Visualforce Second Param not Passing?

Question

I am attempting to extend the functions of our products and show a list on the account page where we can denote what products, services, or reccomendations we've given our clients.

To do this I was creating a visualforce page that would appear to be a related list to our employees with some extended functionality.

The issue is with one of these pieces of extended functionality.

When the employee changes the "Check Back on Date" a pop-up will open asking if they would like to set up a reminder task for the product.

The issue right now is that it's not passing the name of the product.

Visualforce:

<apex:page showHeader="false" sidebar="false" standardController="Account" extensions="AccountProductExtension" action="{!ActionAccountProductRun}">

    <apex:form >
    <apex:pageBlock title="Associated Products and Services">
        <apex:pageBlockButtons location="Top">

        </apex:pageBlockButtons>

        <apex:pageBlockTable value="{!accountProducts}" var="p">
            <apex:column headerValue="Product or Service" value="{!p.name}"/>
            <apex:column title="Type" value="{!p.Type__c}"/>

            <apex:column headerValue="Status">
                <apex:inputField value="{!p.Status__c}"/>
            </apex:column>

            <apex:column headerValue="Date Offered">
                <apex:inputField value="{!p.DateOffered__c}"/>
            </apex:column>

            <apex:column headerValue="Check Back On">
                <apex:inputField value="{!p.CheckBackDate__c}">
                    <apex:actionSupport event="onchange" onsubmit="Confirm();" reRender="out">
                        <apex:param name="cDate" value="{!p.CheckBackDate__c}" assignTo="{!checkBackDate}"/>
                        <apex:param name="cName" value="{!p.Name}" assignTo="{!productName}"/>
                    </apex:actionSupport>
                </apex:inputField>
            </apex:column>

            <apex:column headerValue="Notes">
                <apex:inputField value="{!p.Notes__c}"/>
            </apex:column>
        </apex:pageBlockTable>

    </apex:pageBlock>
        <script>
        window.setTimeout(recursivecall,500);

        function recursivecall()
        {
          window.setTimeout(recursivecall,500);
          autosave();
        }

        function Confirm() {

            if ( confirm("Would you like to set a reminder to check back with the TA of {!Account.Name}?")){
                sendTask();
            }

        }    
        </script>

    <apex:actionFunction name="sendTask" action="{!sendTask}" reRender="out"/>
    <apex:actionFunction name="autosave" action="{!autosave}" reRender="out"/>
    </apex:form>

    <script>
        setFocus = function() { return; }
    </script>
</apex:page>

I couldn't find anything that said setting two param's shouldn't work.

Why will the "p.Name" field not pass into the code?

Answer 1

params are use to assign values to controller variables in a javascript like fashion.

i.e.

<actionFunction name="myfunc" action="{!do something}" rerender="msgs">
   <apex:param value="" name="param1" assignTo="{!myVar}"/>
</apex:actionFunction>

<script>
    myFunc('1234');
</script>

This will assign '1234' to the controller property myVar

Remove the params and it should work as you expect

Update

I made a minimalist copy of what you are doing and it worked fine (with the params) so maybe something else is happening.

BUT - You do not need the params at all so remove them. Here is an example that actually works as expected as well:

Class

public class myTestController{

    public Account a {get;set;}

    public myTestController(){
       a = New Account();
    }

    public void debugValues(){

         system.debug(logginglevel.error,a.Name);

    }



}

VF Page

<apex:page controller="myTestController">


<apex:form >

    <apex:inPutField value="{!a.name}">
        <apex:actionSupport event="onchange" onsubmit="Confirm();" rerender="msgs"/>
    </apex:inputField>


<apex:actionFunction name="sendTask" action="{!debugValues}" reRender="out"/>
</apex:form>

<script>

        function Confirm() {

            if ( confirm("Would you like to set a reminder to check back with the TA of {!a.Name}?")){
                sendTask();
            }

        }    
        </script>
</apex:page>

Since p.name is already set in the controller there is no need to pass it or set it, just grab it in the controller

Answer 2

So I've discovered that even though Name is a text field, it was not passing a text based value with the param.

By using the function {!JSENCODE(p.Name)} I was able to send the proper String value.
