JSONObject does not like javascript date constructor
Hi,
I am not quite sure if this is a limitation of my javascript json
knoledge or a tapestry one. But When I use google's visulisation package
to create json representation of a DataTable
JSONObject.add("jsonDataTable", dataTableJSONString) I get the follwing
exception (full exception at [1]).
character 239 is found at:
,"rows":[{"c":[{"v":new Date(2011,5----THIS IS CHARACTER 239---,23)},,{
It seems like an unescaped date constructor is not recognized as valid
and it just sees the comma (,) and believes a new parameter should be
defined. Is this correct JSON behaviour or is this a tapestry bug?
Cheers,
Joost
[1] the exception:
Expected a ':' after a key at character 239 of
{"cols":[{"id":"date","label":"Date","type":"date","pattern":""},{"id":"budget","label":"Spending
(EUR)","type":"number","pattern":""},{"id":"income","label":"Budget
(EUR)","type":"number","pattern":""}],"rows":[{"c":[{"v":new
Date(2011,5,23)},,{"v":100............ more of the same......
