I have a Confluence page with a draw.io diagram attached. I can see the diagram XML and a PNG in the attachments list for the page but the diagram is not shown on the page.
If I insert a new draw.io macro, I don't get the popup shown at https://support.draw.io/display/DFCS/Adding+a+draw.io+Diagram+to+a+Confluence+Page that would allow me to search for a diagram or select a recent diagram.
How do I insert a draw.io macro that references this existing diagram?
To recover the diagram save the diagram XML locally, then insert a new draw.io diagram into that Confluence page. When the diagram editor is open drag and drop that saved XML into the editor and the diagram will load. Then save the new diagram to the page.
The current mechanism does seem to occassionally save the diagram to a child page, instead of the current parent. Atlassian are releasing a fix to this on Monday, https://ecosystem.atlassian.net/browse/ACJS-107, that should deal with that.
There's an additional issue affecting saving attachments to draft pages that Atlassian need to resolve https://ecosystem.atlassian.net/browse/CE-288. Votes on that would help raise the priority of the issue.
The proposed solution doesn't really solve the problem. As Mark pointed out the behaviour described in the offical docs (https://support.draw.io/display/DFCS/Adding+a+draw.io+Diagram+to+a+Confluence+Page) doesn't occur in confluence when trying to add an existing diagram to a page. You should consider editing the docs, with some troubleshooting, or fix the bug in drawio plugin.
Secondly the propsed solution doesn't provide the desired workflow. If I want to use the same graph on multiple pages, I wan't to have 1 graph loaded. If I have 6 images with the same grpah I would need to copy the XML (as proposed) 6 times, and have 6 identical files saved in the cloud.
Main problem imho is that the offical docs are describing a feature withc either doesn't exist, or it has bugs. You should fix this either way.
I don't agree it's a bug, but I can see it would be useful (not sure the plugin is "totally" useless in its current state either :) ). draw.io is a static plugin in cloud, I don't think a search is possible in the splash. What about if we allowed you to paste a URL of an attachment to implement this?
Draw.io isn't useless w/o this feature - but it would be extremely useful if I could embed the same Diagram on multiple confluence pages - maintaining one source of truth for whatever the purpose the diagram is intended for.
If a search isn't possible (ideal case), then pasting a URL would be very helpful and provides the single source of truth for a diagram used on many Confluence pages.
