[SalesForce] Error: Could not resolve the entity from value binding – VF Component

UPDATED:

The below answer was incomplete and here is the complete answer to my question:

If you really want an Sobject type declare attribute as an sobject

<apex:attribute name="CaseNumber" description="Case Number" type="<name_of_your_object>" required="true"/>

<apex:inputField id="cn" value="{!CaseNumber.<field_name>}"/>

Hope this will help others.

I'm creating a VF Component page and I'm not sure why I'm getting this error:

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

<apex:component>

    <apex:attribute name="CaseNumber" description="Case Number" type="String" required="true"/>    

 <apex:pageBlockSection title="Item Detail " columns="1" showHeader="true" > 
      <apex:outputPanel layout="none">
       <table class="list" border="0" cellpadding="0" cellspacing="0"  >
         <tr >
           <td>Case Number</td>
           <td style="text-align:left;"><apex:inputField id="cn" value="{!CaseNumber}"/></td>
         </tr>
       </table>
 </apex:outputPanel>
</apex:pageBlockSection>

</apex:component>

Best Answer

The problem here is you are using apex:inputField that requires an Sobject .

If your attribute type is String just use apex:inputText instead

<apex:inputText id="cn" value="{!CaseNumber}"/>

If you really want an Sobject type declare attribute as an sobject

<apex:attribute name="CaseNumber" description="Case Number" type="Case" required="true"/>

[SalesForce] value for is not a dynamic binding!

Your <apex:inputfield> is missing value attribute, set the value for the inputfield like <apex:inputfield value = "{!instanceOfSObject.Field}">.

Value of for inputfield is A merge field that references the Salesforce field that is associated with this inputField. For example, if you want to display an input field for an account's name field, use value="{!account.name}". You can't associate this inputField with a formula merge field of type currency if your organization is using dated exchange rates.

[SalesForce] apex:inputField not binding value to controller

You have multiple forms on your page. You button is in a separate form so when you submit it does not grab the value from the input fields in the other form.

Wrap you entire code in the form as follows:

<div class="portlet-body">
    <apex:form styleClass="form-horizontal" html-role="form">
        <div class="form-body">
            <img src="https://allizancespecializedsytems--emorandev.cs2.my.salesforce.com/img/social/unknown_company_pic.png"/>
            <h2 class="margin-bottom-20">{!Account.Name} </h2>
                <div class="row">
                    <!--/span-->
                    <div class="col-md-6">
                        <div class="form-group">
                            <label class="control-label col-md-3">Nombre:</label>
                            <div class="col-md-9">
                                <apex:inputField value="{!account.Name}" styleClass="form-control"/>
                                <!--Trying to change this value but is never updated-->
                            </div>
                        </div>
                    </div>
                </div>
        </div>
        <div class="form-actions">
                <div class="row">
                    <div class="col-md-6">
                        <div class="row">
                            <div class="col-md-offset-3 col-md-9">
                                <apex:commandButton value="Guardar" action="{!updateRecord}" styleClass="btn green"/>
                                <a href="/apex/CustomerPortalAccounts?Id={!account.Id}" class="btn default" role="button">Cancelar</a>
                            </div>
                        </div>
                    </div>
                    <div class="col-md-6"> </div>
                </div>
        </div>
    </apex:form>
</div>

Note: I also removed your html form tag. Not sure of the top of my head if the apex:form allows html passthrough attributes.
