Smart methode to push data in a JSON string into a DataSource for a ColumnTree ?

[zeddicus]

Hello together,

I'm just wondering, if there exists a smart way to get the data from a JSONvalue in a DataSource object which I use for a ColumnView.

In the moment I convert the JSONvalue in a string, then in a javascript object and at last in a Record array with the following code line (where 'data' is the JSONvalue):

final Record[] records = 
     Record.convertToRecordArray(JSON.decode(data.toString()));

Then I push the Record array into the DataSource object with the setTestData methode :

 datasource.setTestData(records);

Seems to work fine, but I have two questions:

First, do any restrictions exists on the setTestData methode, like length of the array ?

And second, exists there a smarter way to do this ?

Thx in advance,
Zed

Yes, there exist multiple, much smarter ways to do this. Start by reading the QuickStart Guide, specifically, the chapter on Data Integration.
