I'm trying to pass value for <apex:inputField> to wrapper class, but it doesn't work. The form does show the data from wrapper class which I think the get() is working but not the set(). I have turned on debug log and none of the changes (on the input field) has been passed on to the controller. Could someone point out where the problem is?

VF page:

<apex:pageBlockSection title="Meal Options" columns="1">

Hi, I'm trying to create an Onclick JavaScript custom button (as List Button for multi-record action) and hitting below error:

"sObject type 'sObject' is not supported. If you are attempting to use a custom object, be sure to append the '__c' after the entity name. Please reference your WSDL or the describe call for the appropriate names."

This button is put on Account object's related list and the target object is filepicker__File__c which is from managed package. When I select filepicker__File__c records from Account's related list view, and click this custom button, it shows above error.

Below is my JavaScript:
{!REQUIRESCRIPT("/soap/ajax/31.0/connection.js")}
var records = {!GETRECORDIDS($ObjectType.filepicker__File__c)};
var files = [];
if (records.length == 0) {
   alert("Please select at least one record to update.");     
} else {
      for (var a=0; a<records.length; a++) {
         var file = new sforce.SObject("filepicker__File__c");
         file.filepicker__id = records[a].filepicker__id;
         file.filepicker__AU_Access__c = "Yes";
         files.push(file);
      }
      result = sforce.connection.update([files]);  

if (result[0].success == 'false') {
alert(result[0].errors.message);
}
else {
location.reload(true); /* redisplay the detail page */
}
  }

Can someone help find out the cause? Thank you!

        </section>
    </div>

And below is campingListItem.cmp:

<aura:component>
    <aura:attribute name="item" type="Camping_Item__c"/>
    <p>Name:
        <ui:outputText value="{!v.item.name}"/>
    </p>
    <p>Price:
        <ui:outputCurrency value="{!v.item.Price__c}"/>
    </p>
    <p>Quanity:
        <ui:outputNumber value="{!v.item.Quantity__c}"/>
    </p>
    <p>Packed:
        <ui:outputCheckbox value="{!v.item.Packed__c}"/>
    </p>
</aura:component>

I can see the error happens in below code within campingList.cmp:

<aura:iteration items="{!v.items}" var="item">
                    <c:campingListItem item="{!item}"/>
                </aura:iteration>

And once I replace it with below code, the error doesn't happen any more. Can someone help check what's wrong with my nest component code. Thanks!

<aura:iteration items="{!v.items}" var="item">
                     <aura:attribute name="item" type="Camping_Item__c"/>
                     <p>Name:
                         <ui:outputText value="{!item.name}"/>
                     </p>
                     <p>Price:
                         <ui:outputCurrency value="{!item.Price__c}"/>
                     </p>
                     <p>Quanity:
                         <ui:outputNumber value="{!item.Quantity__c}"/>
                     </p>
                     <p>Packed:
                         <ui:outputCheckbox value="{!item.Packed__c}"/>
                     </p>
                 </aura:iteration>

Hi, I'm trying to create an Onclick JavaScript custom button (as List Button for multi-record action) and hitting below error:

"sObject type 'sObject' is not supported. If you are attempting to use a custom object, be sure to append the '__c' after the entity name. Please reference your WSDL or the describe call for the appropriate names."

This button is put on Account object's related list and the target object is filepicker__File__c which is from managed package. When I select filepicker__File__c records from Account's related list view, and click this custom button, it shows above error.

Below is my JavaScript:
{!REQUIRESCRIPT("/soap/ajax/31.0/connection.js")}
var records = {!GETRECORDIDS($ObjectType.filepicker__File__c)};
var files = [];
if (records.length == 0) {
   alert("Please select at least one record to update.");     
} else {
      for (var a=0; a<records.length; a++) {
         var file = new sforce.SObject("filepicker__File__c");
         file.filepicker__id = records[a].filepicker__id;
         file.filepicker__AU_Access__c = "Yes";
         files.push(file);
      }
      result = sforce.connection.update([files]);  

if (result[0].success == 'false') {
alert(result[0].errors.message);
}
else {
location.reload(true); /* redisplay the detail page */
}
  }

Can someone help find out the cause? Thank you!
