Importing of GML Files / Districts without Coordinates

Support - Assistance technique
1

Hi,

We’re importing GML files into a DHIS 2 instance and there are a couple of districts that we don’t have coordinates for yet. We’ve uploaded what we have successfully and the mapping looks great.

However, if we have a pivot table with data points included from the two districts that we don’t have coordinates for then view it as a map, the entire map does not load at all and gives a javascript error "Cannot read property ‘length’ of null in core.js. (util.map.getTransformedFeatureArray function). There is no messaging to the user of why the map does not load. Of course we could manually exclude these two districts from the table and it will work, but this is not ideal or intuitive for the users of the system.

What can we set the coordinates to for these two districts in the meantime so that the rest of the map will not break? We’ve tried setting it to null, empty string, and ‘[[[]]]’.

Thanks,

Lorill

Hi Lorill,

Which DHIS version are you running?

What did you put in the Featuretype field?

Sorry - forgot to mention this is 2.22 r 21826.

In the featuretype field we have tried both null and ‘NONE’.

Seems like a hack, but I would try and set it to “POLYGON”.

The client will likely accept these empty polygons, but that would be the correct type in this case.

Not ideal, but maybe give it a try.

Hi Lorill,

I am actually not able to reproduce it. I tried this:

  • Removed coordinates and feature type for one district

  • Created a pivot table and selected one district with coordinates plus the one without

  • Opened it as map

→ The map shows up containing only the district with coordinates

I also tried setting different combinations of NULL/[[]]/ as coordinate and NULL/NONE/ as featuretype, but never managed to get that error message.

Version 2.22, rev 21892.
