[Cartoweb-users] Dynamic Mapfile Modification

[François Prunayre]

Hi list, one question about dynamic mapfile modification. Aim is to change some metadata element of a layer (eg. wms_sld_url) and keep them alive for a session ...

 

I followed the doc on Dynamic Mapfile Modification :

The standards steps to use this mechanism are:

1. Create all the needed elements and combine them together in a MapOverlay or a LayerOverlay instance.

2. Call the updateMap() function. The function returns a MapOverlay instance.

3. If needed, use the result instance to retrieve an index or a element name.

Once the modification is made, the map is updated and saving the map file  (this->serverContext->getMapObj()->save('/tmp/debug.map');) is fine. But when I zoom again, cartoweb is loading the initial mapfile and I lose my plugin' changes.

Do  I have to save all modifications made by my plugin in session, and apply them every time to solve my issu ?

Thanks for your help.

Francois
