Default template not applied automatically

[sylvainfaivre]

Summary

When creating an issue on a tracker other than the default tracker for a project, the template is not applied automatically.

Description

When creating an issue, you can select the tracker in the project.
Let's say you have a project with 3 trackers : tracker1, tracker2, tracker3.
Tracker1 is the default tracker for this project.

If you apply an issue template as default template for tracker1 : when you create an issue, the template is applied.
If you apply no issue template for tracker1, but apply an issue template as default template for tracker2 : when you create an issue, at first the template is not applied, which is OK, because tracker1 is selected by default. Then, when you change the tracker to tracker2, I would expect the default template to be applied, but it is not (altough it is shown and can be selected by the user).

Thank you for contributing to Redmine Issue Templates plugin!' first issue

We face a similar problem.
We hope it will be improved.

Does using code from the 0.3-stable branch cause the same problem?
When updating from 0.3 to 1.0, there was a change to "rewrite the JavaSctipt code from jQuery to plain JavaScript." That may have something to do with it.

[sylvainfaivre]

Well I tried to switch to the 0.3-stable branch and it doesn't seem to work at all : the issue template is not applied, and the "issue template" field is not present in the new issue page, even if I set the template as default for the default tracker.
Is there anything I should be aware to make this version work ?

We do have the same problem on latest master.

Any update on this issue? I have faced the same issue, unable to resolve.

[sylvainfaivre]

A small update on this issue, it looks like a race condition. I reproduced the bug several times, and I noticed that :

• a few times, the template loaded as expected when choosing the tracker
• most times, the template seems to briefly load in the description field before being blanked

Fix in Pullrequest works for reload after change tracker! #63
But if you click on "Do you replace subject and description? - Yes / No" the whole Redmine Header does not work anymore until you save or press F5
