Hello,

i've created a VF page using

Example Code for In-Place Editing in Visualforce

for adding new items to Opportunity Inventory (Move_Inventory_Item__c is a custom object),

and it works fine if there are already Inventory Items added to this Opportunity, but if you try to add a first Item, page just does not do anything. Can anybody see what is wrong here? - thank you very much.

Here is the page:

<apex:page sidebar="false" controller="MoveInventoryController" tabStyle="Inventory_Item__c" action="{!init}" >
<style>
  .alphaOn{font-weight:bold;text-decoration:none;}
  .bPageBlock .pbTitle {width:100%;}
  .bPageTitle {margin-bottom:5px;}
  </style>
<apex:sectionHeader title="Manage Move Inventory" subtitle="{!Opp.Name}"/>
    <apex:outputPanel ><apex:outputLink value="/{!Opp.Id}">« Return to Opportunity</apex:outputLink></apex:outputPanel>
    <apex:pageMessages />
    <apex:form >
    <apex:pageBlock title="Add Non-Standard Inventory Item">
        Name:   <apex:inputField value="{!newItem.Name}"/>
        Size:   <apex:inputField value="{!newItem.Size__c}"/>  
        Weight:   <apex:inputField value="{!newItem.Weight__c}"/>
        Quantity:   <apex:inputField value="{!newItem.Quantity__c}"/>  
        <apex:commandButton value="Add" action="{!add}"/>
    </apex:pageBlock>
    </apex:form>
    <apex:form >
    <apex:pageBlock title="Existing Opportunity Inventory Items  - {!Opp.Volume2__c} cubic feet, {!Opp.Weight__c} lbs" id="inventoryTitle">
