WFFM error on a form page

Question

When I'm opening one form of my build that runs with WFFM this is the error I get:

Could not find configuration node: wffm/modelFactory

anyone know what this error is all about? where is this configuration set? thanks

UPDATE: Sitecore 8.0 rev 160115

WFFM: 8.0 151127

Answer 1

Looking at the default config for that version of WFFMs that node is not in the config (the wffm node is there but I can't see the modelFactory).

As Gatogordo suggests this node exists in previous versions of WFFMs:

<wffm>
  <formProcessors>
    <processor type="Sitecore.Forms.Mvc.Processors.SitecoreFormProcessor, Sitecore.Forms.Mvc"/>
  </formProcessors>

  <modelFactory type="Sitecore.Forms.Mvc.Data.ModelFactory, Sitecore.Forms.Mvc" singleInstance="true">
    <param name="renderingContext" ref="wffm/renderingContext"/>
  </modelFactory>

  <renderingContext type="Sitecore.Forms.Mvc.Data.Wrappers.WrappedRenderingContext, Sitecore.Forms.Mvc" singleInstance="true"/>

  <formDataManager type="Sitecore.Forms.Mvc.Data.FormDataManager, Sitecore.Forms.Mvc" singleInstance="true">
    <param name="processorFactory" ref="wffm/formProcessorsFactory"/>
  </formDataManager>

  <formProcessorsFactory type="Sitecore.Forms.Mvc.Data.SitecoreProcessorFactory, Sitecore.Forms.Mvc" singleInstance="true"/>
</wffm>

So either your DLLs are old and expecting old config - or the installer is wrong and this config needs to be present in Sitecore.Forms.Mvc.config

I would redownload the installation package from the link above, unpack it and compare the DLL versions against your bin folder, also look for extra DLLs perhaps. If they all look correct, try adding that config node back in and see if it works.

Be worth logging this with Sitecore as well if the config on the installation package is incorrect.
