JSF 1.2 - Problem with passing page count to bean to create list

Question

I have this select option:
<f:verbatim>Pages: </f:verbatim>
<h:selectOneMenu id="selectPage" value="#{pageList.selectedPage}">
         <f:selectItems value="#{pageList.selectPages}" />
</h:selectOneMenu>And the backing bean (called mybean2) for this is:
private int pages;
public void getPages(int Pages)
     this.pages = Pages;
// getter methods
public List<SelectItem> getSelectPages()
     selectPages = new ArrayList<SelectItem>();
        pages++;
        for (int i = 1; i > pages; i++) {
             selectPages.add(new SelectItem(Integer.toString(i), Integer.toString(i)));
         return selectPages;
public String getSelectedPage()
         return selectedPage;
// setter methods
public void setSelectPages(List<SelectItem> selectPages) {
        this.selectPages = selectPages;
public void setSelectedPage(String selectedPage) {
         this.selectedPage = selectedPage;
}The getPages method above gets the page count from mybean1.submit method. Thus, for example, when the submit method returns 30, how am I able to pass this value into the getSelectPages so I can dynamically created the number of pages

You could store the value in the session and remove it when you need to use it.Thanks, r035198x. I tried that before and users from other Java forums suggest that I shouldn't do it this way as I am adding more codes than necessary to pass technically a value from one bean to another. Hence, I decided to follow their advice and went and created a generic bean that can be referenced by other beans for pages calculation. Some users also suggest using Dependency Injection (available for JSF 1.2) to try to accomplish the result I want. I've also read about this method in JSF 1.2 spec - but without much example, I'm pretty much in the dark as to how this work. Unfortunately, I've only been on JSF for the last 4 weeks so I'm still a newbie - please excuse any "dumb" questions I have asked on this forum so far...
What I currently has working for me is moving the method to calculate the pages from mybean1 to mybean2. This means all I have to do now for the other beans (11 remaining) is passed a few parameters to mybean2's method that calculate pages.
