Are sections inside Sitecore Webforms for Marketers restricted to 10?

Question

I am using Sitecore.NET 8.1 (rev. 160519) + Web Forms for Marketers 8.1.rev. 160523. I created a sample form with 12 sections and 1 single-line text field in each section (total: 12 text-box fields).

When I am debugging the list of field/value in a custom Save Action in "AdaptedResultList", the field value of second Section's field + field value of eleventh section's field is getting replaced with value of 12th section's field.

If I keep sections upto only 10 then I am perfectly getting the value .

Is Sitecore WFFM restricted up to 10 sections?

This is a known defect. You should request hotfix 434449 from Sitecore Support.

Or just follow these steps:

1. Download the hotfix DLL:
   a) For Sitecore 8.0: Sitecore.Support.434449.dll
   b) For Sitecore 8.1 Update 2 or later: Sitecore.Support.434449.81.dll
2. Put the DLL to your website's bin folder.

3. Create a .config patch under App_Config/Include/zzz.
   a) If you have Sitecore 8.0, put the following content in the patch file:

   <configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:x="http://www.sitecore.net/xmlconfig/">
     <sitecore>
       <pipelines>
         <initialize>
           <processor
             type="Sitecore.Support.Forms.Mvc.Pipelines.AddCustomMetadataProvider, Sitecore.Support.434449"
             patch:instead="*[@type='Sitecore.Forms.Mvc.Pipelines.AddCustomMetadataProvider, Sitecore.Forms.Mvc']" />
         </initialize>
     </sitecore>
   </configuration>
   

   b) For Sitecore 8.1 Update 2 or later:

   <configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:x="http://www.sitecore.net/xmlconfig/">
     <sitecore>
       <pipelines>
         <initialize>
           <processor
             type="Sitecore.Support.Forms.Mvc.Pipelines.Initialize.AddCustomMetadataProvider, Sitecore.Support.434449.81"
             patch:instead="*[@type='Sitecore.Forms.Mvc.Pipelines.Initialize.AddCustomMetadataProvider, Sitecore.Forms.Mvc']">
             <param name="perRequestStorage" ref="/sitecore/wffm/data/perRequestStorage" />
             <param name="corePipeline" ref="/sitecore/wffm/corePipelineWrapper" />
           </processor>
         </initialize>
     </sitecore>
   </configuration>
