[OpenLayers-Users] GeoJSON layer and modifyFeature control

[Adorian Ardelean]

Hi Eric,

No...it is not working yet. There is some improvement indeed: I can see now
the selection style, but vertexes are still not editable.

I have tried to adapt the suggestion in post I have mentioned earlier.

var styleMap = new OpenLayers.StyleMap();

var rules = [new OpenLayers.Rule({
symbolizer: template,
elseFilter: true
})];
styleMap.styles["default"].addRules(rules);

Using this the edit polygon works!!!. However, I did not figured out how to
include "context" within this. Select style is also not visible (but I do
not mind this, I can most probably find a work around for selection style).

Initially I have used:
var mystyle = new OpenLayers.Style(template, {context: context});
var styleMap = new OpenLayers.StyleMap(mystyle);
And context worked fine.

Any hints on how to include context with rules?

Thank you,
Adorian
