Help using rendered in VF page

Question

I have a visual force page, on my custom object Visit_Plan__c, looked like this

And my custom object relation : (Parent -> Child) Master_Visit_Plan__c -> Master_Visit_Plan_Branch__c -> Visit_Plan_Header__c -> Visit_Plan

I want to make billing account inputfield disappear if the Master_Visit_Plan__c Entitas_New_Field__c = 'Pusat'.

I tried to use IF inside the rendered

<apex:column headerValue="Billing Account">
               <apex:inputfield value="{!var.vp2.Billing_Account__c}" rendered="{!IF(var.vp2.Visit_Plan_Header__r.Master_Visit_Plan_Branch__r.Master_Visit_Plan__r.Entitas_New__c='Pusat',false,true)}"/>
               </apex:column>

But seems like the if condition didnt met.. because even if my Master_Visit_Plan__c entitas_new__c field != 'pusat' (Else), the billing account inputfield disappear too

Answer 1

You don't need to use an IF statement here, because = in an expression already returns a Boolean value:

rendered="{!var.vp2.Visit_Plan_Header__r.Master_Visit_Plan_Branch__r.Master_Visit_Plan__r.Entitas_New__c='Pusat'}"

As Adrian stated, you always need to put the value_when_true value before the value_when_false value, but it's simply more efficient to use Boolean values directly, when possible.

Edit:

If you want to invert the value, you can just use not-equals instead:

rendered="{!var.vp2.Visit_Plan_Header__r.Master_Visit_Plan_Branch__r.Master_Visit_Plan__r.Entitas_New__c!='Pusat'}"

Answer 2

This is simple condition and it's not mandatory to use if condition for this.

If you are still facing issue, check with value what you are receiving in page side.

Just put below debug log after Apex: column and check in inspect element -> Console tab.

console.log("debug"+{!var.vp2.Visit_Plan_Header__r.Master_Visit_Plan_Branch__r.Master_Visit_Plan__r.Entitas_New__c});
