Displaying a <p:carousel> inside a <p:dataGrid> using PrimeFaces 5.3 final (community release) something along the following piece of code.
<p:dataGrid var="gridRow" value="#{[1,2,3,4,5]}" columns="1">
<p:carousel var="row" value="#{[1,2,3,4,5]}" numVisible="3">
<p:panel>Panel container : #{row}</p:panel>
</p:carousel>
</p:dataGrid>
Using PrimeFaces 5.2 final, it displays the corresponding UI correctly as shown in the following picture.
Using PrimeFaces 5.3 final, the design is however, severely broken stretching items being held by a <p:carousel> too much horizontally as shown in the following picture.
See the browser's long horizontal scroll bar at the bottom-left corner of the preceding picture.
The problem occurs only when a <p:carousel> is displayed inside a <p:dataGrid> (or likely other iterating components). A <p:carousel> independently displays exactly which it is meant for.
What is the problem with PrimeFaces 5.3? Is there any workaround?
The solution was to set the layout attribute to grid in <p:dataGrid> (due to the responsiveness feature added to PrimeFaces 5.3). The default value of this attribute is tabular.

I'm using the 0.7 version of bootsfaces to create a simple page, which has something like the following:
<h:form id="some_form">
<ui:repeat id="some_elements" var="property" value="#{someBean.properties}">
<b:commandButton value="ShowProp" ajax="true" actionListener="#{someBean.showProperty(property)}" update=":some_form:some_elements:graphic"/>
<!-- This property is true -->
<ui:fragment rendered="#{someOtherBean.showGraphic}">
<h:graphicImage url="gen_image?id=#{property.id}" id="graphic"/>
</ui:fragment>
</ui:repeat>
</h:form>
Now, the idea is that on clicking the button, a property is updated and the image should be re-generated (in this case a jfreechart graph - but this is besides the point.) I tested this with primefaces commandButton and it works fine (the graph is redrawn..) However with bootsfaces commandButton, nothing happens once the ajax call completes (I can see the call on the server side, but the graph is not reloaded.) I think it's down to how it must reference the image in the repeated block, but now sure what is wrong - has anyone come across this?
(NOTE: reason I don't want to use primefaces is that it does not integrate well with bootstrap)
I've opened a bug on the project's bugtracker (https://github.com/TheCoder4eu/BootsFaces-OSP/issues/135).
Actually, why did you expect the update=":some_form:some_elements:graphic" to work in the first place? This expression is an id that doesn't exist. The id is some_form:some_elements:0:graphic. In other words: it contains the row number. PrimeFaces (and Mojarra and MyFaces) recognizes that the command button is part of a UIRepeat group and guesses the correct row number. But that's just a guess. Obviously a reasonable guess, because most of the time you want to update something that's in the vicinity of the command button.
The next version of BootsFaces is going to guess the correct row number, too :).
As per my question title, when I use richfaces, specifically a rich:popupPanel, my primefaces confirm dialog, p:confirmDialog, gets placed top/left justified. If I remove the the richfaces popup panel the primefaces dialog gets centered in the browser window as expected.
I tried changing the order of the namespace entries but that didn't work. What else can I try. I see richfaces also has a confirm dialog that I'm going to look into, it's just that I already had the primefaces version working on other pages, that happen to not have the richfaces popup panel.
I can post code if necessary.
You should not use Richfaces and Primefaces together. There so many conflicts between them both in terms of css and javascript. You can solve css problems by overwriting them and using '!important' at the end of each setting.
for example,
.class{
//...
text-align: center !important
}
However, Your best bet is to use just primefaces
How do I style a primefaces components & specify their positions on web pages ? Links to any sample downloadable application would be highly appreciated.
Position of components:
Primefaces has some components that have position attribute(s) such as p:dialog:
<p:dialog header=”Header Text” widgetVar=”dialog” position=”10,50”>
...
</p:dialog>
In the example the position is given as [x,y] pair related to the top left corner of the browser window. Values such as "top", "bottom", "left", "right" or "center" are also allowed here. If the attribute is omitted, the position of a dialog is centered.
For all other components css positioning can be use either defined by the style or styleClass attribute which is available for a lot of Primefaces components or defined in a separate css layout.
The following example sets an absolute position for the p:dataTable:
<p:dataTable value="#{testBean.selectOptions}" var="item"
style="position:absolute; top:50px; left:240px;">
Primefaces even comes with an own p:layout tag that can be used for positioning as well.
Style
This can be accomplished using Primefaces themes. Furthermore, the Primefaces documentation (you have to pay for since version 2.1) lists all css style classes for each component. You can adapt them to fit your needs.
Say I have a websites with 3 panel grid (just for example..) and I would like to have buttons inside each grid that only cause the contents of that grid to refresh so the rest of the page doesn't necessarily have to refresh.
How do I do that?
I tried to have a form sorround that grid but it seems like the rest of the page still gets refreshed.
A Note - I'm trying to achieve something like what happens when you work with a picklist. when you move the objects between the lists there doesn't seem to be any page refresh...
Thanks!
If you are using RichFaces, you should definitivly check the Ajax chapter of the RichFaces manual. I think you will find everything you need to know there.
Here a small example for partial page rendering:
<a4j:commandButton value="update" reRender="infoBlock"/>
<h:panelGrid id="infoBlock">
<!-- Some content-->
</h:panelGrid>
I am using PrimeFaces and JSF. Can anyone tell me how do I reorder rows of a DataTable using Primefaces drag and drop component?
Currently with in the PrimeFaces framework (v2.2.1 and 3.0) this is not possible with <p:dataTable>.
There is an open PrimeFaces Issue 511 <p:dataTable> draggable columns to add the Yahoo widget datatable draggableColumns attribute to the PrimeFaces <p:dataTable> but no target version is set yet.
If you would like to see this added to PrimeFaces star the issue to help give it higher priority.
This is definitely an older question, but the answer needs updating. This is now doable using the draggableColumns="true" attribute on your p:dataTable.
Your dataTable would then look as such :
<p:dataTable var="i" value="#{bean.data}" draggableColumns="true">

PrimeFaces Showcase : DataTable - Columns Reordering
This feature is now available from PrimeFaces 5.0:
Usage is very simple by just enabling draggableRows option and also an optional rowReorder ajax behavior is provided getting a ReorderEvent with index information for flexibility.
