:j_idt90" name="fileUploadForm:j_idt90" style="">
This is basicly the standard browser input field of the type file, meaning on chrome, firefox, ie... ect it will all look differently. Now in my locale the standard size of this box is 238px, and by increasing the width of the input type, I do see the box surrounding the upload to grow larger, but sadly the textbox and button don't follow.
If you want the fileupload to be different i would suggest looking at the advanced mode for the fileupload. You can see it at work on the primefaces showcase : http://www.primefaces.org/showcase/ui/fileUploadSingle.jsf
Edit: I forgot to test it in IE8 (Only have ie8 on this computer). In chrome the text is an output text, in firefox it is in an inputtext field that can't grow larger, but on IE8 if i add the width:
<p:fileUpload value="#{fileUploadBean.file}" mode="simple" style="width:500px;"/>
The inputbox does grow larger.
This is the big limitation in the file upload functionality for a long time.Primefaces FileUpload is not an exception to this scenario.So, there is no way to change the Width of the input text box. If you want more info and other options check this anwser :
Can we change <input type="file"> style?
Primefaces p:fileUpload text size increased by applying inputField styleClass.
style.css
.inputField {
width: 350px !important;
}
fileUpload.xhtml
<p:fileUpload id="imageId" mode="simple" styleClass="inputField"></p:fileUpload>
a newbie primefaces question:
When I create a simple primeface page, what should I put in order to have the text styled?
<h:body>
<!-- Ok, what I put here to have styled the following H1 and outputText? -->
<h1>Not styled h1</h1>
<h:outputText value="Not styled text." />
</h:body>
</html>
I am able to get styled text by placing it inside a <\p:panel>, but I find that a bit annoying to place everything in panels.
Use css to change it, it's the most elegant solution. You can create your own classes or override existing primefaces ones if you're sure you aren't going to use the original ones. Remember to add !important at the end of the attributes set.
.ui-panel
{
border: black solid 1px !important;
}
You can just follow this tutorial about how and where to add your css reference in order to make Primefaces styles overriden.
PrimeFaces's CommandButton allows to specify an icon:
<p:commandButton value="Press me" icon="redBall" ... />
However, I need to enable/disable the icon depending on a JSF managed bean property.
I tried
<p:commandButton value="Press me" icon="#{bean.iconClass}" ... />
This works for choosing different icons, but does not allow to disable the icon altogether (i.e. get the same rendering like without the icon= attribute). I can return an empty string in getIconClass(), but PrimeFaces will still render the extra <span> for the icon inside the button, and CSS styling causes this span to be visible with a default icon.
Is there a way to tell PrimeFaces "I want no icon at all" (other than taking out the icon= attribute altogether)?
I can think of 2 ways without duplicating the button.
Supply the icon as <f:attribute> which is conditionally added by <c:if>.
<p:commandButton ...>
<c:if test="#{not empty bean.icon}"><f:attribute name="icon" value="#{bean.icon}" /></c:if>
</p:commandButton>
Set a style class which hides the icon altogether and supply it conditionally.
.hideicon .ui-icon { display: none; }
.hideicon .ui-button-text { padding-left: 1em; }
with
<p:commandButton ... icon="#{bean.icon}" styleClass="#{empty bean.icon ? 'hideicon' : ''}" />
A lame workaround would be to have 2 commandbuttons. One with icon definition and one without. And then render the correct one.
I have a JSF page with a rich:dataTable where, in each row, I put h:commandLinks to lead to pages with the details of the row selected.
I wanted to make the whole row clickable, calling the action method when the user clicks anywhere in the row.
Is that possible without JavaScript?
And if JavaScript is the only way out, what would be the best way do it? Search for a commandLink and "click" it?
Thanks in advance!
I got the whole rows clickable with a bit of styling. I made the links inside the cells occupy the whole cell with display: block; for the links and padding:0 for the cell.
So, here is what you need to do. In the JSF page, set up rowClasses and the links in each cell:
<rich:dataTable value="#{myMB.listaElems}" var="elem" rowClasses="clickable">
<rich:column>
<h:commandLink action="#{myMB.preUpdate(elem)}" value="#{elem.item1}" />
</rich:column>
<rich:column>
<h:commandLink action="#{myMB.preUpdate(elem)}" value="#{elem.item2}" />
</rich:column>
</rich:datatable>
And in the CSS sheet:
tr.clickable td {
padding: 0;
}
tr.clickable td a {
display: block;
padding: 4px;
}
And that's it!
The only downside is that you need to repeat the link in each cell, but the HTTP flow remains simple, you don't need to change any component, and it will work for h:links or good old <a> html links -- a pretty acceptable tradeoff, I'd say. :)
The basic problem is that JSF (core) is tied to the HTML table element for query-result rendering via the dataTable component. Since a JSF dataTable renders as an HTML table, the result is limited to what can be managed in columns (no out-of-the-box row control that I have seen). The HTML/CSS way to do this is quite elegant but in order to accomplish this in JSF, I believe the UIComponent renderer for dataTable would need to be overridden to output this:
<div class="table">
<a href="#" class="row">
<span class="cell">Column-1-Value</span>
<span class="cell">Column-2-Value</span>
</a>
...
</div>
With CSS styles table row and cell representing display:table, display:table-row and display:table-cell; respectively. This makes the row completely clickable but it behaves as a proper table. I have not embarked on re-writing the JSF renderers and solving the JSF commandLink and other component problems to accomplish the rendering as above but that is probably the ultimate answer. I am not a fan of JSF after fighting with it on a few projects now (as compared to lighter weight combinations of concepts from basic HTML/CSS, a sprinkling of JavaScript, clean Java/Servlets, etc).
in your datatable use this one:
<a4j:jsFunction name="selectRow" action="#{userBean.myListener" ...>
<a4j:param name="currentRow" assignTo="#{userBean.selectedRowId}"/>
</a4j:jsFunction>
its called when you select a row, and you can do whatever you want and pass the selected row with the <a4j:param ...as an option you should also be able to call yourLink.click() or something similar, but that wont be the problem to find out...
reference : Richfaces Forum
You may want to try rich:scrollableDataTable. it has attribute onRowClick which you can specify as an event attribute into a4j:support / a4j:ajax nested inside your table. This will make your row clickable.
-cheers :)
For the new RichFaces 4.x, you can use the a4j:commandLink this instead, and make the complete row selectable in CSS. Notice that the 'rowClasses="clickable"' refers to the CSS class to select the whole row:
<rich:column id="fileName" sortable="false" width="618px">
<a4j:commandLink action="#{controller.setSelectedFile(file)}"
oncomplete="window.open('#{menuBar.PrintPage}?outputType=pdf', '_blank');"
rendered="#{not controller.getButtonDisabled(file)}"
execute="#this" limitRender="true">
<h:outputText value="${file}"
style="text-align:left;width:100%;min-width:400px;"
title="${file.name} is viewable.">
<f:converter converterId="MVC.View.Converter_FilePath" />
</h:outputText>
</a4j:commandLink>
</rich:column>
Use this CSS class to select the whole row:
tr.clickable td {
padding: 0;
}
tr.clickable td a {
display: block;
padding: 4px;
}
