[SalesForce] Display controller variable on VF page. How

I am trying to show 3 consecutive "blocks/span", 2 are variables, 3rd is a button.

Links to : 1. the element 2. the controller

WITH the last button element, the page DOES NOT save, the error given is :

Error: Could not resolve the entity from <apex:outputField> value binding '{!totalGoodBC}'. <apex:outputField> can only be used with SObjects, or objects that are Visualforce field component resolvable.

WITHOUT the button, the page SAVES, the error is :

value for <apex:outputField> is not a dynamic binding

What is going on here?

In this scenario, you should use <apex:outputText> instead of <apex:outputField>.

<apex:outputText value="{!totalGoodBC}" styleClass="slds-input"/>

<apex:outputField>is used to bind values which are of Sobject type. Or in other words, instance of Sobject class.

[SalesForce] apex:inputField can only be used with sObjects

The apex:inputField value u.contact must correspond to an SObject field. That is typically done by u being a reference to an SObject and contact being an SObject field name. For your example, that SObject field would be lookup field to Contact.

apex:inputField requires meta data such as the field label that is only available from an SObject field; your class field can't provide that metadata.

Try changing your Visualforce to:

<apex:column headerValue="Contact">
    <apex:inputField value="{!u.contact.Id}" />
</apex:column>
<apex:column headerValue="Role">
    <apex:inputText value="{!u.role}" />
</apex:column>

[SalesForce] Apex InputField value binding error

I think there are two issues:

apex:inputField can only bind to an SObject field (as it takes the type and label from the field metadata) but you are trying to bind it to a String; use apex:inputText instead
you have not provided get/set methods for OrderItem.test; one way to accomplish this is to change the code to initialise in the constructor and then use a public String test {get; set;} Apex Property
