Issue with dynamically adding then removing output_1, output_2 about drawflow HOT 23 CLOSED

for example when I remove node output_3 from condition_desc, it works, but when trying to remove 2nd it gives issue,

For adding new output I'm using this:

from drawflow.

from drawflow.

In drawflow outputs and inputs as sequential number.

Example:
If you have 3 outputs.
And eliminate number 2.
Outputs 1 and 2 will remain available.

You are using the functions: removeNodeOutput(id, output_class) and addNodeOutput(id)?

Use

editor.addNodeOutput(idOfNode);

from drawflow.

if I use like this, how I can add lables?

from drawflow.

is there any function that I can check if output exists or not?

from drawflow.

I don't know how you are adding the labels.

But once the connection is added you can always access the node information or add the label to the created connection.

You can get the node information with the function:

const dataNode = editor.getNodeFromId(idOfNode);

Here you can see the outputs and inputs of the nodes.

from drawflow.

There is no function.
But you can use what was shown in the comment above to see if the output exists.

tthis will remove "removeNodeOutput(id, output_class)" from child node inputs?

from drawflow.

Yes

In drawflow outputs and inputs are sequential number.

There can be no jump in them.

@jerosoler I'm using .removeNodeOutput() function wrongly?

from drawflow.

as I understand the problem is when node has any outputs + connection removeNodeOutput() gives error.

from drawflow.

When I try to remove first output which has a connection I see this error

when removing output_2 or output_3 it gives this error

and it works when I remove connection and try remove output again

Please create a codepen to reproduce this problem.

I'm not able to copy json from my working place, I can send screenshots

I found the problem, closing the ticket, thanks.
