People Picker field and Web service -- multiple round trips to get Display Name value

Using Sharepoint 2010 and Infopath 2010, I have created a form that validates fields entered within the form by connecting to a .Net web service created by someone else. One of the fields that I need to validate is a People Picker field
for the Project Manager.
The connection to the Web Service runs correctly except that the People Picker goes through the validation process 3-4 times. I know this because I have a MessageBox showing the value for the InnerXML that pops up 3 times. The
first time the MessageBox shows no value for the XML, the next time it shows a name, and the 3rd time it shows no value.
Here is the code I'm using in the Infopath form (without the Messagebox):
Dim wsConnection As WebServiceConnection = DirectCast(Me.DataConnections("Validate"), WebServiceConnection)
Dim formNavigatorProjectManager As XPathNavigator = MainDataSource.CreateNavigator()
Dim wsNavigatorProjectManager As XPathNavigator = Me.DataSources("Validate").CreateNavigator()
strformNavProjectManager = formNavigatorProjectManager.SelectSingleNode("/pr:properties/p:properties/documentManagement/ns3:ProjectManager/ns3:UserInfo/ns3:DisplayName", NamespaceManager).InnerXml
wsNavigatorProjectManager.SelectSingleNode("/dfs:myFields/dfs:queryFields/ns7:Validate/ns7:projectManager", NamespaceManager).SetValue(strformNavProjectManager)
wsConnection.Execute()
The line in BOLD above used to have just /pr:properties/p:properties/documentManagement/ns3:ProjectManager
but I thought my problem might be because People Picker fields are made up of 3 elements -- DisplayName, AccountID and Account Type. So I changed the XML. Sadly, that didn't make any difference.
I am using the CHANGED event which a colleague of mine thought would have taken care of the multiple round trips. But it didn't.
Hopefully someone out there can tell me what I need to do so that this People Picker field only get validated once (The form also has Managed Metadata fields that have very similar problems so I'm hoping that the solution for the People Picker field
takes care of the MMD fields too.) Thanks in advance. Carol.

Hi Carol,
It is the behavior for setting People/Group field if you just select the node "/dfs:myFields/dfs:queryFields/ns7:Validate/ns7:projectManager".
Also you can try to only set the AccountID value of the People/Group field:
Dim wsConnection As WebServiceConnection = DirectCast(Me.DataConnections("Validate"), WebServiceConnection)
Dim formNavigatorProjectManager As XPathNavigator = MainDataSource.CreateNavigator()
Dim wsNavigatorProjectManager As XPathNavigator = Me.DataSources("Validate").CreateNavigator()
strformNavProjectManagerID = formNavigatorProjectManager.SelectSingleNode("/pr:properties/p:properties/documentManagement/ns3:ProjectManager/ns3:UserInfo/ns3:AccountID", NamespaceManager).InnerXml
wsNavigatorProjectManager.SelectSingleNode("/dfs:myFields/dfs:queryFields/ns7:Validate/ns7:projectManager/ns7:userinfo/ns7:AccountID", NamespaceManager).SetValue(strformNavProjectManagerID)
wsConnection.Execute()
Thanks,
Eric

When I enter a group name into the Bcc field and try to send the message, I get "[group name] is not a valid e-mail address..."

Been using the same template to send a weekly newsletter for a year or two but now with a recent update to Thunderbird the group name is rejected when I try to send the message:
With a group name in Bcc field, when I press "Send" and try to send the message, I get this alert: "[group name] is not a valid e-mail address because it is not of the form user@host. You must correct it before sending the e-mail."

This has been reported as [https://bugzilla.mozilla.org/show_bug.cgi?id=1060901 Bug #1060901]. If you have an account on Bugzilla, please consider voting for that issue.

Although not ideal, these workarounds should let you use your mailing lists until a proper fix is implemented:
* While composing an email open the address book and select the list you are trying to send to, highlight all the names in the list and drag them to the To: box. This uses your existing data without modifying it.
* Replacing the blanks " " between the words in such lists' descriptions with an underscore "_". This requires modifying your mailing list(s) description(s).
* Downgrade to a previous version and disable automatic updates (Windows)

Add Users from people picker field to sharepoint group

Hi,
I have created infopath form and added people picker control and then created data connection to add users to sharepoint group.
Used UserGroup webservice and "AddUserToGroup" operation. If I select single user in people picker and click submit button, web service data connection adding user to sharepoint group without any issue but it's not working for multiple users.If
I select multiple users in people picker, web service adding only first user to sharepoint groups. In our company we do not prefer custom coding.
Can anybody help me out to resolve this issue?
Any help or suggestions would be appreciated.
Thank you,
AA.

