dynamic layers for my search results

[Tania Kirov]

Hello,
I’m looking at creating dynamic layers for my search results. If you
have any info/documentation/explanation how it could be done with
OpenScales it will be highly appreciated
Thank you
Regards,

I thought I should give a bit more details what I’m tying to do :

I would like to be able to generate a layer which contains just a
specific entities/features. I’ve already have a layers defined in
Geoserver that contains all the features. There is a search screen in
my application which generates a list of features and I want to be
able to provide a map with only those features on it. I thought I
could use a WMS getFeature request passing a filter containing the
features’ Ids, but I do not see how this can be done in OpenScales.

Can you give me any guides how can I achieve this and if I need to do
an “extension” to OpenScales how should I do it, so I can submit my
changes after that?

Thank you

Tania

Hi,
You may try with CQL_FILTER:
var layer:WFS = new WFS();
(layer.params as WFSParams).setAdditionalParam('CQL_FILTER',
'YOUR_CQL_FILTER');

I thought CQL was not supported. Is that a new feature in 1.2 release?

Hi,
it's not supported as there is no specific interface for it, but you can
force CQL in your requests as you can hardcode it in OGCParams/WFSParams

Thank you for your reply Simon.

I’ve tried the additional WFSParams.setAdditionalParam() but it gives
me an error: "bbox and cql_filter both specified but are mutually
exclusive".
The issue is that in WFS.redraw() there is:
this.params.bbox = projectedBounds.boundsToString();
which inserts the BBOX in my request parameters. I do not have control
over this, so how can I make it check/notify that I do not want the
BBOX parameter.
I’ve tried commenting out just that line in the code of WFS.redraw()
and my request came through properly, containing the right results.
