WorkFlow Event Reveiver parameter "properties.ActivationProperties" is null.

I have a Workflow that is using an InfoPath task form.  In the "FormEvents_Loading" method event handler I have some code that needs to run each time the form is opened.   I recycle the App Pool and open the form the code runs perfectly, but if I close and try to re-open the form the code is not run at all.  I can then recycle the App Pool again and on the next load the code executes just fine.   The code that is supposed to be run is a very simple statement to set a field value, so I don't think it is interfering.

Does anyone know what this might be?

Thanks,

Is there any way to modify the sample Workflow Monitor class so the user can interact with the diagram, for example;    1) being able to select an activity in the diagram and get back an event of which activity was selected? and/or 2) being able to trigger an if else branch by clicking on the diagram. Any pointers to howtos/tutorials will be helpful, thanks!

Hello everybody,I faced a very weird behavior while creating a workflow in SPD against a Document Library.Here is the case:1- Create a document library in sharepoint site.2- Add a custom column of type DATE.3- Upload any document to the library4- Edit the item metadata and set the custom date field to any date you want.5- Now using sharepoint designer, create a very simple Workflow with only one action that updates the current item "Title" field to any value. (Note: In my case I set the workflow to start manually and not automatically)6- Save the workflow and then start it on the uploaded item.7- Now check the value of the date column after the workflow is finished.8- You will see that the Date field is Empty... (very weird)Notes:   1-This behavior will not appear on a standard list. it is only appearing in a Document library.  2- I am using WSS 3.0 SP2 + MOSS 2007 SP2. Also SharePoint designer 2007 SP2Did anyone face this situation and does it have a fix, or am I doing something wrong here... Please help.Regards,Maheed

I have an activity that has properties that look something like this (they're set up as proper dependency properties, I just kept it simple here): public List<MyType> TypeList { get; set; }public Int32 Index { get; set; }public MyType SelectedType { get; set; } and an execution that just does this: SelectedType = TypeList[Index]; TypeList and Index are values that I set from other activities. I don't set SelectedType to anything in the activity properties, I just let it get set in the execution. Now I know for a fact that SelectedType is getting set properly, I can even point another activity to it and print out some values from it. So I'm quite positive that there's nothing wrong with that activity. However, I have an if activity with a condition that looks like this: ((MyActivity)GetActivityByName("activity1")).SelectedType != null and it evaluates to false (meaning it evaluated SelectedType as null). I'm pretty sure that that activity cast is correct (I do things like that all the time), and if it weren't wouldn't I get a null reference exception when trying to access SelectedType? So I'm pretty sure I'm not doing anything wrong here, but for some reason SelectedType is coming up null in that condition and no where else. It's almost as if the condition is being evaluated before the activity is being run, but the activity comes well before the condi

HiI'm trying to retreive values entered by users in the textboxes in the footer of the gridview and insert these values into another sql table.My code is as follows :-protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)    {       if(e.CommandName.Equals("addnew"))       {                       TextBox t1 = (TextBox)GridView2.FooterRow.FindControl("tfrm");            string frm = t1.Text;            TextBox t2 = (TextBox)GridView2.FooterRow.FindControl("tsub");            string sub = t2.Text;            string cmd = "insert into suggestions values('" + frm + "','" + sub + "','c','c')";            con.Open();            SqlCommand com = new SqlCommand(cmd,con);            int a = com.ExecuteNonQuery();&n

Hi, I am using SSRS 2005 SP3. I have the following query that I use for my parameter: SELECT 0 AS c1, 'NOT Specified' AS c2 UNION SELECT 1 AS c1, NULL AS c2 UNION SELECT 2 AS c1, 'Test 1' AS c2 UNION SELECT 3 AS c1, 'Test 2' AS c2 Let's call my parameter prm1. The type of prm1 is string and it has "Allow null value" and "Allow blank value" options ticked. C1 is the value field and C2 is the label field for prm1. When I preview the report, and I didn't see NULL in my drop down list,  but that record has been shown as 1 (which is the value). I am wondering if this is a normal behavior of SSRS? It's not a big deal. I can replace NULL with something else, but I am just curious. Cheers, Uzzie

WorkflowRuntime workflowRuntime = new WorkflowRuntime(); ExternalDataExchangeService dataExchangeService; dataExchangeService = new ExternalDataExchangeService(); workflowRuntime.AddService(dataExchangeService); PaymentProcessingService paymentProcessing; paymentProcessing = new PaymentProcessingService(); dataExchangeService.AddService(paymentProcessing); With the code above, our application can use paymentProcessing.RaiseXXXXEvent to interactive with the workflow instance. My question is : What's the principle to implement such a mechanism. I think this is a kind of Event Driven Pattern, but how can I implement this mechanism and why ? Please point me the direction or any references are appreciated. By the way, is there the mechanism in jBPM ? Does jBPM include sequence workflow and state machine workflow like window workflow foundation ? Thanks ! Dummy

Hello, I'm have customized my homepage in SharePoint Designer 2010. I want to go back to a previous version, so I right click on the aspx file in sharepoint designer and choose "version history". When I do that I get this message: There was an error connecting to the server. The server error encountered is "Value cannot be null. Parameter name: key" What should I do in order to revert my aspx page to a previous version ?

I am using a hosted workflow designer to allow users to create their workflows. I would like them to be able to execute the workflow in a 'Test' mode, so I am trying to pass a parameter that indicates it is test mode.

In addition to the workflow being run from the rehosted designer, it will also be getting executed by an automated Workflow Console Application. So when the workflow is executed from the rehosted designer, it should execute in test mode. When it is executed from the console application, it should execute in production mode.

I thought I would just be able to pass a paramter indicating which mode to run it in, but the only way I can seem to get it to work is to have an Activity already on the workflow and setup the Argument for them through the designer and assign the expression prior to run time. The problem is that the user starts out with a blank workflow with no activities on it. I do not know which activity the user is going to add to the workflow, and I don't want them to have to be able to figure out how to configure arguments. It is an argument that should just always be there.

All the activities that I've made available to the user are inherited from a base class which inherits from NativeActivity. So is there anyway to dynamically bind the activities to the argument passed in at runtime in the base class?

I have a vb.net page that has an optional parameter.   If a user enters data for that field, and clicks save, it saves fine via the stored procedure.  HOWEVER, if the user changes their mind, and wants to erase the data they entered, they go to the text field, and delete the characters, and click save, but no matter what, the stored procedure will not save the fact that they erased the data (it won't set it back to NULL).  If the user enters a space, the stored procedure will save the space, and if they enter different data, it will save the other data.  I can't figure out how to get it back to letting them set it to Null?      I think this is because it's an optional parameter, and the stored proc is used by several forms (Some of those forms do not include this parameter), but this form utilizes that optional paramater. 

Here's my stored procedure...

CREATE PROCEDURE [dbo].[123456]
@hdnMatterID int,
@BillingArrangementID int,
@BillingArrangementDetails varchar(200) = NULL,   -----This is the parameter that can't seem to get set back to null if a user changes their mind and tries to erase the stored data...
@BillingFrequencyID int
@BillingID

AS
BEGIN


UPDATE  t123456

SET BillingArrangementID = @BillingArrang
