Hi Community!

I want to share with you my impressions of Global Summit 2018.

It was my first time in the USA and my first Global Summit. And I can say that it was really amazing trip and a great experience!

I have been building Business Processes in Ensemble for a few months and in a process i'd use a combination of data from the request that started the process and context variables that where filled by earlier calls in the process as input for a data transformation. I do not know how to achieve that.

This code snippet provides a ZEN page that downloads a stream from its database directly:

/// We assume that you have stored your data within this schema:
/// MyApp.Model.Storage: Filename,FileSize,Content,ContentType
Class zen.downloadStream Extends (%ZEN.Component.page,%CSP.StreamServer)
{
 
    /// Wrapper to get the id of the download, we assume that the id is passed to this zen page
    /// as a URI parameter, i.e.: MyApp.Downloads.cls?OID=1234
    ClassMethod GetId()
    {
        Quit $Get(%request.Data("OID",1))
    }
     
    /// Set the appropriate header for the file.
    ClassMethod OnPreHTTP() As %Boolean
    {
        Set tId = ..GetId()
     
        If ##Class(MyApp.Model.Storage).%ExistsId(tId) {
            Set tStream = ##Class(MyApp.Model.Storage).%OpenId(tId)
            // You could "guess" the content type by its file extension
            // or you can store it (before) in the database separately (like in this example).
            // Set Extension = $Piece(tStream.Filename,".",$Length(tStream.Filename,"."))
            // Set ContentType = ..FileClassify(Extension)
     
            Set %response.ContentType = tStream.ContentType
            Do %response.SetHeader("content-disposition","attachment; filename="_tStream.Filename)
            Do %response.SetHeader("Content-Length",tStream.FileSize)
        }
        Else {
            Set %response.Status="404 File Not Found"
            Quit 0
        }
        Quit $$$OK
    }
     
    ClassMethod OnPage() As %Status
    {
        Set Download = ##Class(MyApp.Model.Storage).%OpenId(..GetId())
        Do Download.Content.OutputToDevice()
        Quit $$$OK
    }
 
}

Hello!

Is it possible to use Cache Studio on a Linux operating system? Maybe there are similar tools for Linux?

I have created some roles, and would like to know if there is a way to export the Roles and save them off to a file? I want to create a backup file of these roles for DR purpose, and in case I ever get hit by the preverbal bus.

Thanks

Using our cool new debugging extension for Visual Studio Code I'm trying to debug a CreateProjection method of a class, but when I compile it the work apparently gets done in one of the worker jobs, so my breakpoint never triggers.

Is there a compiler flag or qualifier to force the compilation to be done in-process rather than getting handed off to a worker job?

Hello,

I have a question about creating properties with curl.

I already did create properties in Java with the following command.

<DO db.%CreateProperty("TotalSteps","%Integer","$.TotalSteps")>

It created the property TotalSteps with the type %Integer and the data path $.TotalSteps (since the header of my data source is also TotalSteps).

Now I would like to create the same property in curl with the following command

Hello,

Atelier 1.2 as well 1.3 throws java.lang.NullPointerException when opening a class file.

Never mind how to open the class file, 1) witin project explorer 2) atelier explorer 3) open resources 4) switcing between tabs (open files) etc..., I get these errors every time.

Never seen this problem in Atelier 1.1.

Do I miss something within the Eclipse environment?

Does anyone has the same problem?

Best Regards,

Roger de Coninck.
