Contact Selector Failed in MOSS Workflow Modification Infopath Form

Posted By:      Posted Date: September 02, 2010    Points: 0   Category :SharePoint
Hi,   In my proof of concept Moss 2007 WF, I tested an Infopath modification form successfully.  Then the contact selector ActiveX control was added but it failed to open using the modification link of the workflow page.  In a different form for the WF initiation, I similarly created two CS controls and it worked there.  A snippet of the MOSS error is below   Object reference not set to an instance of an object.   at Microsoft.Office.InfoPath.Server.Controls.ContactPicker.RenderClientViewDataLeafContent(XPathNavigator context, IRenderContext renderContext, ControlViewData controlViewData, ScriptWriter writer)    at Microsoft.Office.InfoPath.Server.Controls.LeafControl.RenderClientViewDataContent(XPathNavigator context, IRenderContext renderContext, ScriptWriter writer)    at Microsoft.Office.InfoPath.Server.Controls.BaseControl.RenderClientViewData(XPathNavigator context, IRenderContext renderContext, ScriptWriter writer)    at Microsoft.Office.InfoPath.Server.Controls.ContainerControl.RenderClientViewDataContent(XPathNavigator context, IRenderContext renderContext, ScriptWriter writer)    at Microsoft.Office.InfoPath.Server.Controls.BaseControl.RenderClientViewData(XPathNavigator context, IRenderContext renderContext, ScriptWriter writer)    at Microsoft.Office.InfoPath.Server.Controls.CollectionControl.RenderClientViewDataContent(XPathNavigator context, IRenderContext rend

SharePoint Designer workflow task - problem with multiple users selector in InfoPath form




I have got an issue with InfoPath form generated for my SharePoint Designer workflow task. There is a multiple users selector that requests users from a task assignee. The problem is that only the first user entered got saved.


I am using SharePoint 2010 Standard Server (release). Steps to reproduce are the following:

Using Infopath form fieldnames in a workflow fails



I designed a form in Infopath and I published it on a SP2007 server to use in a workflow in a library. That goes fine. In the workflow I send an email message. I can use the fields from my Infopath form in the message that I create. 
If the workfow is starts, Shrepoints sends me the message. But it does not use the fields from my InfoPtah form in the message in stead I see questionmarks.

Why doesn't it show the fields?

I alse saw (maybe this makes it clear) that when I let it dipslay the URL in the message, it show: http://1.portal.lucasonderwijs, but the actual site is whithout the "1" and it should also start with https://

Has anyone seen this before?

Thank you,


InfoPath Workflow Task Form "Loading" event handler only being called after App Pool recycled.


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?


InfoPath form checked out so 'on create' workflow not being started


Hi all,


I have found a couple of threads asking for advice on how to check in an InfoPath form when it’s saved or submitted to a forms library. The reason for doing this is so a workflow can start based on a new item being created in that library, and so it doesn’t just sit there with a “Starting” status.


The answers I have found contradict each other:

·         You have to do it with a workflow.  This can be done easily with SharePoint Designer if that's an option for you. Source:

Contact Selector - Form tab index is lost after selector resolves names on blur


I'm working with an InfoPath2007 form developed to be filled-out through the browser on a SharePoint 2007 site, and I'm testing using Internet Explorer 7.  It's a straight-forward form, with a number of text fields and two Contact Selector controls.

The issue I'm encountering is with the Contact Selector control, where if the actor only enters a partial name into the text-field and then TABs away from the control the form will perform its auto-postback to look-up and resolve the partial name (showing the name resolution dialog is necessary), and afterward the actor's cursor is focused on the next field in the form.  The actor can type text into the focused field, but any subsequent pressing of the TAB key returns the actor's focus to the browser's ADDRESS bar, which is incorrect as it should proceed to the next field in the form.  I understand that the Contact Selector needs to perform its postback to perform the name resolution (so that there is no way through the InfoPath form designer to disable postbacks for the control), but why does the browser not know how to continue the TAB order of the fields on the form even when a field has focus?

Workflow which is activated when infopath form created but need attached to another costing form als


I have a requirement to create an infopath form which is simple enough to create and is pretty much done.

