Hi everone!.
I am using Mindfusion diagramming. I want to make an Organogram in react. for that I installed npm mindfusion-common
and npm-diagram-library-react. but when i execute the code, it returns this error:
"TypeError: Cannot read property 'TreeLayout' of undefined"
Can anyone help me with this?
Thanks, Zain

Hi!

You can find TreeLayout used in the Samples\React\src\Inheritance.js example. Doesn't it work for you when you do npm install & npm start (in parent folder)?

Hi Thanks for the time!
Actually I copied to code of Organogram from Mindfusion website. It worked fine in the simple HTML file. But when I moved to React it gave errors, then I install mindfusion library and imported
'mindfusion-common' which solved many errors. Now it's giving an error on the line :
"var TreeLayout = MindFusion.Graphs.TreeLayout;"
I don't know what to do now. I installed react-library too but in vain. Kindly help me

Update:
So I added two more imports which nearly solved the error :

Now it is saying "Can not read property 'id' of null" in the file
"MindFusion.Common" and in the following lines:

var cg = new cb(cf, cc);
[b('0x4a')] = cf;
this[b('0x9')](cg);
this[b('0x4b')][b('0x4c')](cf['id'], cg);
cg[b('0x31')]();
return cg;

It shows the organogram for a second and disappears afterwards.

Have you placed the diagram canvas inside a div? The control expects a parent div serving as scroll-view, tooltip container and other DOM access operations. Otherwise please attach your test html and js code and our developer will investigate.

By Organigram do you mean this example of ours? We'll try to adapt it to React later today...

We've added that code as a new tab in the React example -

Hi thanks for the help. I solved it somehow, but my request would be to upload as much videos as possible on your YouTube channel showing how to use MindFusion products Smiley
