Hi Bryntum team,
I'm encountering an issue when using the Gantt component (v5.5.2) in my application. Whenever I attempt to load a project using project.loadInlineData(), I get the following error in the console:
Uncaught TypeError: Cannot read properties of undefined (reading 'isProject')
at Gantt.js:1023
Here’s a simplified version of my setup:
const project = new ProjectModel({
tasksData: [
{ id: 1, name: 'Project', expanded: true, children: [
{ id: 2, name: 'Task 1', startDate: '2025-04-01', duration: 5 },
{ id: 3, name: 'Task 2', startDate: '2025-04-06', duration: 3 }
]}
],
dependenciesData: []
});
const gantt = new Gantt({
adopt: 'gantt-container',
project
});
I’ve double-checked the task structure and data format, but I can’t figure out what’s causing the issue. This error started happening after I upgraded from v5.4.0 to v5.5.2. Am I missing something in the configuration? Has there been a change in how the project model should be initialized?