You ll be able to achieve this by placing people picker in repeating table control in the form, below url may help you.

SharePoint 2013 July 2014 CU - People Picker fields empty in Edit forms

After applying the July 2014 CU for SharePoint server, I discovered that Person or Group (People Picker) fields are not populated with server values in list item Edit forms. However, the field values can be viewed in list views
and in Display forms. I examined the client side code and determined that field data is not being returned from the server for Edit forms.
In a test environment, I uninstalled SharePoint 2013, reinstalled SP 2013 with SP1 and the issue went away. I then applied the May 2014, June 2014, and July 2014 CUs. The issue did not exist after applying the May and June CUs. It
did exist after applying the July 2014 CU.

There is a workaround for this issue. It's a little convoluted, but hey, it's SharePoint. First, you must have a list that has at least one entry in it.
To begin with, you must first
have a list with at least one item in the list.
Next you edit the item with a role that has at least Design privilege, but don't save your changes.
Instead you Edit the page so you can then edit that web part. You can edit the page by clicking on the cog icon and selecting Edit Page
Edit the web part itself
Under “Miscellaneous” section on the just exposed web part window, select "Server Render (Server Render)" in the drop down labeled “CSR Render Mode
Click on “Apply” button within the web part
Save
I was told also the Sept CU would fix the issue but it is under review and to wait until the first of October. Incidentally we found that if you put the entire list into Quick Edit mode, the issue does
not appear.
I hope this helps someone.

Is there a way to exclude temporary people picker fields from a query when receiving the "List View Lookup Threshold" error.

Hi All,
My users require the ability to select a sharepoint group from a drop down list and then be able to select a user from a people picker based on the drop down selection.    The best solution I was able to up with, was create a people picker
for each drop down selection and set the Sharepoint group field to the selected group.  All people picker filed are hidden except the one that matches the drop down selection. When creating an entry from the sharepoint list this method
works perfectly.
However, when I add the list onto a site page using an "Listview webpart", then add an infopath web part and then finally connect the two parts, I get a "List View Lookup Threshold" error when selecting an entry from the list. I
understand from the error and reading that this error is related to the number of People pickers in the list.   Is there a way to exclude temporary people picker fields from a site page query, as they are only temporary fields to allow the users
to select a person and then assign the name to another field.
Dwayne

Hi Dwayne,
In SharePoint 2013, we could manually create a list for all users. Here are the reference:
Go to Site Settings > People and Groups > SiteMembers
Modify url
http://sitename/_layouts/15/people.aspx?MembershipGroupId=8 to
http://sp/sites/tutu/_layouts/15/people.aspx?MembershipGroupId=0 , now you will see All people in this site.
Change the view to List view, and copy the listview id in the url
http://sitename/_layouts/15/people.aspx?MembershipGroupId=0&View={viewID}
Go to Settings > List settings, copy the list id in the url
http://sitename/_layouts/15/listedit.aspx?List=listeid&Source=....
Now type the address in IE:
http://sitename/_vti_bin/owssvr.dll?CS=109&Using=_layouts/query.iqy&List=[LISTID]&View=[VIEWID]&CacheControl , such as
http://sp/sites/tutu/_vti_bin/owssvr.dll?CS=109&Using=_layouts/query.iqy&List=f3958d27-9c2f-4f8d-b221-89466e816667&View=696BFDC5-0C6E-4E27-818F-0E6292A18407&CacheControl=1
Save the owssvr.jqy from SharePoint site
Now you could see the file in your desktop with all users, save it as allusers in Excel.
Then import it to your SharePoint site, add an app > find an app > import spreadsheet

Apex and web services

Hello everyone,
I've started looking into SOAP and web services, and have used Tyler Muth's tutorial to email and FTP BI publisher reports using APEX.
I was wondering if it is possible to create an on-screen report (i.e. an interactive report) using a web service?
I've managed to return values to form fields using web services...I was always under the impression, from before I looked at web services, that creating an on-screen report using data from a web service was one of the main things you could do....
Please could someone let me know if this is possible, and roughly how you'd go about doing it?
Thank you in advance.
Robin

Hi Robin,
I think I have implemented the same thing which you are trying to do
The followinf is the response of a web service from BI Publisher. You can check the response using the statement
select clob001 from wwv_flow_collections where where collection_name = <name_of_the_collection_u_specified_while_sending_the web_service_request>

EAI AND WEB SERVICES

Hi,
What is the difference between web services and EAI ?
Thank you.

