Hi,

I was wondering if anyone had experienced the following issue before and could help?

I am using Merchello Core 2.7.1

I have setup a document type which has a Product Collection Picker on it, this document type is used to display a listing of the products in a collection or an "All Products" listing.

For the pages that use this document type and have a collection selected in the backoffice, the listings load correctly with no errors in the logs. However, for the "All Products" listing I have selected "All items" in the backoffice. When this page is loaded I get an error in the log file stating unrecognised Guid format.

Merchello.Web.PropertyConverters.ProductCollectionValueConverter - Failed to Convert ProductCollection property System.FormatException: Unrecognized Guid format. at System.Guid.GuidResult.SetFailure(ParseFailureKind failure, String failureMessageID, Object failureMessageFormatArgument, String failureArgumentName, Exception innerException) at System.Guid.TryParseGuid(String g, GuidStyles flags, GuidResult& result) at System.Guid..ctor(String g) at Merchello.Web.PropertyConverters.ProductCollectionValueConverter.ConvertDataToSource(PublishedPropertyType propertyType, Object source, Boolean preview)

I have looked into the Merchello v2.7.1 code and have ran Merchello locally to test. It appears that here in the ConvertDataToSource function:

        if (source == null)
            return null;

        try
        {
            var key = new Guid(source.ToString());
            var collection = MerchelloContext.Current.Services.EntityCollectionService.GetByKey(key);
            return collection != null ? new ProductCollection(collection) : null;
        }
        catch (Exception ex)
        {
            MultiLogHelper.Error<ProductCollectionValueConverter>("Failed to Convert ProductCollection property", ex);
            return null;
        }

The source object is an empty string when selecting "All items". Is this correct?

Thanks, James
