followed the doc on Dynamic Mapfile Modification :</SPAN></FONT></DIV>
<DIV><FONT face="Times New Roman">
<P align=left>The standards steps to use this mechanism are:</P>
<P align=left>1. Create all the needed elements and combine them together in a
</FONT><FONT face=Courier size=2>MapOverlay </FONT>or a<SPAN
class=305185605-19052006> </SPAN><FONT face=Courier size=2>LayerOverlay
</FONT><FONT face="Times New Roman">instance.</P>
<P align=left>2. Call the </FONT><FONT face=Courier size=2>updateMap()
</FONT><FONT face="Times New Roman">function. The function returns a
</FONT><FONT face=Courier size=2>MapOverlay </FONT><FONT
face="Times New Roman">instance.</P>
<P align=left>3. If needed, use the result instance to retrieve an index or a
element name.</P>
<P align=left><SPAN class=305185605-19052006><FONT face=Arial color=#0000ff
size=2>Once the modification is made, the map is updated and saving the map
file (<FONT face=Courier
size=1>this->serverContext->getMapObj()->save('/tmp/debug.map');</FONT>)
is fine. But when I zoom again, cartoweb is loading the initial mapfile and I
lose my plugin' changes. </FONT></SPAN></P>
