So, like the title says in my case height of the extendedDataTable doesn't work, so my table also doesn't scroll because all rows are shown. I'm using richfaces4.0-final version. So here is my piece of code:
<rich:extendedDataTable
value="#{advancedSearchView.criteria}" var="criteria"
height="50px"
selection="#{advancedSearchView.selection}" id="table"
selectionMode="single">
<rich:column id="criteria_row" filterBy="#{criteria}" filterEvent="onkeyup" width="500px">
<h:outputText value="#{criteria}" />
</rich:column>
</rich:extendedDataTable>
AdvancedSearchView is request scoped bean, and criteria is an array of Strings.
I hope that is enough information. Thank you in advance. A would really appreciate if someone gives me an answer, because I'm struggling with this for a while.
According to the RichFaces 4 VDL (View Declaration Language) documentation, the <rich:extendedDataTable> component does not support the height attribute at all.
Your functional requirement is however understood. You want to render the extended datatable with a height of 50px and make the table body scrollable. You need to achieve this using the usual CSS means by style attribute which can take inline CSS declarations, or by the styleClass attribute which can take CSS classes, like as on almost every other JSF HTML component.
So, with style
<rich:extendedDataTable ... style="height: 50px;">
or, with styleClass (which is also the more recommend practice; separate style from markup)
<rich:extendedDataTable ... styleClass="criteria">
and this piece in a CSS file which you include by <h:outputStylesheet />:
.criteria {
height: 50px;
}

This is the code in the body of my .xhtml file. The bars were showing before (I don't remember changing anything significant) but now just the value is displayed.
<p:progressBar value="#{bean.value}" labelTemplate="{value}%" styleClass="animated"/>
<p:progressBar id="progress" interval="100" rendered="true" ajax="true" value="#{bean.value}" widgetVar="pbAjax" labelTemplate="{value}%" style="width:300px; font-size:12px"/>
The second bar is derived from this answer but the problem still remains the same.
<p:progressBar value="50" labelTemplate="{value}%" displayOnly="true"/>
This is the code from primefaces, which also does not show up as a bar but just as a value.
I would appreciate it you could clarify if I have some major misunderstanding of how the progressBar works.
Use Firebug or your browser's WebDevelopment Tools to check if the progressbar is properly rendered:
Check for Javascript Errors
Is the right CSS Style applied or are you overwriting primefaces css classes?
Are you using your own JQuery Version? It can come to conflicts between your JQuery and Primefaces' one.
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

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.
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;
}
Should be simple but I couldn't find the answer, I would like to place components horizontally instead of vertically.
What I'm trying to achieve is a rich:toolbar with 2 or more rows. I've been trying to do that with a toolbar that has a panelgrid and two panelgroups like this:
<rich:toolbar...>
<f:panelgrid columns="1"...>
<f:panelgroup id="row1" .../> <-- Should be horizontal placement
<f:panelgroup id="row2" .../> <-- Should be horizontal placement
<f:panelgrid/>
<rich:toolbar/>
So how do I make the panelgroup layout horizontal (Or should I use something else?)
Thanks!
You probably already know that JSF in webserver ends up as HTML in webbrowser. In HTML, there are several ways to place elements horizontally (eventually with help of CSS):
Group them in inline elements (like <span> or any element with display: inline;).
Group them in block elements (like <div> or any element with display: block;) and give them all a float: left;.
The JSF <h:panelGrid> renders a HTML <table> element wherein each child component is taken as a <td>. The columns attribute represents the max amount of <td> elements in a single <tr> (so that the <h:panelGrid> knows when to put a </tr><tr> in). The JSF <h:panelGroup> renders a <span> element.
To achieve way 1 with JSF, you just need to group them in separate <h:panelGroup> components.
<rich:toolbar ...>
<h:panelgroup id="row1" ... />
<h:panelgroup id="row2" ... />
</rich:toolbar>
Way 2 can be done the same way, but then with <h:panelGroup layout="block"> instead and a float: left; in their CSS.
