hey folks, I just tried to add a custom YesNo field to the products module through the interface and although the process seemed to complete without error, but now I receive the message below when trying to view the Products module. is there a bug in the way these values are parsed?

i looked at the xml config for the module and the value field seems pretty straightforward

<field mutuallyExclusive="True" renderChoiceAs="SingleCheckBox" hideTitle="True" dataFieldName="Taxable" value="False" type:value="System.Boolean, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" wrapperTag="Li" title="Taxable" example="Should taxes be applied to this product" fieldType="Telerik.Sitefinity.Web.UI.Fields.ChoiceField" type:fieldType="System.RuntimeType, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" cssClass="" hidden="False" fieldName="Taxable" type:this="Telerik.Sitefinity.Web.UI.Fields.Config.ChoiceFieldElement, Telerik.Sitefinity, Version=4.0.1210.0, Culture=neutral, PublicKeyToken=b28c218413bdf563">
<choicesConfig>
<clear />
<element text="Taxable" value="True" enabled="False" selected="False" />
</choicesConfig>

I commented out the field definitions in the .config file and then I could load the manager, view products, and edit custom fields. Setting it's predefined value to "" caused the same issue.

I repeated the process and then put "Yes" as the default value. This time I received Cannot access a disposed object. Object name: 'Database has been disposed.'.  A restart of the app solved that and appears to allow the fields to work as expected.

I do want to note that the Products module is still exhibiting the behavior I described in the post linked below. (i.e when I add a Custom field I will get itemContext.item is null or undefined, and return code 0 when trying to Edit/Insert. Turning off the app, Clearing cache and walking away for a while seems to fix this, but it's frustrating as heck for an end user, and unacceptable for a production site.

Hi Drew,

Thank you for the feedback. 
We agree that there is a lot to polish in this area. Fortunately with the Q1 release, we will bring a lot of improvements all over the place.
