[OpenLayers-Dev] editing tool on multiple layers

[Mohammed Rashad]

I have two layers
layer1
layer2
both are editable vector layers

for layer1 is point layer and layer2 is poygon layers
I had registered some events. both are sharing same events but the behaviour
of events is different
for example

layer1.events.register("featureadded",'',FeatureAdded);
function FeatureAdded(){
alert('layer1');
};
layer2.events.register("featureadded",'',FeatureAdded);
function FeatureAdded(){
alert('layer2');
};

how to define the function as local to a specific layer so that I can use
the same function defined twice whose defenition is different.?

Can I remove the function from the code dynamically?

How to register a function local to the layer.
I will dynamically change the layer using checkboxes which are not part of
OpenLayers.
when I check the checkbox

I can do the following
    Toggle layer visibility
    destroy controlpanel and create tie it to the new layer (say layer 2)

I redefined the functions for featureadded event (FeatureAdded) but the old
function is in use not the redefined one
How can I use the newly defined FeatureAdded function for a featureadded
event after changing the layer

I think some questions are not related to OpenLayers. if so forgive me


Any help will be greatly appreciated
