Synchronize SLAM

Mar 3, 2010 at 4:10 PM


First, great work guys, this is something we have been looking out for some time.

After installing SLAM and creating a simple relation to a sharepoint list, I got the following error:

System.NullReferenceException: Object reference not set to an instance of an object. at AWS.SLAM.Configuration.XmlSqlDataMapping.GetTypeFields(String id, String typeName) at AWS.SLAM.Events.ListItemUpdater.Update(SPListItem listItem)

Here's how my slam.config file looks like:

<DataMapping DataSchema="SLAM">
    <List Name="VerlofAanvraag" ActivationOrder="1">
        <Field Name="Gebruiker" SqlType="varchar(255)" SPType="Text" Required="false"></Field>

In my database I have a table called SLAM.VerlofAanvraag containing the following fields: ListItemId varchar(40) not null, ListID varchar(40) not null, ListRelativeId int not null, Gebruiker varchar(255) null. 

I added a few links to some screenshots.

Any help would be nice.

With kind regards,

Are you using v1.3?  I'm assuming if you activated it successfully/it created tables that your config validates without any issues and you have event handlers attached to your list.  This is happening when you just edit an item in your list?

Thx for your reply, I've figured it out.  I made a typo, the name of the list "VerlofAanvraag" should have been "Verlofaanvraag".

I didn't get any errors when I validated the slam.config.  The error occured when I synchronized for the first time. My version = 1.3.

With kind regards,
