Upload GPX - several issues

[andrixnet]

In newcache, when I select a GPX file it automatically triggers an upload. Same result if I press the button next to it.
Should something be wrong, there is a validator that checks the GPX.
If the result of the validation is "not valid", an error message is shown.

The problem is that the error message is shown in the page for like ... 3 seconds.
Error messages that bubble like this and dissapear are the worst from UI standpoint. They leave the user confused after they dissapeared.

The error message should stay until the state of things change.
In this context:

• a new, valid GPX is uploaded
• the field is cleared (no UI exists at this time)
• the field is ignored by the user, as it is not (by design) submitted with the form (specific case given the context)

---

Upon upload of a validatable GPX, a green message is shown also in bubble style which dissapears. It should remain as acknoledgement, until state change.

A modal window openes with list of points in GPX, one can click a point to auto-fill several fields.

• Problem 1: upon selecting (click) a point to be filled, the modal window remains open. It should close, the selection is over, user wants to proceed to next step.
• Problem 2: region is not updated. by default, when manually editing coordinates, the region is updated from internal database. here the coordinates change programatically and the UI onchange event is likely not fired. Additional user interraction is needed, but in a complex way: user has to either choose region manually or change coordinates manually and then change them back. "region from coordinates" button has only informative functionality
• Problem 3: when the user closes the modal window, it is closed with some sort of animation, which at least to some users is dizzying. I would like to request that this animation be removed.

• The autohide of error/success message (5 seconds, not 3) was introduced to minimise confusion of user when he/she doing another changes in the form and the message is still visible ;). It can be easily changed to stay until another GPX is loaded or so, but this behaviour is independent of whether the message is an error or a success one.
• The modal window with list of points in GPX should disappear after selection and it usually does. The problem is when there are no attributes in selected cache, then the javascript exception is thrown and the script does not end. This will be fixed.
• The animations during modal window hiding will be removed. The animation during GPX format window hiding will be "mitigated" as well, to be less absorbing.
• The region is updated every time the new GPX is loaded, but when a region is not found in internal database for update, the previous values stay. This will be changed to load default values (ie. the ones set in the starting, empty form), when the region is not found.

I have these improvements almost implemented now, will try to make a PR in the next few days.
