Problem with <h:commandButton>

Hi ArAsh Dex ,

Thanks for your reply.
I have tried hardcoding rendered="false" for the button. After doing so, button did not display on the browser but, my other buttons for other pages are not working again......same problem.

I thought of implementing your bean code. I am confussed and not able to understand what is the meaning of
-->this.att="Okay".....Okay stands for what??

Can you please help me.... :(

how to extract data and represent it on browser

Hi,
I am creating a menu UI. I have xml data to describe menu, submenu, subsub menu etc.... I want to extract these menu items and display it on the browser.

On the home page, i need to display only first level menu..Once i click on any first level menu, it should take me to that particular page and display second level menu under first level menu.. how do i do it?

Do i need to use xpath? or do i need to use only xml query? How do i relate second level menu to first level menu ?
my xml structure as follows:

on the browser,(home page), only File and Edit need to displayed. Once i click on file-> it should take me to another page/same page and display second_level menu->New. If i click on New, it should display all the third_level items under NEw. How do i do this? I need only the logic.... I don't want to hardcode anything...everything should be automatic.

Can any one please help me

problem in getting xpath of each node.

I would like to get xpath of each element in xml document.
I have written the code, but the last element's number is
getting incremented where i want that to start from [0].

Can anyone please help me?

My code as follows:
book.xml

my java program is:

import java.io.File;
import java.util.HashMap;
import java.util.Map;
import java.util.Stack;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
/**
* SAX handler that creates and prints XPath expressions for each element encountered.
*
* The algorithm is not infallible, if elements appear on different levels in the hierarchy.
* Something like the following is an example:
*
* for above book.xml, my program will report
*
* //book[0]
//book[0]/person[0]
//book[0]/person[0]/first[0]---> This segment is working fine.
//book[0]/person[0]/last[0]
//book[0]/person[0]/last[0]/name[0]
//book[0]/person[0]/age[0]
//book[0]/person[1]
//book[0]/person[1]/first[1]->(this is wrong: should be //book[0]/person[1]/first[0])
//book[0]/person[1]/last[0]
//book[0]/person[1]/age[0]
//book[0]/person[2]
//book[0]/person[2]/first[2]-> (this is wrong: should be //book[0]/person[2]/first[0])
//book[0]/person[2]/last[0]
//book[0]/person[2]/age[0]
*
* It also ignores namespaces, and thus treats <foo:elemA> the same as <bar:elemA>.

how to retain active tab-when user navigates to other control in a page?

Hi, I have a web page with RHS part with tabbed menu and another LHS part=event calendar. There is no link with event calender and tabbed menu except that they both lie on the same page.

My problem is:

As soon as page loads,

1) When I click on default tab first, Nothing will change in the page.(working fine)

2)When I click on any other tab(except default) first, and then move to event calendar or any other control in the page, which ever tab is active is getting deselected.

3) When page loads, if I click on event calendar first, default tab is not getting affected. (it will be active till I click on it or any other tab--working fine)

Don’t know where it is going wrong.
My expectation is:
1) As soon as page loads, I will click on any other tab (tab3)..Then I move to event calendar to see events on next month. Even after clicking event calendar, I want tab3 to be active... how to do it???

Please help.
