I have created a custom submit based on the below module:


It went all hunky dory on my dev machine but when moved to our staging environment it started submitting twice and thus sending two emails. I added some logging to my custom code and it is definitely a submit of the same form as the SessionId, TemplateId etc. are all identical.

During my frantic googling I came across the below question on stack exchange which looks like the same problem but there wasn't an answer given.

Sitecore 9 Forms Custom Submit Model called twice

The bit I am missing is what happens between the form being submitted and it hitting the execute method on my submit action. Any pointers on where I can troubleshoot around that would be great.

I am stumped with the above so any help would be greatly appreciated. Please let me know if any more information is needed.



P.s This is my first time asking a question on StackExchange so please let me know if my question could have been clearer and/or more helpful.

  • is it enable Ajax Post check box? If is enabled can you disabled it and check again ? – Vlad Iobagiu Nov 19 '20 at 15:07
  • @VladIobagiu Thanks for reply. Just tried the above and when submitting I get an error. – Shaun121 Nov 19 '20 at 15:15
  • @VladIobagiu I will post the error above as it is too long for comments. Thanks for the advice I'll look at why my forms are erroring without Ajax – Shaun121 Nov 19 '20 at 15:17
  • @VladIobagiu just realised that adding the error above may muddy the water somewhat so here's the error on this question: sitecore.stackexchange.com/questions/23759/… – Shaun121 Nov 19 '20 at 15:20
  • when you submit do you see 2 formsbuilder in the network tab in Chrome/ Developer Tools , something like : formbuilder?fxb.FormItemId=5fd6197f-ffdb-4426-9298-07eaf4865b02&fxb.HtmlPrefix=fxb.24481816-6c0e-49fb-bf2b-2275e185ffb1 – Vlad Iobagiu Nov 19 '20 at 15:32

I had some problems with Sitecore forms submit when Ajax was enabled (not submit duplication though). The solution in was to edit: \Views\FormBuilder\Form.cshtml and add @Html.RenderFormStyles() above form definition and @Html.RenderFormScripts() below form definition like so:


    using (Html.BeginRenderRouteForm(Model, IsPost))
        @Html.Hidden(AttributeNames.FormItemId, Model.ItemId)
        <input type="hidden" data-sc-fxb-condition value='@Html.RenderConditions(Model)' />
