strange POST parameters

[kccheng]

Hi,

I had successfully connect PatternReuseSample (from Showcase) to
PHP backend using Fetch/Update/Add/Remove interface.
However, sometime when I play with the LiveGrid's grouping/sorting/... features,
and try to modify the data via DynamicForm ... my PHP will receive
parameters as below:

$399 = 0_5
$42c = isc_OID_4_groupTree
isFolder = null

I thought all POST parameters pass to PHP should be prefixed by "_", am I correct ?
Where are those parameters come from ? How can I remove them ?
Specially, the "isFolder" parameter ... I did not define this as my RestDataSource field !!

Where can I find the list of "reserved" POST parameters which will send to PHP ?
Thanks a lot.

If those are inconvenient to ignore on the server side, you could override dataSource.transformRequest() to remove any data in dsRequest.data that doesn't have a corresponding DataSource field.

Hi,

Well, it's not difficult to remove them in PHP.
But it will be better if I know what's meaning of those parameters,
and when will those parameters been used ?
Any document for those parameters ? Or, could I assume they are
useless in REST based data binding ? Thanks a lot.

Yes, assume they are useless. They are internal state that is being tracked on the client-side only, and we will be adding a behavior to optionally omit them automatically.

That will be great, thanks.
