Actionfunction doesn't work

Question

I cannot find the reason of this situation. Please help experts.

I have several actionfunction and all of them are using for saving value to Controller variables.

I this situation, one of them doesn't work even if I tried so many modification..

Code is here

<apex:form>
            <apex:commandLink action="{!passParam2}" value="Submit" 
                target="_blank" 
                styleClass="btn btn-primary" 
                style="padding: 4px; text-decoration: none;" 
                reRender="resultPanel" 
                status="myStatus">
                <apex:param name="firstparam" assignTo="{!bookingid}" value="{!$CurrentPage.parameters.bookingid}"/>

            </apex:commandLink>
        </apex:form>

Controller code

public PageReference passParam2(){
    bookingid = ApexPages.currentPage().getParameters().get('bookingid');

You can try a efficient approach with the use of apex:commandLink. No need to use actionFunction

As per your code, you want to display a Submit button and onclicking you will assign value to bookingid, as well as calling controller method passParam and navigate to visualforce page.

• button class with help you to display as button.
• apex:param will pass value to controller
• action will call controller method.

Visualforce

<apex:commandLink action="{!passParam}" 
    value="Submit" 
    target="_blank" 
    styleClass="btn" 
    style="padding: 4px; text-decoration: none;" 
    reRender="resultPanel" 
    status="myStatus">
        <apex:param name="firstparam" 
           assignTo="{!bookingid}" value="{!$CurrentPage.parameters.bookingid}"/>
</apex:commandLink>

Controller

public String bookingid {get; set;}

public PageReference passParam(){

    //navigate to visualforce page. 
    PageReference pg = Page.page1;
    pg.setRedirect(true);
    return pg;
}
