cate Progress indicator and cancelling no longer working when downloading datasets to local

Expected behavior

@forman When downloading a dataset to local, expect to see download progress and be able to cancel if needed (as before)

Actual behavior

Dataset is still downloaded, but progress bar doesn't get filled in. progress_bar

When a second dataset is downloaded, no cancel button is visible progress_bar_5

Steps to reproduce the problem

Start to download a dataset to local. Example is given below.

progress_bar_2

Look at Tasks panel, see that download progress is not shown
Look in local datastore folder, see that files are being downloaded.
Wait for download to complete, then download a new dataset, e.g.:

@forman This is no longer happening with cate-2.0.0-dev.9 This can be closed.

@forman @hans-permana, @papesci This one's re-appeared in cate-2.0.0-dev.15. Seen with both Windows and Mac machine.

hi all @papesci @forman @hans-permana This one's still happening with dev.19, please move it back from "Done" to the "To-Do" list, thanks.

thanks @forman ! @forman @papesci @hans-permana here's some more info : with cate-2.0.0-dev19 the issue only happens when you are downloading with a regional constraint applied. When you don't have any regional constraint, the progress displays correctly and you can cancel.

@HelenClifton thanks for point this out. This makes be believe that it is an issue in the data access component, with incorrect usage of the progress monitor. I'll assign therefore to @papesci

@forman @HelenClifton @hans-permana Hi Normam the progress bar looks good when execution the copy from the CLI. To test it I have forced to print out each progress increment just to count the number of time it is called

progress

Thanks @papesci @forman @Evadzi . I've tested this with 2.0.0-dev.23 using SST, Cloud and aerosol datasets and confirm it is fixed. Closing it.

@papesci @HelenClifton @Evadzi At least I have not changed any code. It must be the sequence of steps that causes this problem randomly. I'll reopen it until we found out what's the root cause.
