Hi All,
I have an issue.
When assigning a resource to a task and pressing undo/redo it only gives the resources being added or removed in the modelList prop.
there is no oldData prop to compare the changes in the queue.
I have to send the request to the backend with updated assigned resources and because there is no oldData to compare I cannot generate a new list with updated resources.
Hi Alex
Sorry, I didn't get your point here. What do you mean by
Why don't you use ProjectModel/Store level to handle data changes?
I am trying to implement functionality for undo-redo and I am getting all the changes from STM.
I don't see the point of using ProjectModel/Store for undo-redo functionality when we have STM for it.
Can you please explain a bit more? Thanks
Don't we talk about saving data on server? STM just manage state, but all data change tracked by ProjectModel and persisted in projectModel.changes property and can be cached with https://bryntum.com/products/gantt/docs/api/Gantt/model/ProjectModel#event-change event.
Maybe I misunderstood the use case?
All the best,
Alex
Yes, you are right about the part of saving data on the server.
The thing I am trying to say is that when we press the undo button an event is fired with a transaction from STM and then I can update the data accordingly on the server.
If I don't have enough data in STM transactions I won't be able to save data on the server properly.
What you are trying to say is that I should get the changes from projectModel. In that case, I would not know which change should I get because I won't know what the user is trying to undo or redo.
Hi Ahmad,
I have opened a feature request for this here https://github.com/bryntum/support/issues/8848. You can subscribe to it to keep track of updates.
