Should it be possible to use CustomMethodRecordCountParamName with the output parameter from a views custom stored procedure?
Looking in \Components\Views\ComponentViewDataAccess.cst it looks like the ability to use the custom stored procedures output parameters has been removed:
//Call Custom Procedure from Repository
//<%= returnType != "void" ? "result = " : "" %><%= newCollection %>dataProvider.<%= GetClassName(SourceView, ClassNameFormat.Provider) %>.<%=methodName%>(transactionManager, start, pageLength <%=TransformStoredProcedureInputsToDataAccess(true, command.InputParameters) + TransformStoredProcedureOutputsToDataAccess(true, command.AllOutputParameters)%>)<%= newCollectionEnd %>;
<%= returnType != "void" ? "result = " : "" %><%= newCollection %>dataProvider.<%= GetClassName(SourceView, ClassNameFormat.Provider) %>.<%=methodName%>(transactionManager, start, pageLength <%=TransformStoredProcedureInputsToDataAccess(true, command.InputParameters) %>)<%= newCollectionEnd %>;
