Plugin not initializing

[issmirnov]

Hey there,

I installed this plugin on the latest RC of Dokuwiki (Hogfather).

I created a sample page:

<flow>
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;    
click A "SOMEPAGE"
</flow>

The page does not render.

Console logs show:

mermaid-init.js:1 Uncaught ReferenceError: mermaidAPI is not defined
    at mermaid-init.js:1

I can confirm that /plugins/flowcharts/mermaid.min.js exists and is loading:

Can you help debug? Happy to post more logs, etc.

I edited the mermaid-init.js to call mermaid.mermaidAPI.initialize. This solves the JS issue seen in console. However, after checking server side logs:

Seems there's an issue with Doku_Parser_Mode_internallink caused by https://github.com/jakob1111/dokuwiki-plugin-flowcharts/blob/master/syntax.php#L72?

Same here, using version 0.1 doesn't work either in current dokuwiki version.

@issmirnov, I purpose an issue close as my rendering problem stopped with installing latest commit on my Hogfather dokuwiki.

Confirmed, just tested and this works. Thank you for flagging.
