    Hello,

    I have the following error when adding a CRM Lookup on a form :

    Multiple controls with the same ID 'radWindowManager_alerttemplate' were found. FindControl requires that controls have unique IDs.

    I tried changing the DeveloperName, but not works.

    Do you know what could be the issue ?

    Thank you,
    Julien

    It was a problem with the template and the ID of the PlaceHolder :

    ContentPlaceHolder ID="MainContentPlaceHolder"
