Visual Overview – [GUID] placeholder usage on SRM

Hello everyone,

I created a Visio file for a resource in my DMA and initialized a variable using this:

When I display this variable value in another shape, it correctly displays my Resource GUID.

But when I try to re-use this variable content in another placeholder, it fails. As a workaround, if I type the GUID directly in the shape, it works fine.

Here's my Visio file:

Here's the result:

I was expecting both approaches to give me the same result. Does anyone knows why the variable approach doesn't work?

(I'm using DataMiner 10.1.2.0-9866)

It seems like several concepts got a bit mixed up here:

  1. The [Guid] placeholder, which is currently only supported in the InitVar shape data, generates a new unique guid. This guid is by no means related to anything on your Visual Overview and is totally random. It is meant as a random seed for your local session.
  2. The set of the session variable during the InitVar will only occur when that session variable has no value in it's current context. In your example, I believe the ThisGuid session variable already has been set to the guid of the resource. Since this is a global session variable, this value is never cleared and using it in an InitVar will no longer do anything. Instead, you can try using a CardVariable or PageVariable which both have a new context for a new card.

Thanks for the clarification Sebastiaan.
So the [Guid] placeholder is something else, not related to the Resource GUID.
