Hi Chris,

thanks for this fantastic blog! I tried this in my developeraccount, but without access. Here is my class:

global class BatchProcessDemo {
webservice static void processItems() {
Integer queryLimit = (Limits.getLimitQueryRows() - Limits.getQueryRows()) / 2;
for (List<Account> sourceItemList :[select Id, Name
from Account
where Processed__c = false
limit :queryLimit ]) {
List<MyAccount__c> itemsToInsert = new List<MyAccount__c>();
for (Account sourceItem : sourceItemList) {
sourceItem.Processed__c = true;
MyAccount__c targetItem = new MyAccount__c();
targetItem.Account__c = sourceItem.Id;
if (Limits.getDMLRows() + itemsToInsert.size() + 1 >= Limits.getLimitDMLRows()) {
insert itemsToInsert;
}
itemsToInsert.add(targetItem);
}
update sourceItemList;
insert itemsToInsert;
}
}
}

and my Visualforcepage:

<apex:page >
<script language="javascript">
function batchProcess(){
var iterations = document.getElementById("iterations").value;
var progress = document.getElementById("progress");
progress.innerHTML = "Processing iteration 1 of " + iterations + " iterations.";
sforce.connection.sessionId = "{!$Api.Session_ID}"; //to avoid session timeout
for (i=1; i <= iterations; i++) {
progress.innerHTML = "Processing new iteration " + i + " of " + iterations + " iterations.";
sforce.apex.execute("BatchProcessDemo","processItems ",{});
}
progress.innerHTML = "Completed processing " + iterations + " iterations!";
}
</script>

<apex:sectionHeader title="Demo"/>
<apex:form >
<apex:pageBlock title="Perform Batch Process">
<apex:panelGrid columns="2" id="theGrid">
<apex:outputLabel value="Max. # of Iterations"/>
<input type="text" value="1" name="iterations" id="iterations"/>
</apex:panelGrid>
<div id="progress" style="color: red"/>
<apex:pageBlockButtons >
<input type="button" onclick="batchProcess()" value="Start" class="btn"/>
</apex:pageBlockButtons>
</apex:pageBlock>
</apex:form>
</apex:page>

So I put in a value (like 5), push the start button. I can see the first processvalue:
Processing iteration 1 of 5 iterations.

But nothing happens anymore. Do you have an Idea why it isn't working?
