Method value not refreshing

[Thalvik]

Hi to all.I am new to Java, and i've been so far developing in VB.NET.The syntax is very different, and that is a little problem to me.I am writing a program on JavaME in NetBeans and i have the method:

private void pokazi(String link){
     String url = link;
        if (zavrsna == null) {
            // write pre-init user code here
            zavrsna = new Form("form1");
            zavrsna.addCommand(getBackCommand9());
            zavrsna.setCommandListener(this);

            StringBuffer buffer = null;
            try{
            StreamConnection conn = (StreamConnection) Connector.open(url);
            InputStream in = conn.openInputStream();

buffer = new StringBuffer();
int ch;

while ( (ch = in.read())!= -1){
buffer.append( (char) ch);

}
}
catch(Exception o){
o.printStackTrace();
}

zavrsna.append(new StringItem(null, buffer.toString()));
display=Display.getDisplay(this);
display.setCurrent(zavrsna);
url = null;
        }
    }

It's just fetching some string from webpage and it's working fine.I have a list with listitems that is calling the method:

public void polazak1Action() {
        // enter pre-action user code here
        String __selectedString = getPolazak1().getString(getPolazak1().getSelectedIndex());
        if (__selectedString != null) {
            if (__selectedString.equals("Polazak M.Naselje")) {
                if (dan1.equals("Workday")){
                    pokazi("http://www.orion.naissus.info/index.asp?id=4");
                    
                } else if (dan1.equals("Satrday")){
                  pokazi("http://www.orion.naissus.info/index.asp?id=5");
                   
                } else if (dan1.equals("Sunday")){
                    pokazi("http://www.orion.naissus.info/index.asp?id=6");
                    
                }
       }
}

When it's called the first time, it works, but when I want to change to another item in list, nothing happens.I've tried to clean url in method by

url= null;

or

url= "";

but it didn't work.I also don't know how NetBeans handle breakpoints in IDE.

In hope that you will help me, best regards Aleksandar.

It's hard to make out because the code is so poorly formatted, but it looks like pokazi only does something if zavrsna is null, and zavrsna is only null the first time through...

Wow,it works, i've missed that.Ty very much. 8)

No problem.
