Our state of the art Gantt chart


Post by daniel.piret »

Hello Support,

I tried loading Gantt of the attached file in 4.2.0 version. It does not load and gives the error - https://prnt.sc/1izxxbp

I have attached two json files. One which is working and the other that is not. The only difference between the two is the following dependency:

 
 {
        "id": 512508,
        "fromTask": 1351464,
        "toTask": 1351476,
        "type": 2,
        "lag": "0",
        "lagUnit": "day"
 }

If the above dependency is added, Gantt does not load.

I think this is similar to the viewtopic.php?f=52&t=18005&e=1 issue.

Can you please help us?

This json is not working. The only difference between the working file and this file is the addition of dependency.

Task "Task causing issue" Start No Later Than August 2, 2021, 12:00 AM constraint is conflicting with Dependency (End-to-Start) from "Summary causing issue" to "Task causing issue".

Since the upcoming 4.3.0 release (or 5.0.0 ..not sure which version it will be called) handling of such issues will be much simpler:

Hello Support,

Is there any general rule to keep in mind to avoid such issues temporarily until its solved?

Thanks.

Generally speaking all Start/Finish no later than and Must Start/Finish On constraints could potentially result scheduling conflicts. So need to be careful when using them.
