Hi Bart,

Can you tell me where the form variable (SCALE) is used in calculations
in JSAPI mode? If I can see it is used only in:


If this is true, may I just
instead of above and use something like:

"{$this->mszHTMLForm}.SCALE.value = Math.round(goCWCJSAPI.oMap.scale);"
for displaying the rounded scale?

regards, dejan
