Hi,
I am trying to generate unique AccountName via WF and having issues in EnumeratedResourceActivity. Eventhough I set up XPathFilter property the error message says the filter is empty(or not set). Here is the visual of my WF.
So when a user is created with email let's say xyz@google.com I am trying to add AccountName to the user request here. If the user name is already present in portal I am appending 1 then 2 then 3 and so on.
here is my logic
public const string WF_ACTOR_GUID = "3f862651-ebee-4cf8-a824-0c9663757aCC";
public int loopCounter = 1;
public bool loopAgain = true;
public string _accountName;
public string _email;
public AddUniqueAccountName()
{
InitializeComponent();
}
public string AccountName
{
get { return _accountName; }
set { _accountName = value; }
}
public string Email
{
get { return _email; }
set { _email = value; }
}
private void InitializeReadResource_ExecuteCode(object sender, EventArgs e)
{
this.readResourceActivity1.ActorId = new System.Guid(WF_ACTOR_GUID);
this.readResourceActivity1.ResourceId = this.CurrentRequestActivity1_CurrentRequest1.Target.GetGuid();
}
private void GenerateUniqueAccountName_ExecuteCode(object sender, EventArgs e)
{
this.readResourceActivity1.SelectionAttributes = new string[] { "AccountName", "Email" };
ResourceType user = readResourceActivity1.Resource;
this.Email = (string)user["Email"];
this.AccountName = getAccountName();
}
private void InitializeEnumerateResource_ExecuteCode(object sender, EventArgs e)
{
this.enumerateResourcesActivity1.ActorId = new System.Guid(WF_ACTOR_GUID);
String resourceType = this.readResourceActivity1_Resource1["ObjectType"].ToString();
this.enumerateResourcesActivity1.Selection = new string[] { "AccountName" };
this.enumerateResourcesActivity1.XPathFilter = "/" + resourceType + "[AccountName =\'" + this.AccountName + "\']"; // /Person[AccountName='patelb']
}
private void CheckUniqueness_ExecuteCode(object sender, EventArgs e)
{
int totalcount = this.enumerateResourcesActivity1.TotalResultsCount;
ResourceType results = EnumerateResourcesActivity.GetCurrentIterationItem((CodeActivity)sender) as ResourceType;
if (totalcount > 0)
{
this.AccountName = this.AccountName + loopCounter.ToString();
this.loopAgain = true;
}
else
this.loopAgain = false;
}
private void InitializeUpdateTarget_ExecuteCode(object sender, EventArgs e)
{

this.UpdateResourceActivity1.UpdateParameters[0] = new UpdateRequestParameter("AccountName", UpdateMode.Modify, this.AccountName);

I am NOT sure what I am doing wrong here. I also read when you use EnumerateResource you may not want to use while loop but I am not sure how we can enumerate results once you get from EnumerateResourceActivity.
I would really appreciate you if you suggest any solution/better approach to this.
Thanks,
