This error occurs mostly when the Correlation Token values has been not set properly for activities.

Correlation token– A correlation token is essentially a means of uniquely identifying each instance of a workflow, modification or task.

OnWorkflowActivated, OnWorkflowItemChanged,OnWorkflowItemDeleted, SetState, SendEmail and UpdateAllTasks these activities should be using same workflow token for e.g. workflowToken.

CreateTask, CreateTaskWithContentType,UpdateTask, DeleteTask, CompleteTask,RollbackTask, OnTaskChanged, OnTaskDeleted, OnTaskCreated these activites should be using same correlation token for e.g. taskToken.

EnableWorkflowModification, OnWorkflowModified should be sharing same correlation token for e.g. modificationToken.

Each distinct task or modification would be having it own distinct token.

I have developed certain workflows using SharePoint designer, everything was working fine. Than suddenly an issue started to show up i.e whenever i was making a modification in the workflow it was not getting reflected back on the site, until i found the solution for it.

These errors occur if the InfoPath form haven’t been published properly.

Always make sure that you have followed the below steps mentioned in the document while publishing the InfoPath form within SharePoint workflow

It may be because the security level would be set as Full Trust, which requires the form to be digitally signed. Change the security level to Domain.

Go To Tools àForm Option àSecurity and Trust to change the security level.

Using JavaScript

First find out the tag corresponding to the input field which would like to set as read only

For this open up the editform.aspx page right click it and select view source

Say this is the tag of the input field

<input name=”TextField” type=”text” value=”Approved” maxlength=”255″ id=”4_ctl00_ctl00_TextField” title=”Status of Idea” class=”ms-long” />

Now open your editform.aspx page in SharePoint designer and add the following script to it

<script type=”text/javascript”>

function SetReadOnly()

{

// find all the elements with tag Name as INPUT

var elements=document.body.getElementsByTagName(“INPUT”);

// loop through all the elements till we find an element with type text and title as name of our field

for (index=0; index < elements.length;++index)

{

if(elements[index].type==“text”)

{

if(elements[index].title==“Status of Idea”)

{

elements[index].readOnly=true;

}

}

}

}

_spBodyOnLoadFunctionNames.push(“SetReadOnly()”);

</script>

Or

<script type=”text/javascript”>

function SetReadOnly()

{

var elements=document.getElementById(‘4_ctl00_ctl00_TextField’);

elements.readOnly=true;

}

_spBodyOnLoadFunctionNames.push(“SetReadOnly()”);

</script>

Or using event handler as mentioned over here

Or

Using CAML

And to hide button say OK button than

function SetHidden()
{
alert(‘Hi’);
var x=document.getElementsByTagName(“input”);
for (var i=0;i<x.length;i++)
{
if (x.item(i).type==”button”&&x.item(i).value==”OK”)
{
x.item(i).style.display = “none”
};
}
}
_spBodyOnLoadFunctionNames.push(“SetHidden()”);
