Hi Andreas,
This is a tricky one: the layerNames come from the config.xml of the
app. Example: wfs-t:
<OverviewMap id="locatorWidget">
<htmlTagId>locatorMap</htmlTagId>
<width>180</width>
<layers>
<layerName>basic</layerName>
<layerName>topp:tasmania_water_bodies</layerName>
<layerName>topp:tasmania_roads</layerName>
<layerName>topp:tasmania_cities</layerName>
</layers>
</OverviewMap>
For this to work on layers that have an @id, you would have to replace
the node value of the corresponding layer name with the value of the
layer id.
Is that desired functionality? Or should we create a fail safe mechanism
for this as well? Like: try to find the oLlayer by the value of that
node, if not, find the layer in the context, retrieve its @id value and
try to find the oLlayer with that @id.
This leads me to question whether or not we should generate our own @id
at all (in OwsContext for example) when there is none...
Please give me your opionion.
Regards,
Roald
There is no failsafe mechanism in fetching the oLlayer by layerName
