Subject RE: JSON Property
Date Tue, 04 Jan 2011 14:09:10 GMT
I don't want to use a separate roundtrip for loading the jqGrid for two reasons:
1. I want to handle the contents of the grid, and additional fields, in a single transaction.
2. It's inefficient and unnecessary.
Obviously the first is the more important :)

Pardon me if I'm probably wrong, but why can't you use JSON action?
I mean, something like this:

[...] jQuery("#list2").jqGrid({ url:'YOUR_JSON_ACTION_URL', [...]

record with children (the children being in the jqGrid and set via JSON) submitted as a single
entity (I typically put the JSON data into a hidden field and then update it in the submit,
but there are also other uses for the JSON data, such as selection lists, that don't get updated).
