Using the React sample from yfiles-for-html-demos/toolkin/react and adding react-router-dom built it capabilities to the sample application the Graph is only being rendered for the first time.
The behaviour can be seen here https://github.com/hammerhg/yfiles-react-demo-test.

To Reproduce
Steps to reproduce the behavior:

1. Clone https://github.com/hammerhg/yfiles-react-demo-test
2. Fix the location of the yfiles-23.0.4-dev.tgz and licence.json
3. npm install
4. npm start
5. In the browser window make sure that the graph nodes and edges are visible.
6. Click on the Other page link on he top left.
7. Click on the Graph link on he top left.
8. Observe that the nodes and edges are not visible.
9. Refresh the page and observes the nodes and edges are visible.

Expected behavior
When navigating away and back to the graph page using react-router-dom built it capabilities the graph nodes and edges should be rerendered.

Hello.. i downloaded ur source code want to know can i add my own shapes and electric circuit shapes.. ?? and save them or make a user to login thank you

https://github.com/yWorks/yfiles-for-html-demos/blob/master/demos/complete/frauddetection/InteractiveLayout.js#L71

this.copiedLayoutGraph = new yfiles.layout.CopiedLayoutGraph(adapter)

CopiedLayoutGraph constructor requires as 1st param a LayoutGraph type and LayoutGraphAdapter is not one.

In order to fix it use createCopiedLayoutGraph method defined in scope of LayoutGraphAdapter class as below:

this.copiedLayoutGraph = adapter.createCopiedLayoutGraph()

Hello! I was wondering if it is possible to add children to a node and refresh the orgchart with new data dynamically?

Describe the bug
When the demo at https://github.com/yWorks/yfiles-for-html-demos/tree/master/demos/toolkit/react is run the demo allows to add Nodes to the graph, but whenever you try to reset the graph using the reset button or remove any node one gets following error message:

Unhandled Rejection (ArgumentError): Affected parameter edge: Edge not in this graph!

ReactGraphComponent.updateGraph
src/components/ReactGraphComponent.jsx:196

193 | // update the graph based on the given graph data
194 | this.graphBuilder.setData(this.nodesSource, this.props.graphData.nodesSource)
195 | this.graphBuilder.setData(this.edgesSource, this.props.graphData.edgesSource)
->196 | this.graphBuilder.updateGraph()
197 | ^
198 | // apply a layout to re-arrange the new elements
199 | const layoutExecutor = new LayoutExecutor(this.graphComponent, new HierarchicLayout())

To Reproduce
Steps to reproduce the behavior:

1. Run the project with > npm start wait for the Demo to start in the browser
2. Click on 'Remove Node' button
3. See the error

OR

1. Run the project with > npm start wait for the Demo to start in the browser
2. Click on 'Add Node' button
3. Click on 'Reset' button (left top)
4. See the error

Expected behavior
Remove the node and refresh the graph.

Additional context
Further debugging shows, that for some reason
this.graphBuilder.setData(this.nodesSource, this.props.graphData.nodesSource) this.graphBuilder.setData(this.edgesSource, this.props.graphData.edgesSource)

setData method internally compares the nodes and edges given in the props and cannot identify the node to be removed.

Hello,

I'm Fabio, and I'm evaluating the yFiles layout library.
Experimenting with the BPMN layout code from the demo, I found that (not sure if it's a bug or something I didn't understand):

the mapper maps edges, the data provider is using that mapper for nodes.
Is it correct? What I am missing?

thanks,
Fabio Pignaton

In network monitoring demo,
location(x,y) of nodes, edges are given by hardcoding in network-sample.ts

Is there any way to auto-calculate for location(x,y)?

Currently I am considering to feed network(nodes,edges) from database, and wondering how to give x,y.

Thanks for your help.

P.S. FYI, I am a licensed user.

I was trying to enable undo and redo as shown in demo https://live.yworks.com/demos/tutorial-yfiles-basic-features/07-undo-clipboard-support/
I the graph is an instance of DefaultGraph everything works as expected, but if I use a grouped graph I get the following error in console:

constructor {message: "Affected parameter graph: Provided graph can't provide undo support", name: 'ArgumentError', cause: null, stack: 'ArgumentError: Affected parameter graph: Provided …les/react-dom/cjs/react-dom.development.js:90:45)'}
cause:null
