Our state of the art Gantt chart


Post by jintech »

Hello,
We have recently upgraded our Bryntum Gantt from version 6.1.7 to 6.2.1 and are currently facing a couple of issues:

1- Edit Modal Not Opening When Date Fields Are Required
When we set the required property to true for the date fields, the edit modal does not open. The modal only opens if we set required: false, which is not acceptable in our use case since dates are mandatory.
We have attached a relevant screenshot of the error for your reference:

To reproduce the above issue, you can go to the https://bryntum.com/products/gantt/examples/advanced/
and paste the following code in "features :"

taskEdit: {
            items: {
                generalTab: {
                    items: {
                        startDate : {
                                    label : 'Start date',
                                    type : 'datetimefield',
                                    required : false,
                                    width : '20%',
                                    flex : '1 0 100%',
                                    dateField: {
                                        format: 'DD MMM YY',
                                        triggers : {
                                            back : {
                                                cls : 'fa-light fa-chevron-left'
                                            },
                                            forward : {
                                                cls : 'fa-light fa-chevron-right'
                                            },
                                            expand : {
                                                cls : 'fa-light fa-calendar'
                                            }
                                        }
                                    },
                                    timeField: {
                                        triggers : {
                                            back : {
                                                cls : 'fa-light fa-chevron-left'
                                            },
                                            forward : {
                                                cls : 'fa-light fa-chevron-right'
                                            }
                                        }
                                    },
                                    cls: {
                                        'b-inline': 1
                                    },
                                },
                    }
                }
            }

    },

2- Changes in the Resource Assignment Field UI
We are using the resourceAssignment type for the Assignee column. However, in version 6.2.1, the UI of the resource assignment editor appears different from what we were using in the previous version as a combo.
Could you please confirm if this change is expected or if there is a way to revert to the previous appearance?
We have attached relevant screenshots for your reference:

We would appreciate your suggestions on how to address these issues.

Hi,

Thanks for your report. Regarding the first issue, I've opened a ticket to investigate it. Here is the ticket to track progress https://github.com/bryntum/support/issues/11418

Regarding the second issue, the resourceAssignmentPicker looks the same here https://bryntum.com/products/gantt/examples/advanced/ as before

It's hard to say why that happened without checking how you've made changes to the picker!

Best regards,
Tasnim

The UI of the dropdown has been improved since 6.2.0. The change was somewhat hidden here: https://bryntum.com/products/gantt/changelog/#release-6.2.0

But the picker of the filterField should be configurable to meet you needs, and that is not very easy now. Here is a ticket for that:

https://github.com/bryntum/support/issues/11422

However if you do not want the tbar and bbar, you can hide them:

On the error throw. I pasted the code into the example, and I cannot reproduce the error.

How exactly do you get it to throw?
