Getting updated Point Geometry from a DataSource

avitran0

i am building a custom widget for arcgis experience builder.

i am capturing the selected records (point geometries) from a data source, and need to get the amount moved after it was updated.

i can retrieve the geometry from all records before they were updated just fine.

after one is updated, just that one seems to lose its geometry information, and `DataRecord.getGeometry` returns `null`.

why exactly is that, and how can i retrieve the geometry again?

Hi @avitran0 ,

Whether selected records include geometry depends on whether the widget requests geometry when updating them. If geometry is missing and you still need it, you can explicitly query for it using returnGeometry: true, for example:

const recordsWithGeometry = await ds.getMainDataSource().query({  
  where: '1=1',  
  outFields: ['*'],  
  returnGeometry: true,  
  objectIds: selectedRecords.map(r => parseInt(r.getId()))  
})  

 

Please let me know if you have any questions.

Thanks,

Yueyang
