Our state of the art Gantt chart


Post by Ivan Golov »

Hi,
For the test case, we are using simple plan with 3 wbs elements without any dependencies or resource assignments.
If tasks are automatically scheduled when you change start dates (with constrain no earlier than) or duration critical WBS are highlighted correctly.
If tasks are scheduled manually - when the first task lies on critical path it is highlighted correctly.

If you change date to put second or third task on critical path no tasks are highlited.

We added columns earlyStart(end)date, lateStart(end)date and totalSlack.
Looks like late dates are calculated correctly, but early dates for manually scheduled task aren't changing when you move manual taks, producing unexpected values (some time negative) for totalSlack. If you change sheduling mode to auto, early dates resume to be calculated correctly.

What could affect calcluation of early dates in a way like this? Looks like calculation brakes after 1st task processing.

Hi Ivan,

Could you please attach a runnable test case, so we could reproduce this issue and investigate it? You could use one of our examples as a base. Also please provide the information about Gantt version you used. Your license information says that you are using vanilla Gantt, but your screenshots looks like ExtJS.

Thanks in advance,
Alex.

All the best,
Alex

Hi Alex,
We use React Gantt 2.1.9, skin is intentionally made to match other applictation modules indeed written in ExtJS.
We need some time to provide such example (find a workaround for this situation), as soon as it will be ready I upload it.

I like your skin too! Looking forward to seeing your testcase. Meanwhile you can find a new beta release of 4.0 in the CustomerZone. Feel free to download it to check if the issue is still present. Cheers!
