Thanks for the response. I need to display the entire table on expand and hide it on collapse. Yeah it isn't going to collapse "else" section when I debug the code. Is the place where the method called wrong?
I've a table which has multiple columns as in my database table. Few of the columns are editable and the values entered by the user should be updated back in the database on click of submit. For this Ive a foreach loop with value as HashMap of list of bean.
Below is my foreach loop:


I'm iterating through a map called feeApprovalByFundId which is Map<String,List<MyBaseBean>>. How do I get the updated values of the columns like checkbox, input box? I'm able to get in a String or String array but I won't know to which key was that mapped to. (Eg. Fund1 will have 10 fees - I will have under one hashmap key).
I tried iterating like this :

Is this change for the lifetime of the application or some other combination?



I want to retrieve the latest values from the cache when the database is updated. It is fetching the new values after 120 seconds. How do I change?
I want to use a Second-Level chache in my code which has Spring and hibernate. I've made all the configurations in spring-persistence.xml for Ehcache configuration and the cache is working fine. My problem is that the configurations are already set by default in the ehcache-failsafe.xml. When I change the value in database and refresh the page, the changes are not reflected immediately since the timeToIdleSeconds="120" in the xml. I want to change this to 0 so that the changes are reflected immediately. I tried doing this : CacheManager manager = CacheManager.create();

Hi,

I'm trying to bind a p:datatable from JSF 2.0 Custom Component through Encode Method and I'm able to bind it also, with an issue.

This is my custom Tag in the xhtml page :



and at the encode method i've the following :



But when I try to run this it throws an exception saying p:datatable has to be within a form element, though my custom tag is within h:form tag

So I tried adding this line :



Now it adds the datatable. But one table within the custom tag as I'm doing this in encode method and one more in the form at the top as I've added to the form.

How do I solve this issue? Kindly help me out.

Thanks in advance

Hi all,

How can I update a datatable from the backing bean? I'm using JSF 2.0 and Primefaces 2.2.1.
I'm doing this by JSF custom component. So I've to bind the datatable from the encode method. And in run time I should update the table after entering few details in the other fields.
I tried populating through p:commandbutton(setUpdate) from back end. But it says I can't create a p:commandbutton without a form though I've a form in my xhtml page.

Hi all,

I'm searching for a basic Spring Web Flow application code on net but I'm unable to find. I'm suppose to cover the 3 chapters in the Web Flow tutorial given in the Springsource through an example. But the simple example is not found. Can someone please help me with a sample web flow application?

thanks in advance

I have a requirement to create a panel dynamically using jsf 2.0 custom components. The controls within the panel will be dynamically read from an xml and rendered on the selection of the corresponding object (Eg : If Person is selected, I should render a panel which will have controls related to person like : Person age field(inputtext), Person DOB(calendar) and so on).

I am trying to render it from the component class which extends UIComponentBase.


I have done this way. But I am getting a null pointer exception. How can the panel with the defined controls be rendered dynamically?

This is what I'm getting -

====Will Start Rendering====
inside the panel get method------

Hi,

I'm trying to use the Ajax with JSF 2.0 to render a panel on button click. In JSF 2.0 we've f:ajax for rendering dynamically. But in the samples i found online, I only saw outputtext being rendered. I'm trying to render a panel but it gives an exception.



But i get the following exception -

This is my web.xml entry.



This is the exception I'm getting along with the exception already posted :

What is the reason? Are the Jar files that are causing the problem? Or is it the web.xml mapping? I'm using JSF 2.0 with Primefaces 2. I should use the UIComponentBase class to define the JSF custom component. the Jar files might not be compatible is my analysis. Kindly help me. I'm stuck since 3 days.

JSF can be integrated with spring (REST webservices APIs to be included) to make it RESTful. There is a step by step tutorial in the IBM website about using the REST webservice along with spring and JSF. You can check the same for more information.
