    I'm getting this error on RenderForms method in Umbraco Forms. Did you found anything useful or maybe solved this problem in your solution @Alex?

    Hi Marcin,

    We didn't find a solution for RenderController. We decided not to use it in an async way and honestly said, do not use them at all.

    UmbracoApiController works fine with async.

    Cheers, Alex

    Do you want to use RenderForm in async wrapped method?

    Problem occurs when Umbraco Form is inside the Grid and it's wrapped using LeBlender. I'm assuming that it's called using async way and cause the problem. It's weird because it's working on our staging server and not working on all devs instances.

    Maybe this key can help:

     <setting key="ExecuteWorkflowAsync" value="False" />
    

    Its from \App_Plugins\UmbracoForms\UmbracoForms.config

    Thanks

    Thanks Alex. I think that this is related to workflows, not rendering (as described in comments) and my form is not rendered yet to even think about workflows :)

    Going to test on fresh installation probably or dig more into LeBlender / Forms sourcecode.

    {"Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'."} System.Web.HttpException

    Error loading Partial View script (file: ~/Views/MacroPartials/InsertUmbracoFormWithTheme.cshtml)

    I am currently having the same issue using Umbraco 7.7.3 and Umbraco Forms 6.0.3 the past 2 days. This is the error I'm getting: Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

    In my Visual Studio it shows a little more detail. When the InsertUmbracoFormWithTheme macro executes and error is in the RenderAction. Based off of the error, it is trying to use an old connection to a previous umbraco database I had created the forms on, instead of the new umbraco database(which has a different name than the previous) the forms are on now. Any help with this would be much appreciated as I do not want to recreate the forms on the new database.

    I was having this same error. For me, it was because we had old content that still picked the Insert Form (Legacy) macro. To resolve the problem, I configured the Insert Form (Legacy) macro to not try to render in RTEs or grids.

    I experienced this problem when I made async calls in my action result in my surface controller, and updating all async calls to sync fixed my problem - not happy with this solution.

    Umbraco version 7.15.4 assembly: 1.0.7381.11453
