Why doesn't <rich:datascroller> work in a <h:form>? - jsf

I have a jsf page in the form of
<h:form>
<rich:dataTable id="myTable">
<!--Table Data-->
</rich:dataTable>
<rich:dataScroller for="myTable"/>
</h:form>
When the table is in a <h:form> it doesn't scroll (the scroller is disabled) but once I take them out of the <h:form> it works fine. Issue is I need them to be in a form for the rest of my code to work. Anyone know the reason for the issue? I've seen people ask about it but no good answers.

I figured it out. I was using the form in a modal pane and the <ui:include> was within a <h:form> so there was an issue with it being a form within a form.

Adding command button in p:schedule header

How do i add a "custom" button in p:schedule? I tried doing it with the help of a header facet like in the p:dataTable component, but to no avail.
Sorry for being unclear initially, it also probably didnt help that someone butchered my question by editting it's title, here are more details with snippets of code.
I want to do somthing similar to this:
<p:tab title="#{bean.name}" value="bean" >
<f:facet name="title">
<h:outputText value="#{bean.name}"/>
<p:selectBooleanButton styleClass="...">
<p:ajax converter="... />
</p:selectBooleanButton>
</f:facet>
</p:tab>
The code is creating a tab (for an accordionpanel) with a text+button in it instead of the default text only.
I am looking for the same behaviour in a p:schedule component.
<p:schedule value="#{scheduleView.lazyEventModel}" leftHeaderTemplate="today" centerHeaderTemplate="prev, title, next" rightHeaderTemplate="month, agendaWeek" >
<f:facet name="header">
<h:outputText value="#{bean.name}"/>
<p:commandButton styleClass="..."/>
</f:facet>
</p:schedule>
The same add a button to the header principle, except this time on schedule. And of course since schedule does not have any facets available for overwriting this approach does not work.
Finally, my question is: How do I add a button in the p:schedule header like in the picture above?
P.S: Forgive me for confusing you people with datatable, used it because it supports multiple facets (header, footer).
Client side it is all html that can be manipulated with javascript (jquery if you like).
So if you create your schedule and button like this:
<h:panelGroup id="mySchedule">
<p:schedule value="#{scheduleView.lazyEventModel}" leftHeaderTemplate="today" centerHeaderTemplate="prev, title, next" rightHeaderTemplate="month, agendaWeek"/>
<h:outputText value="#{bean.name}" id="scheduleOutputText"/>
<p:commandButton styleClass="..." id="scheduleCommandButton"/>
</h:panelGroup>
You can move the h:outputText and p:commandButton into the schedule with jquery dom manipulation.
$("#scheduleCommandButton").insertBefore(".fc-left");
$("#scheduleOutputText").insertBefore("#scheduleCommandButton");
If you put this script inside the panelGroup and update the panelGroup each time you'd normally update the schedule via ajax, the button and text should be added moved again in an update.
<h:panelGroup id="mySchedule">
<p:schedule value="#{scheduleView.lazyEventModel}" leftHeaderTemplate="today" centerHeaderTemplate="prev, title, next" rightHeaderTemplate="month, agendaWeek"/>
<h:outputText value="#{bean.name}" id="scheduleOutputText"/>
<p:commandButton styleClass="..." id="scheduleCommandButton"/>
$("#scheduleCommandButton").insertBefore(".fc-left");
$("#scheduleOutputText").insertBefore("#scheduleCommandButton");
</h:panelGroup>
You could also put the text and button in a panelgroup and move that by dom manipulation. Just make sure you use the right selectors (I did not prepended the form id to the selectors above). You can also use class selectors instead of id's. That is up to you.
But make sure you use this with care. As #JasperDeVries mentioned in a comment, it is easy to break things. Use it just sparsely, carefully and only as a last resort

How to connect a commandButton with CheckBox

In a html page I have a h:commandButton that I want to make it to work in combination with a h:selectBooleanCheckbox, so every time I press the button the checkbox will be checked and otherwise.
Is it possible to do that directly in the html, and not in the java code behind it?
<h:commandButton value="#{userBean.buttonText()}" action="#{userBean.changeOutput()}"/>
<h:panelGrid columns="4" rendered="#{userBean.details}" styleClass="clicked" >
<h:outputText .... />
<h:outputText ..../>
</h:panelGrid>`
If you are using JSF 2, you have to update the area that include your checkbox, using f:ajax tag.
You can find a lot of examples here in stackoverflow, look this example just hide/show a div: After showing / hiding a JSF element with AJAX how to hide the triggering element?
Hope it helps.

Primefaces : update dialog content and keep it open

I'm working with JSF and PrimeFaces, and I can't handle the following situation:
I have a dialog, and I placed a dataTable on it. In one of the cells of the table I would like to display given data in 3 different ways, and I'd like to switch between them. So far I managed to switch between these rendering types via commandLink, but my problem is that when I click on one of the 3 links, the dialog closes! Can I update the content of the dialog, and be able to keep it open the same time? (I'm updating which render type to use via myMethod)
my commandLink looks like this:
<p:commandLink id="id" update=":myForm:myDialog" ajax="false"
action="#{myBean.myMethod}" oncomplete="dialog.show()">
If i don't use the ajax=false attribute, the method is not called, and I also tried imediate=true, but that's not it either.
You need to define an p:outputPanel inside your dialog and update the outputpanel, not the dialog itself (that's why your dialog closes):
<p:dialog id="myDialog" ...>
<p:outputPanel id="myOutputPanel">
... your dialog content goes here
</p>
</p:dialog>
and change your commandlink
<p:commandLink id="id" update=":myForm:myDialog:myOutputPanel" ajax="true"
action="#{myBean.myMethod}" oncomplete="dialog.show()">
Regarding the oncomplete="dialog.show()" - I'm not entirely sure if you need that. A precise answer can be given if you provide more code regarding your table and code.
I had the same problem, and solution is to update a form instead of dialog. For example:
<p:dialog id="id_dialog" ...>
<h:form id="id_form">
... content
</h>
</p:dialog>
and commandLink:
<p:commandLink update=":id_form" process="#all" ...>
This worked for me!