Hi,
Salient Differences between Traditional EAI Solutions and Web Services
A few essential differences between traditional EAI solutions and Web Services are, as follows:
Simple: There is no doubt that Web Services are much simpler to design, develop, maintain, and use as compared to a typical EAI solution which may involve distributed technology such as DCOM and CORBA. Once the framework of developing and using Web Services is ready, it will be relatively easy to automate new business processes spanning across multiple applications.
Open Standards: Unlike proprietary EAI solutions, Web Services are based on open standards such as UDDI, SOAP, HTTP and this is probably the single most important factor that would lead to the wide adoption of Web Services. The fact that they are built on existing and ubiquitous protocols eliminates the need for companies to invest in supporting new network protocols.
Flexible: Since EAI solutions may require point-to-point integration, changes made at one end have to be propagated to the other end, making them very rigid and time consuming in nature. Web Services based integration is quite flexible, as it is built on loose coupling between the application publishing the services and the application using those services.
Cheap: EAI solutions, such as message brokers, are very expensive to implement. Web Services, in the future, may accomplish many of the same goals - cheaper and faster.
Scope: EAI solutions, such as message brokers, integrate applications treating them as single entities, whereas Web Services allow companies to break down big applications into small independent logical units and build wrappers around them. For example, a company can write wrappers for different business components of an ERP application such as order management - purchase order acceptance, status of order, order confirmation, accounts receivable, and accounts payable.
Efficient: As mentioned in the previous point, Web Services allow applications to be broken down into smaller logical components, which makes the integration of applications easier as it is done on a granular basis. This makes Web Services solutions for EAI much more efficient than traditional EAI solutions.
Dynamic: Web Services provide a dynamic approach to integration by offering dynamic interfaces, whereas traditional EAI solutions are pretty much static in nature.

"People Picker" field not letting update SP linked table in Access

Hello all,
I have linked a SharePoint list to an Access database in order to manipulate some data. This list contains several fields, including a people picker in which its data come from SharePoint.
Once in my Access DB, I need to update some fields of this list, however when I try to change some values from a record that has the people picker populated I get the following error message: "you cannot reference rows created
when you are disconnected from the server because this violates the lookup settings defined for this table". I only get this when I have values on people picker, I can proceed without any problem when I have it set as blank.
So, do you have any idea on how to accomplish an update operation while having a people picker field populated?
Thank you in advance.

Hi Pedro,
I recommend to check if the user populated in the RequestBy exits in User Information List in SharePoint site and the choices listed in Access for status field are existed in SharePoint Status column.
Please refer to this thread for more details:

XML and Web Service Data Source Missing in Crystal Reports for VS

I would like to use a Web Service as the data source for a Crystal Report that will be running outside of my Visual Studio application. So setting the data source to the web service in code is not possible. My understanding is Crystal Reports has a connection (in the Database Expert under New Connection) named XML and Web Service. Here you can select web service and enter the WSDL URL for the web service. However it does not appear in the list for Crystal Reports for Visual Studio. Does this connection type come with the Visual Studio version of Crystal Reports and if not is their a way to obtain it?
Thank you for your assistance.

None of the bundled versions of CR have the driver. Reason is that the driver responsible for these connections requires the Java framework and I suspect MS would not be too pleased if we installed the Java framework. The stand alone versions, since they are not part of any bundle can and do install the Java framework and the driver. Note that even the latest release of CR - CRVS2010 does not have the driver as it essentially becomes a bundle or a VS2010 plug-in.
So, the short of it is; you have to obtain a stand-alone version of CR. I'd recommend CR 2008 (12.x) as CRXI R2 will run out of support in June of this year.

Can't run wiki and web services at the same time?