It however has a secret which they didn't really mention in the doc or their "simple workflow requriemetns" and this is  that it goes some where for costing.

The idea of this is to automate a paper trail so I am thinking that this costing which is to be attached to this document should not simple be an upload onto the form but part of the workflow tasks.

My questions are.

If I have the follow workflow requiremetns.


1. User fill in form and submit

2. workflow then starts

3. (cost part next?) one group of people liase with accountants to ensure funding is posible and attach to form. two option I see here.

opt 1

The costing part is part of the workflow but if I do this I need the field to be read only for everyone except for a couple of groups is it possible in infopath to do this?

Opt 2

The costing is in a different library which the workflow create the new file this has it own workflow with a task to complete it and when completed workflow marks a field as complete before the main workflow will move on to next steps.

I would need to link the two forms together preferably in both directions would be nice what the best way to do this?

4 Once costing is co

Workflow doesn't complete when a task is updated directly from an infopath form.

I have an approval workflow that creates a task for a group to approve or reject an InfoPath form. But if a member of the group opens the form and updates the task from there, it doesn't complete the workflow. It only completes the workflow if they go to the actual task and update it from there. Does anyone know how to fix that?

Automatically populating Contact Selector not working in Form Services

Hi,I'm currently working on a form where i wan't to automatically populate a contact selector control with a users manager. I've got the managers userid, called the ResolvePrincipal webservice provided by sharpoint, and set all the values in the contact selector with the correct values. When previewing it works perfectly however when i move the form to Form Services it won't work.I've tried setting it via rules: i.e. on the change of a textbox write the manager values to the contact selector.I've tried setting the default values of the contact selector to fields where i write the manager values.I've tried setting it through code i.e. SelectSingleNode() and SetValue() for each of the fields in the contact selector.All of which work fine in preview mode but will not work in Form Services, UNLESS the contact selector already has a user in it. So if the contact selector is blank it won't work, however as soon as i manually select a user then try using any of the previously mentioned methods of setting the control it works. While using code i get a nullreferenceexception which leads me to think that possibly when theres no user in the control the xml nodes representing the AccountId, DisplayName, AccountType don't exit???? TO throw another spanner in the works, on the very odd occasion it will work in Form Services as expected, after celebrating and trying again it returns

What are the Steps Installing Infopath Form Service on WSS 3.0 or do I need to upgrade to MOSS?

I  have configured Extranet Https Portal for our configuration.It includes some custom web-parts features in the site. My WSS 3.0 -Cenrtal Admin version is I have MOSS 2007 - Central Version Now I have designed a Infoapth form and want to publish to a library in the site.We can publish the form to a library but At client side Infopath 2007 sholud be installed in order to submit the form.It is not Browser Enabled. ( You cannot enable InfoPath Forms Services in WSS, because it is not present in WSS. Before you can enable InfoPath Forms Services, you have to install Forms Server or MOSS Enterprise.  It is not Browser enabled.  ) Infopath form services is a component of MOSS not WSS Is there any other way instead of intalling Moss 2007 can I only Install Infoapth Form services on it. Can I upgrade the WSS 3.0 to MOSS 2007 and get the Infoapth form services to the existing site without any loss of data.   I have read that while upgrading wss to moss the central admin version  should be same then only you can upgrade is this true?? what steps I need to consider ?? Guide me Thanks in Advance Harish

Book to learn and Develop enterprise application using InfoPath with workflow in MOSS 2007

Hi all, I'm new to infopath forms and i dont find much articles to develop enterprise application (I'm coding for an ERP module).

Associating an InfoPath form as an initiation form of a workflow, and have it appear when workflow i

Hi all,   I've been working with and infopath form which I want to integrate into my Visual Studio 2008 SharePoint Workflow. I have done all the steps and can verify that the form works as it should, because if I associate the workflow and allow it to be kicked off manually, the form displays if i kick the workflow off... However, if I set the trigger to be "Start workflow when an new item is created", the form does not display and it goes straight into the code... why does my form not display when the workflow is triggered from a new item, but does if the item already exists??  Is there a way to get around it so that the form does show when a new item is created please?   Thanks, Ben
