Background: I created a VisualForce page with the intention of embedding it inline into an Opportunity layout. I've used the standard Opportunity controller with a controller extension. On this page, there is a custom selectOption list with 5 values:
--None--, Tier 1, Tier 2, Tier 3, Custom
If you choose Tier 1, 2, or 3, a method runs via onchange actionSupport, and it updates the opp based on pre-defined conditions of each Tier, which I pull from a Custom Setting. If you choose --None--, it updates the opp back to null for all appropriate fields. In each of these scenarios, I also re-render the pageBlockSection that holds these fields, so that changes can be seen immediately upon changing the selectOption.
All of this works as expected, except for the 'Custom' selectOption...
Problem: When choosing the 'Custom' option from the picklist, I set a Boolean called isCustom to true, and then the same re-render occurs. This time however, the re-rendered section sees that isCustom is true. In the case of this Boolean being true, I hide all of the outputFields (via the render (true/false) param), and display inputFields instead, with the intent of allowing the user to enter custom rate information. However, for some reason these inputFields are rendering without field Labels, and I'm not sure why, how to resolve it, or if this is a bug.
Question: Why are my dynamically rendered inputFields not displaying field Labels?
Update, 7/23/2016 5:42 PM EST :
I tried to use <apex:outputLabel /> as suggested by Santanu below, but to no avail.
When I tried <apex:outputLabel value="{!field}" />, the resulting label was displaying the API names for the fields.
When I tried <apex:outputLabel value="{!Opportunity[field]}" />, the resulting label was displaying the value of each field in the fieldSet (showing 1.65% instead of showing "Transaction Fee")
I then tried just manually creating an inputField directly below the PageBlockSection, as it was suggested that inputFields only show BOTH the label and value if they are directly below (not in a repeat). This also resulted in just the field value (with no label) even when using the standard Opportunity controller and standard Name field (shown below):
<apex:pageBlockSection columns="1" id="rateCalc" title="Rate Calculator" rendered="true" >
<apex:form >
<apex:inputField value="{!Opportunity.Name}" />
