I am trying to layout a page with Bootsfaces and JSF 2.2. I like to show only three column in a row and then start new row but don't know, how to implement this.
<h:form>
<b:container>
<b:row>
<ui:repeat value="#{ClientBean4.custs}" var="custs">
<b:column col-md="4"><h:outputText id="output" value="#{ClientBean4.counter}" /> </b:column>
<h:panelGroup rendered="#{ClientBean4.counter == 0}">
</b:row><b:row>
</h:panelGroup>
</ui:repeat>
</b:row>
</b:container>
</h:form>
after a long time, I wrote above code, but it's givng error like 'h:panelgroup' should be properly closed. It's giving meaning, that I started panelGroup and then closing a row, starting a new row, and then close panelGroup.
So, Is anyone have idea, how to implement a layout, where a row will have three columns (showing customer's object details per column), then close the row and start a new row. obvisouly, I dont know, how many objects will be in the list.
BootFaces offers a component that handles this. More specifically you can use <b:panelGrid columns="3"> to achieve this. This will give you a dynamic grid system that will grow vertically as you populate it but retain the number of rows that you specify.
You can see the component in action here, https://showcase.bootsfaces.net/layout/panelgrids.jsf
PrimeFaces also has a component for this, but I assume you want to use BootFaces as your original code uses it. If you prefer PrimeFaces, you can use the <p:dataGrid> component, which does something similar. This component even handles pagination.

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 :).
I am looking for something like <rich:popupPanel> in RichFaces 4, but then for RichFaces 3. I haven't found anything like in documenation. There is only <rich:modalPanel> which doesn't suit my needs, because it has problems displaying my datamodel in table. The selection doesn't work, it always returns no rows selected. If I put my table component in <rich:panel> or <rich:togglePanel>, then it works fine.
Is there any popup window excluding <rich:modalPanel> in RichFaces 3?
I dont have 50 reputation to ask you more details in a comment, so i will answer directly hoping this is what you're asking about.
I think you mean that your problem is that the content of the ModalPanel is not rerendered dynamically. but for this you can wrap your table (or the components you want to update) in an <a4j:outputPanel> with ajaxRendered="true"
Setting ajaxRendered="true" will cause the <a4j:outputPanel> to be updated with each Ajax response for the page, even when not listed explicitly by the requesting component. This can in turn be overridden by specific attributes on any requesting components.
http://docs.jboss.org/richfaces/latest_4_0_X/Component_Reference/en-US/html/chap-Component_Reference-Containers.html#sect-Component_Reference-Containers-a4joutputPanel
In my code I have something like :
<a4j:commandLink id="timelineBtn" action="#{timelineBean.doGenerateLog}"
oncomplete="Richfaces.showModalPanel('timelinePnl');return false;"
value="#{labels['timeline.button.lbl']}"/>
that opens the modalPanel :
<rich:modalPanel style="width:800;height:600;" id="timelinePnl">
<a4j:outputPanel id="dataPanel" ajaxRendered="true">
<!-- your components to be updated go here -->
</a4j:outputPanel>
</rich:modalPanel>
So my content is updated with the results of my timelineBean.doGenerateLog method each time i open the modalPanel .
I have a data entry form where user enters lots of data. When user comes to the page to view existing data, the page should be displayed in read-only mode (all values shown as text), when he clicks 'Edit' button, normal form with all input controls should be shown so that user can change and save data.
We are using JSF 2.0 with PrimeFaces library. It is easy to achieve above behavior for text box and text area but not for Checkbox, multi-select, radio,..... controls. Is there any easy way available to achieve above behavior rather than writing our own code (which may run into lot of lines thus making backing bean code ugly)
Thanks for your help...
I'm not sure why you think that you need additional backing bean code for this. You've all the needed values in the backing bean already. Your problem is more in the presentation of those values. Just display them in the desired format by writing the view code accordingly. Perhaps you were thinking it too the hard way.
Instead of a select boolean checkbox, you could display for example a "Yes" or "No" value.
<h:selectBooleanCheckbox value="#{bean.checked}" rendered="#{bean.edit}" />
<h:outputText value="#{bean.checked ? 'Yes' : 'No'}" rendered="#{not bean.edit}" />
Instead of a select one menu/radio, you could just display the value in an output text.
<h:selectOneMenu value="#{bean.selectedItem}" rendered="#{bean.edit}">
<f:selectItems value="#{data.availableItems}" />
</h:selectOneMenu>
<h:outputText value="#{bean.selectedItem}" rendered="#{not bean.edit}" />
Instead of a select many listbox/checkbox, you could just display for example all values comma separated in a loop.
