Re: error loading root children

Hi Jared,

Thanks for explaining this!  I gave the object a name (the identifier prop name for this structure) and type, and it works now.

Cheers,

Greg

A nested object in an item is treated as another item.  See:

 In this case, you declare the identifier, then have an item that
doesn't have an identifier.  The load of that structure will fail in
the store.

Hi,

I use the JSON below to create an ItemFileReadStore, which I then use to
create a ForestStoreModel, which I use to create a Tree.  When I leave
out the 'months' property in the item with 'name' : 'RFE', it works
perfectly.  But, when 'months' refers to an {}, I get the following error:

 [Widget dijit.Tree, dijit_Tree_0] _connects=HTMLDivElement
_deferredConnects=Object : error loading root children:  TypeError: _48
is undefined message=_48 is undefined

I've tried using:

{
   'name' : 'RFE',
   'type' : 'dataset',
   'periodicities' : [ 'daily', 'dekadal', 'monthly' ],
   'selectedPeriodicity' : 'monthly',
   'units' : [ 'raw', 'percent', 'zscore', 'mmdifference', 'spi' ],
   'selectedUnits' : 'raw',
   'months' : {}
 }

as a test, and this doesn't work, either.  Is it permissible to have a
nested object in an item?

Here's the complete JSON:

{
 identifier : 'name',
 label : 'name',
 items : [
 {
   'name' : 'All Africa',
   'type' : 'region',
   'children': [
   {
     '_reference' : 'RFE'
   },
   {
     '_reference' : 'TPW'
   },
   {
     '_reference' : 'NDVI'
   },
   {
     '_reference' : 'WRSI'
   }
   ]
 },
 {
   'name' : 'East Africa',
   'type' : 'region',
   'children': [
   {
     '_reference' : 'RFE'
   },
   {
     '_reference' : 'TPW'
   },
   {
     '_reference' : 'NDVI'
   },
   {
     '_reference' : 'WRSI'
   }
   ]
 },
 {
   'name' : 'West Africa',
   'type' : 'region',
   'children': [
   {
     '_reference' : 'RFE'
   },
   {
     '_reference' : 'TPW'
   },
   {
     '_reference' : 'NDVI'
   },
   {
     '_reference' : 'WRSI'
   }
   ]
 },
 {
   'name' : 'South Africa',
   'type' : 'region',
   'children': [
   {
     '_reference' : 'RFE'
   },
   {
     '_reference' : 'TPW'
   },
   {
     '_reference' : 'NDVI'
   },
   {
     '_reference' : 'WRSI'
   }
   ]
 },
 {
   'name' : 'RFE',
   'type' : 'dataset',
   'periodicities' : [ 'daily', 'dekadal', 'monthly' ],
   'selectedPeriodicity' : 'monthly',
   'units' : [ 'raw', 'percent', 'zscore', 'mmdifference', 'spi' ],
   'selectedUnits' : 'raw',
   'months' : {
     '2003' : 'all',
     '2004' : 'all',
     '2005' : 'all',
     '2006' : 'all',
     '2007' : 'all',
     '2008' : [ '1', '2', '3', '4', '5', '6', '7' ]
   }
 },
 {
   'name' : 'TPW',
   'type' : 'dataset',
   'periodicities' : [ 'daily', 'dekadal' ],
   'selectedPeriodicity' : 'dekadal',
   'units' : [ 'raw', 'percent' ],
   'selectedUnits' : 'percent'
 },
 {
   'name' : 'NDVI',
   'type' : 'dataset',
   'periodicities' : [ 'daily', 'monthly' ],
   'selectedPeriodicity' : 'daily',
   'units' : [ 'raw', 'percent', 'spi' ],
   'selectedUnits' : 'spi'
 },
 {
   'name' : 'WRSI',
   'type' : 'dataset',
   'periodicities' : [ 'dekadal', 'monthly' ],
   'units' : [ 'raw', 'percent', 'zscore', 'spi' ],
   'selectedUnits' : 'zscore'
 }
 ]
}

Any thoughts?

Thanks!

Greg
