White Space selectOneMenu

Question

I would like to know if it is possible to remove a blank field in selectOneMenu, I have the following case, I have a selectOneMenu that displays several names, some names that I do not want to appear I used . replace("name",""), only now selectOneMenu kind of skips a line where it had the name I gave the . replace, how do I now remove this blank line ?

below is the method I am using to list in selectOneMenu it takes the name of the files that are in a directory

public ArrayList<String> SearchFileStop (String p) throws SQLException{

    DirControle dc = new DirControle();
    File file = new File(String.valueOf(dc.selectedDir_CB()).replace("[", "").replace("]","")+"\\"+p);
       File afile[] = file.listFiles();
       int i = 0;
       for (int j = afile.length; i< j; i++){
           File arq = afile[i];

          listaFiles.add(arq.getName().replace("datasulDescargaBancos.bat","").replace(" ",""));
       }

       return listaFiles;
    }

my bean

public ArrayList<String> selectedFile(String arq) throws SQLException{return sdir.SearchFile(arq);} 

The Selectonemenu, in this case the problem is in the second:

                                <f:selectItems value="#{dir_controle.selectedDs()}"  />
                                <p:ajax listener="#{scripts.listener}" update="arquivo" /> 

                            </h:selectOneMenu>

                            &nbsp;&nbsp;<label class="title4">Banco:</label>&nbsp;&nbsp;
                            <h:selectOneMenu id="arquivo" value="#{scripts.arquivo}" style="width: 200px">
                                <f:selectItem itemLabel="Selecione"/> 
                                <f:selectItems  value="#{dir_controle.selectedFile(scripts.pasta)}" />

                            </h:selectOneMenu> 

Answer 1

Friend, the problem is not in jsf, but in its logic to the popular the list of String.

If you need the file name to be completely empty, do not include it in listaFiles, just do not insert in listaFiles.

listaFiles.add(arq.getName().replace("datasulDescargaBancos.bat","").replace(" ",""));

In the line above, you don’t care about that. The right thing would be to do something like this:

String nomeAhSerInseridoEmLista = arq.getName().replace("datasulDescargaBancos.bat","").replace(" ","");
if(!nomeAhSerInseridoEmLista.isEmpty()) {
    listaFiles.add(nomeAhSerInseridoEmLista);
}