<h:selectManyListbox value="#{bean.selectedItems}" rendered="#{bean.edit}">
<f:selectItems value="#{data.availableItems}" />
</h:selectManyListbox>
<h:panelGroup rendered="#{not bean.edit}">
<ui:repeat value="#{bean.selectedItems}" var="selectedItem" varStatus="loop">
#{selectedItem}#{not loop.last ? ', ' : ''}
</ui:repeat>
</h:panelGroup>
You could wrap it all in a tag file or a composite to minimize boilerplate and code repetition.
I've done this in my last project using composite components which has a "preview" attribute and in the implementation I render a text when this attribute is true and the real (editing) when the attribute is false. For checkbox in preview mode you could show the checkbox itself but disabled, for radio - show the selected item.
MyFaces Tomahawk library [1] contains an extended version of the standard components that adds displayValueOnly attribute for this purpose. This might help you (I haven't used them).
[1] - http://myfaces.apache.org/tomahawk-project/tomahawk20/index.html
We have a page in a seam application using richfaces that contains an extendedDataTable plus one or more list boxes. We've found that, once you select something in the extendedDataTable and then switch to one of the list boxes, the extendedDataTable keeps responding to the up and down arrow keys, so if you use them to change the selection in the currently highlighted list box, the selection in the extendedDataTable changes as well.
Is there a workaround to stop the extendedDataTable changing selection when it doesn't have focus?
Unfortunatly the code is rather complex, but the xhtml for the table is (without all the columns for simplicity):
<rich:extendedDataTable id="jobManJobListTable" enableContextMenu="false"
value="#{jobman_view.paginatedJobList}" var="job" rows="25" selectionMode="multi"
selection="#{jobman_view.jobListSelection}" height="">
<a4j:support event="onselectionchange" reRender="detailsDiv,customerDiv"
action="#{jobman_view.onJobSelectionChange()}"/>
<rich:column width="10%" sortable="true"
label="#messages['jobman.ui.joblist.table.column.heading.type']}">
<h:graphicImage value="../img/job_type_#{job.jobType.imageName}_16x16.png"/>
<rich:toolTip>
<span style="white-space: nowrap">
<strong>#{job.jobType.name}</strong>
</span>
</rich:toolTip>
</rich:column>
</rich:extendedDataTable>
Note the table is not included in any of the divs listed in the a4j:support Rerender.
As for the backing bean, the paginatedJobList is just a list of jobs, onJobSelectionChange changes job the backing bean thinks is selected so that the detail div's contain the correct data when reRendered, and jobListSelection is just a getter/setter for a SimpleSelection.
It seems to be related to the a4j:support, without it the selection doesn't apear to change when another control has focus.
You can write a smart JS function and attach it to onkeypress attribute of the extendedDataTable
This function could disable the scrolling when something is selected, and enable back to it when nothing is selected.
Hopefully the title isn't too cryptic ...
The problem we have is that we generate a bunch of input controls (h:inputOneMenu, h:inputText etc) from some Java List.
Works fine EXCEPT the requirement is that these inputs validate on the fly. Again not so hard except that as there controls were generated in a loop the only possible reRender action is basically the entire form or an a4j:outputPanel around each loop iteration which is basically the same thing.
Now the above two solutions technically work but they have the nasty side effect of reRendering all the page controls which makes the page feel really twitchy and clunky. We'd like to stop this from happening so ideally the only control that gets reRendered is the control that send the ajax update/validation.
Basically this is our page code:
<ui:repeat value="#{seam-outjected-list}" var="item">
<a4j:outputPanel selfRendered="true">
<h:inputText value=#{item.value}>
<a4j:support event="onblur" ajaxSingle="true" />
</h:inputText>
</a4j:outputPanel>
</ui:repeat>
I've left out a bit of stuff that just renders different controls depending on the item.
As you can see we're currently using the a4j:outputPanel solution so every time any loop generated control is updated all the controls are reRendered.
Thanks in advance if anyone has any thoughts.
My first thought is that you should try replacing your <ui:repeat> with an <a4j:repeat> and take advantage of the ajaxKeys attribute to only reRender certain rows.
From the Richfaces Docs:
The main difference of this component
from iterative components of other
libraries is a special "ajaxKeys"
attribute. This attribute defines row
keys that are updated after an Ajax
request. As a result it becomes easier
to update several child components
separately without updating the whole
page.
