I’m trying to use DataProcessor with my Gantt chart with setUpdateMode(“off”) setting (I want to send all the updates once user hits ‘Save’ button).
var dp = new gantt.dataProcessor(url);
dp.init(gantt);
dp.setTransactionMode("JSON");
dp.setUpdateMode("off");
However I encountered one problem. When I update 3 tasks and then create 1 link, only one request (for link creation) is sent (using dp.sendData()). If I do it in reverse order - first create link and then update 3 tasks - then 3 requests (for modification of 3 tasks) are sent, but not for the link creation.
So my question is - is this a standard behaviour of the dataProcessor? is there some way how to get around this and send all updates (including tasks and links) at once?
Hello,
Thank you for informing about the issue. Looks like it is a bug. I added it to our internal tracker. The dev team will fix it in the future, but I cannot give you any ETA.
I have the following example with the custom routing where the data is saved in an object with arrays, and you can manually send that data via custom methods: https://snippet.dhtmlx.com/5/321546e47
thank you for your answer. That was exactly my intention, before I started this topic - to use a custom router to collect the updates and send them later manually. I just wanted to be sure, there is no other way…
You can do this to send to your server side tasks and links in 2 requests
dp.setGanttMode(“tasks”);
dp.sendData();
dp.setGanttMode(“links”);
dp.sendData();
