passing parameters
I am trying to pass a parameter to a controller. I have this block in my page:
<apex:outputText>
<apex:param name="thisParam" assignTo="{!CityO}" value="{!$CurrentPage.parameters.oCity}" />
</apex:outputText>
Then my controller has this:
public class LaneDetailCon {
public static String CityO { get; set; }
public PageReference setParams()
{
return null;
}
static List<Lane_Detail__c> lanes { get; set; }
public static List<Lane_Detail__c> getLanes()
{
System.debug('The origin city is ' + CityO);
There are no errors, thus the code executes, however, my paramater OCity returns as null. What does the apex:param action not pass the variable to OCity?
<apex:outputText>
<apex:param name="thisParam" assignTo="{!CityO}" value="{!$CurrentPage.parameters.oCity}" />
</apex:outputText>
Then my controller has this:
public class LaneDetailCon {
public static String CityO { get; set; }
public PageReference setParams()
{
return null;
}
static List<Lane_Detail__c> lanes { get; set; }
public static List<Lane_Detail__c> getLanes()
{
System.debug('The origin city is ' + CityO);
There are no errors, thus the code executes, however, my paramater OCity returns as null. What does the apex:param action not pass the variable to OCity?
Greetings!
The code looks fine to me.However,I would suggest you to have a look at the simple example to pass parameters from VF page to Controller.

This is now my apex:page
<a href="javascript:jsActionFunction('Cincinnati');">Send Param To Apex</a> <br />
<apex:outputPanel id="vfParamPanel">
The value of parameter is : {!$CurrentPage.parameters.oCity}
</apex:outputPanel>
<apex:actionFunction name="jsActionFunction" action="{!doActionFunction}" reRender="vfParamPanel">
<apex:param name="vfParam" value="{!$CurrentPage.parameters.oCity}" assignTo="{!vfParam}"/>
</apex:actionFunction>
My controller now:
public class LaneDetailCon {
public String vfParam { get; set; }
public LaneDetailCon(){
}
public PageReference doActionFunction(){
// Do Something...
System.debug('The origin city is ' + vfParam);
return null;
}
}
