Creating InfoTable Problem

[lwei]

Hi, guys!

I've got some problems when I create a infotable.

Here is the following service I use:

var infotable1Object = {dataShape: {fieldDefinitions :{} }, rows: [] };

infotable1Object.datashape.fieldDefinitions['name']={name: 'name', baseType: 'STRING'};

infotable1Object.datashape.fieldDefinitions['value']={name: 'value', baseType: 'STRING'};

var newROW= new Object();

newROW.name="abcde";

newROW.value="12345";

infotable1Object.rows[0]=newROW;

var params = {

  json: infotableObject /* JSON */

};

// result: INFOTABLE

var result = Resources["InfoTableFunctions"].FromJSON(params);

the result is always:

TypeError: Cannot read property "fieldDefinitions" from undefined (CreateInfo#1)

The easiest way to create an infotable would be to define a DataShape and then use CreateInfoTable from DataShape

Fool Proof that way!

If you do a straight up infotable, use AddField instead of the definitions as you are calling.

I believe someone posted a really nice piece already in the community or in a blog on infotables.

Hi, Pai.

Thanks for the information, but the isn't from me.

It is from PTC, thingworx market's  CSV file.

There is a PDF file that show me the example of how to write a CSV file.

But it just can't work. I'm confused.

Lee, another quick thing - you've used var infotable1Object, but in the json content you've used infotableObject instead.

Hi, Aanjan

  After I fix the bug, it stills result TypeError: Cannot read property "fieldDefinitions" from undefined (WriteCSV#3)