I'm a newbie with Lion Server, but I've been running several web sites successfully for about 6 months. I'm up to Server 10.7.4.
I've been trying ever since the first installation of Server to get the wiki service running. I had absolutely no luck until I turned OFF the web service (always got the "URL does not exist" error when I tried to create a group wiki from inside the Server app). With the web service off, it all starts up fine and I created my first wiki (woohoo). Turning web service back on kills access to the wiki. I don't find reference to this in any of the dicussions, and especially not in Apple's documentation.
Are the Wiki and Web services mutually exclusive? Or is there a way around this?
I'm using Dyndns to provide me with sub-domains to use, and I've dedicated one of them to the wiki service. Traffic comes in on port 8080, where my web sites are on port 80.
Thanks for any pointers...

LR supports tethering using a Canon DLL and EOS Utility probably also supports tethering or at least uses something from a similar Canon DLL. You probably cannot have two different versions of that DLL loaded at the same time, so it makes sense there are problems.

Message Monitoring and Web services Sequences .. SOAMANAGER

When can I use Mesage Monitoring and Sequence Monitoring .
We are making a proof a concept and we are the following.
1. A program which executes a proxy and with this proxy we are consuming a web services.
2. The proxy and web services were implemented in the same Abap Machine .
3. We execute the test and everything works very well and we consume the webservice and the program displays the expected result.
Now want to know How can we use the Message Monitoring and the Sequence Monitoring . Is this posible ? Do we have to make any previous configuration?
We don´t have any XI installation and for that we wonder if we can monitorize the webservices sequences ?
Any idea about if we can realize such king of actions ..
Many Thanks

Hi
I assumes u have dual stack.
You can do the sequence monitoring with or without PI. But without PI you would achieve that thing on the local machine.
You have to do those things at Java End using SAP NWA.

SSL certificates and Web Services Usage inside Oracle Database Questions!

We have implemented a specific business logic using PL/SQL for our client, so we open a file and process each line of this, doing something in the Database and also call a Web Services (Service1) using UTL_HTTP package. Service1 runs in a Windows 2008 Server in the DMZ as Database server.
Service1 is already working, and we can call the service from PL/SQL without troubles.
However, according with security client's policies they requires all Web services be consumed via https including Service1, so we must to follow the procedure established for Oracle in order to enable the calling of service1 via https from the Database.
Our client's DBA and IT Team are concerned about two subjects before to continue to follow the certificate installation:
     - SSL Certificates:
1- Can installed certificates in the Database put in risk the stability of the database?
          2- Can installed certificates in the Database generate performance issues?
          3- Can installed certificates reloading the Databases?
          2- Can installed certificates in the Database generate security issues?
     - Web services:
1- Can web services calling from the Database put in risk the stability of the database?
2- Can web services calling from the Database generate performance issues?
3- Can web services calling from the Database generate security issues in the DMZ?
Could you please give us any clues, about the possible negative impact related with the SSL certificates and Web Services Usage inside Oracle Database, if it’s the case this impact exists?.
Those are the links describing the procedure mentioned above.

DB: Oracle 9i.
Average number of lines in file: 300
Periodicity: Twice at day.

Thiago:
You are correct in that there should be no problem interacting with a Web service that has an HTTPS endpoint as long as you create a wallet and specify it when you make your UTL_HTTP calls, like the PayPal example.
I am not aware of a PL/SQL utility to create a XMLDsig Standard message, but if you find some Java source out there that does it, you may be able to follow a technique I used for a similar use case:

Custom Portal Services and Web services

Can you please tell me what exactly are "custom portal services" and "web services" with a business like/ real life example?
How do you go about developing deploying and utilizing these services in Portal?
Thanks.

Hi navin,
Thanks for the par file.
Duly awarded points.
I need your help again.
I wish to use the method
public String getWelcomeString(String name)
in my own portal application to test usage of portal services.
So I uploaded your par file on my server.
Then I added the api and core jar files which came along with your par in my project as external jar files.
I imported com.wickes.WickesService.*;
Next, to use the service I coded:
IPortalRuntimeResources rs =
PortalRuntime.getRuntimeResources();
IWickesService ws = (IWickesService) rs.getService(IWickesService.KEY);
But now I am stuck and I dont know how to proceed.
Please help.
