[REACT] Fixed effort + backwards mode and predecessor throws dependency error

[arnaus]

Hi,

I managed to reproduce a bug in the https://bryntum.com/products/gantt/examples/resourceutilization/

const gantt = new Gantt({
    project,
    dependencyIdField : 'sequenceNumber',
    resourceImagePath : '../_shared/images/transparent-users/',
    appendTo          : 'container',
    collapsible       : true,
    header            : false,
    minHeight         : 0,
    viewPreset        : 'weekAndDay',
    tickSize          : 40,
    columnLines       : true,
    startDate         : '2024-01-16',
    columns           : [
        { type : 'name', width : 280 },
        { type : 'SchedulingDirection', width : 280 },
        { type : 'schedulingmodecolumn', width : 280 },
        { type : 'predecessor', width : 280 },
        { type : 'resourceassignment', showAvatars : true, width : 170 }
    ]
});

Steps to repro:

1. Set task Report to managment with backward direction, fixed effort and a predecessor, in this case task 5

• Set Gather documents task to scheduling direction Backwards, with a predecessor in this case task 4

• Try to change scheduling mode from Gather documents task to fixed effort

• Pop up A cycle has been found, formed by: "Gather documents" -> "Gather documents" but can't do nothing

Is this the intended behaviour?
Thanks,

Arnau

Hi, what is the status of this one? seems to be a critical one, leaves the bryntum application in an unusable state. User can not work on the project anymore.
