Hi,

I have spent today updating to Kentico 6 and I have run into an issue with a custom data source I created for 5.5r2. For some reason this web part no longer works and causes my app pool to die. I have tried debugging using remote debug to our dev server but it won't load the source files. It looks like my code is causing a stack overflow. Anyway, here is the source.

using System;
using CMS.CMSHelper;
using CMS.Community;
using CMS.Controls;
using CMS.DataEngine;
using CMS.SettingsProvider;
using CMS.SiteProvider;

public partial class CMSWebParts_DataSources_PeopleYouMayKnowDataSource : CMSBaseDataSource
{
    #region "Variables"

    private string mWhereCondition = String.Empty;
    private string mOrderBy = String.Empty;

    #endregion


    #region "Properties"

    /// <summary>
    /// Gets or sets the where condition
    /// </summary>
    public string WhereCondition
    {
        get
        {
            return mWhereCondition;
        }
        set
        {
            mWhereCondition = value;
        }
    }


    /// <summary>
    /// Gets the data source
    /// </summary>
    public override object DataSource
    {
        get
        {
            return base.GetDataSource();
        }
    }

    /// <summary>
    /// Gets or sets the order by clause
    /// </summary>
    public string OrderBy
    {
        get
        {
            return mOrderBy;
        }
        set
        {
            mOrderBy = value;
        }
    }

    #endregion


    #region "Methods"

    /// <summary>
    /// Handle filter change event
    /// </summary>
    protected override void OnInit(EventArgs e)
    {
        if (SourceFilterControl != null)
        {
            SourceFilterControl.OnFilterChanged += new ActionEventHandler(DataFilter_OnFilterChanged);
        }

        base.OnInit(e);
    }


    /// <summary>
    /// OnFilterChange handler
    /// </summary>
    void DataFilter_OnFilterChanged()
    {
        // Clear old data
        InvalidateLoadedData();
        // Raise change event
        this.RaiseOnFilterChanged();
    }

    protected override object GetDataSourceFromDB()
    {
        if (base.DataSource != null)
        {
            return base.DataSource;
        }

        GeneralConnection cn = ConnectionHelper.GetConnection();

        if (!string.IsNullOrEmpty(WhereCondition))
        {
            WhereCondition = " and " + WhereCondition;
        }

        var qdp = new QueryDataParameters();
        qdp.Add("@UserID", CMSContext.CurrentUser.UserID);

        base.DataSource = cn.ExecuteQuery("cms.user.peopleyoumayknow", qdp, WhereCondition, OrderBy, TopN, SelectedColumns);
        cn.Close();

        return base.DataSource;
    }

    #endregion
}