primefaces panelgrid update from datatable

I am getting "Cannot find component with identifier "contentForm:tabView:form:addressDialogPanel" referenced from "contentForm:tabView:form:addressBookTable" " error. How can I update my panelGrid inside the widget?
<h:form id="form">
<p:dataTable id="addressBookTable">
<p:ajax event="rowSelect" listener="#{addressBookController.onRowSelect}"
update="contentForm:tabView:form:addressDialogPanel" oncomplete="addressDialog.show()" />
</p:dataTable>
<p:dialog id="addressDialogId" widgetVar="addressDialog">
<h:panelGrid id="addressDialogPanel" columns="2" cellpadding="4">
</h:panelGrid>
</p:dialog>
</h:form>
The main problem is that you are giving the wrong client ID of component's. Also p:tabView is a component it is not a form. When you define a h:form, it generates a standart HTML form element. And when you submit the page JSF uses POST to submit your data into backing bean. So nesting them is going to occur lot's of issues that you don't expect. You should seperate forms into sections like sideForm or searchForm or etc.
You should detect the correct client ID of your component when you try to update it. You can do this with your browser's developer settings(press f12 for chrome). Then select component with the magnifier button and give that ID into update property. Just like here:

<rich:datatable> and <rich:datascroller> problem

I am developing a Seam-Jsfv1.2-EJB3 web app.
I have a datatable and checkboxes in each row. Moreover, I have a datascroller at the bottom of my table as well.
My problem is when I click the next page number from the scroller, the selected checkboxes at the first page of the datatable is gone. I mean, even if they were selected, clicking the next page make them deselected. I see it by going back to the first page again by clicking the scroller.
Do you have any idea about that problem?
In order to clearify my case, I attached my code below:
<rich:dataTable
id="apiV2ProductList" rows="10" var="_apiV2Product"
value="#{apiV2ProductList.resultList}"
rendered="#{not empty apiV2ProductList.resultList}" reRender="ds">
<rich:column>
<f:facet name="header">
<h:selectBooleanCheckbox id="selectionCheckAll" onclick="selectAll()" />
</f:facet>
<h:selectBooleanCheckbox id="selectionCheck" onclick="increase(this)" value="#{_apiV2Product.selectValue}" >
</h:selectBooleanCheckbox>
</rich:column>
...
<f:facet name="footer">
<rich:datascroller id="ds" renderIfSinglePage="false">
</rich:datascroller>
</f:facet>
Many thanks in advance.

You can extend the org.richfaces.renderkit.html.DatascrollerTemplate
write your own DataScroller for your own styling by adding a component with the below configuration in faces-config.xml
<component>
<component-type>exCustHtmlDatascroller</component-type>
<component-lass>org.jsf.common.ui.EXCustHtmlDatascroller</component-class>
</component>
<render-kit>
<renderer>
<component-family>org.richfaces.Datascroller</component-family>
<renderer-type>exCustDataScrollerTemplate</renderer-type>
<renderer- class>org.jsf.common.ui.EXCustDataScrollerTemplate</renderer-class>
</renderer>
</render-kit>
Adding an a4j support tag between scroller has solved my problem:
<f:facet name="footer">
<rich:datascroller id="ds" renderIfSinglePage="false">
<a4j:support event="onpagechange"/>
</rich:datascroller>
</f:facet>
However the other thing is, I am using JQuery to style my table (ex. on mouse over and out), and this time, when I click the next page of my table, the style is gone.
Any help would be great, many thanks in advance.
**
PS: BTW the wierest thing to my mind is it comes me impossible to find a solution by yourself for this kind of problems. Your creation may not always be enough to solve (at least here in my example, adding a4j:support thing) I am asking experts, how can we handle that kind of things by ourselves...

You don't need jQuery for styling the datatable
<rich:dataTable id="dataTable" var="x"
onRowMouseOver="this.style.backgroundColor='#F1F1F1'"
onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
The problem you were seeing with the styles being removed is due to the nature of AJAX, and the way the table is reRendered.
Assuming you were firing the initial styling call based on some form of page onLoad, the first time the page is rendered, your styles will be applied. However, when you click the "next" button with the paginator, you are pulling a lot of new HTML down, and replacing the old HTML in the table with the newer, updated information. The proble you're seeing is that you saw styling because jQuery applied styles to the old nodes, upon reRender, those nodes are completely thrown away, along with their styling. You simply need to figure out the hook to call the "styling" method, and re-execute that call after the table is re-rendered.
Generally, I use an a4j:status tag, and set up the onstart or onstop to re-parse the table.
