[Chameleon] Not usual "update" widget behaviour while updating map - fixed

[Jacob Delfos]

Giuseppe,

That problem has been there for a while. I once fixed it in my own site in version 1.0.4 when I did some debugging, but I never submitted a bug for it. Paul, does a bug exist for it? I didn't find one, but it seemed so obvious that I can't imagine no one else noticed in all that time.

This is what needs to be done:
in UpdateMap.widget.php, line 137, inside the body of the function "clickUpdateMap", the following lines should be added:

------------------------------------------------------------------------------------------------------------------------
    {$this->mszHTMLForm}.MAP_EXTENTS_MINX.value = goCWCJSAPI.oMap.minx;  //custom added, not to lose extents
    {$this->mszHTMLForm}.MAP_EXTENTS_MAXX.value = goCWCJSAPI.oMap.maxx;
    {$this->mszHTMLForm}.MAP_EXTENTS_MINY.value = goCWCJSAPI.oMap.miny;
    {$this->mszHTMLForm}.MAP_EXTENTS_MAXY.value = goCWCJSAPI.oMap.maxy;
    {$this->mszHTMLForm}.NAV_CMD.value = ""
------------------------------------------------------------------------------------------------------------------------


before the line
------------------------------------------------------------------------------------------------------------------------
 {$this->mszHTMLForm}.UPDATE_MAP.value = "1";
------------------------------------------------------------------------------------------------------------------------

This makes sure that whatever was changed in javascript gets saved before it's submitted.

regards,

Jacob

By activating JS-API using the following tags in the template file:

<cwc2 type="cwcjsapi" debug="false"/>
<cwc2 type="SharedResource" name="CWCJSAPI"/>

the "update" widget has a reproducible wrong behaviour: using the zoom
widget a couple of times over the map and then clicking update (wether
or not changing the visible layers) will cause the map-view beeing reset
to the center of the map.

Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are, by
definition, not smart enough to debug it.
