Method in Backing bean doesn't work

[Victor Sosa]

Hi, this si my first post in the forum, I hope you can help me because i'm geeting crazy with this.

I have a jsf page, with vusal jsf, and a div container, in this container i also have a Layout panel, and inside this four hiddenFields. This hiddenFields are wired to a managed bean.

When i submit the page it just don't do the method, instead, do init, set's and get's and preprocess methods and break the work with no Exceptions in the server, Glassfish V2.

But when I comment the lines of the hiddenFields in my jsp it work's wonderful.

Any advice, please?

Add <h:messages /> to the page to take note of any conversion and validation errors. Read the application server logs as well, it might contain some warnings.

I try this with a messageGroup to print all system messages, but in the postback didn't print anything, so i think there is no errors, from the server view, in the request.

Please anyone who can help me

[Victor Sosa]

ok, I did this.

change the hiddenFields to textField, so i can see the values of them, and add a message to each text.

now when i press the button and the page is returned, print me a NullPointerException i one textField, the strange thing is that I use this textField for an ajax operation and do it well, so I can't find why is the NullPointerException.

Can you help me?

I check my code and result that I was submiting a value, and in hte set method of that value i was using another value not yet submitted, so there is de NullPointerException, but I'm in the start point, it just don't do the action method of the button.

Do all the get's and set's, but no the action method.

I'm working on that, but if someone has an idea, please do tell

[Bauke Scholtz]

Show the commandButton code line and the action method code snippet.

I find what was my problem.

In javascript I set disabled my button and in the server just set null in the action of the bean, and never get in the method.

Sorry for al the problems guys. Thank you so much.

Yes, if you set some input element to disabled, then its name/value pair won't be sent as request parameter to the server side. If it concerns the submit button, then that way JSF won't know if any button was pressed.
