My problem is that the RichTextBox from the aspx is generating an error:

undefined: Cannot read properties of undefined (reading 'getValue')

Here is my code:

   <pxa:PXRichTextEdit ID="CstPXTextEdit5" runat="server" 
            Style="z-index: 113; border-width: 0px;"
            AllowAttached="true" AllowSearch="true" AllowLoadTemplate="false" AllowSourceMode="true"
            DataField="Answer" Width="800" Height="900">
            <ContentStyle BorderStyle="None" ></ContentStyle>
            <AutoSize Enabled="True" ></AutoSize>
        </pxa:PXRichTextEdit>

Hey! Thanks for sharing this. Could you walk us through what you're trying to build? What is the API you're calling, what triggers the call, and where in Acumatica (for eg: which screen?) are you trying to show the response to the user?

The API is a custom DLL - the user triggers the call with a button click on a custom screen… and the call works.  I’m having trouble getting a RichText box what doesn’t pop up “undefined: Cannot read properties of undefined (reading 'getValue')” - I’ve seen this on the forums (2 years ago), but the best answer includes aspx code for an additional field…  

 

 <px:PXRichTextEdit ID="edBody" runat="server" DataField="UsrBody" Style="border-width: 0px; border-top-width: 1px; width: 100%;"
         AllowAttached="true" AllowSearch="true" AllowLoadTemplate="false" AllowSourceMode="true">
         <AutoSize Enabled="True" MinHeight="216" />
         <LoadTemplate TypeName="PX.SM.SMNotificationMaint" DataMember="Notifications" ViewName="NotificationTemplate" ValueField="notificationID" TextField="Name" DataSourceID="ds" Size="M" />
     </px:PXRichTextEdit>

Does this not reference two fields?
