Re: [exoplatform] FacesContext not accessible in eXo?

[rick joyner <dilbert_future@xxxxxxxxx>]

I should have added that it DOES WORK within the backing bean which is associated with a jsf-page but it DOES NOT WORK from any other bean.

 

Example:

page 1 contains a commandLink or commandButton with a parameter.

 

page1backingbean contains the code segment and can actually access the parameter through the parameter map of the context.

 

but page2backingbean can't access the parameter map.

 

However, if a user clicks on a certain button of page 1, the return value of the action listener says "go to page 2". And page 2 is supposed to access the parameter associated with the button and use it for a query.

 

I am not sure if I am doing something wrong but when I do this in a stand-alone web application, everything works. Only in exo it doesn't.

 

Any idea?

 

Thanks

Hi everyone,

 

When I use a code fragment common in JSF-web applications, all I ever get is "null" which makes me think that the context is not available in exo. Is that correct?

 

<---snip--->

String param = (String) FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("itemID");

int itemID = new Integer(param).intValue();

<---snap--->

 

I use that to pass a simple parameter from one backing bean to another.

In my application, each JSF page has its own backing bean.

Like page1.jsp has a Page1BackingBean.java, page2.jsp has a Page2BackingBean.java and so forth.

 

Page1 contains a list of items.

When a user clicks on an item, Page2 should use the itemID, carry out a database lookup to fetch details on that itemID and display it.

That's what I try to do with the above code sniplet. But it always returns "null". What do I do wrong?

 

Thanks
