Command Link not invoking Backend Bean

abdulrahmanar · 10 Jul 2017, 09:47

Hi,

Based on this topic i have searched a lot, after trying all the suggestions i couldn't find solution to my problem. So only i am posting this.

I have a datatable -> column -> commandlink.

When i click the commandlink, the backend bean has to invoke and update the values of the bean and same to be update in the datatable.

Whenever i am clicking the commandlink on the first page(pagination), the call is invoking. If i click on other pages(other than 1st page), it doesn't invoke the backend bean rather it redirects to the 1st page of the datatable.

I have tried many solutions like ajax=false or true, process="@this", action or actionListener, kept bean in ViewScope or SessionScope.

Environment:
IBM WebSphere Portal 8.5

Following is the code, please help to suggest the solution.

Code: Select all

<!-- jsf:pagecode language="java" location="/src/pagecode/CommandLinkTestView.java" --><!--/jsf:pagecode -->
<div xmlns:ui="http://java.sun.com/jsf/facelets"

And an h:body and h:head inside a div???

abdulrahmanar · 27 Jul 2017, 10:14

Hi,

I have tried all the solutions in the provided link, still it's not working.

Yes, h:body and h:head are inside the div.

I think you should replace this :

Code: Select all

<div xmlns:ui="http://java.sun.com/jsf/facelets"
	xmlns:f="http://java.sun.com/jsf/core"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:portlet="http://java.sun.com/portlet_2_0"
	xmlns:p="http://primefaces.org/ui">
	...
</div>

with this :

Code: Select all

<html xmlns:ui="http://java.sun.com/jsf/facelets"
	xmlns:f="http://java.sun.com/jsf/core"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:portlet="http://java.sun.com/portlet_2_0"
	xmlns:p="http://primefaces.org/ui">
	...
</html>

You also have a typo here

Code: Select all

<div class="ui-g-12 ui-lg-12 ui-md-12".

which should be

Code: Select all

<div class="ui-g-12 ui-lg-12 ui-md-12">

Hi,

I have tried with html, it's not working.

Typo is because of i have typed the entire code, i haven't done the copy and paste. So in my original code, it is closing tag not full stop.

kukeltje · 31 Jul 2017, 09:47

Yes, h:body and h:head are inside the div.

That is wrong

pilpin · 31 Jul 2017, 10:23

Could you show us the code for the commandLinkCheck method ?

abdulrahmanar · 16 Aug 2017, 08:56

Hi,

I have made it to work by following link suggestion.

https://stackoverflow.com/questions/316 ... -datatable

In case of dead link, here is the solution.

Use rows and first attributes in datatable, and bind it to the back end bean like below.

first="#{bean.first}" rows="#{bean.rows}".

Don't forget to create getter and setter for both fields.
