I'm trying to set default action in ajax viewer to be PAN instead of SELECT.
So, I did in web layout URL for home task in task pane pan.php , and pan.php
looks like:
function OnPageLoad()
{
parent.parent.mapFrame.ExecuteMapAction(4);
}
I tried also other actions, but anyway, I get error:
parent.parent.mapFrame.ExecuteMapAction is not a function
So, what is wrong with this, and is there any other way to set default

Hi all. I'm stuck with eastern european characters (č,š,ž,đ) and Oracle. I tried different NLS_LANG parameters on client (which is also the server), and always have some kind of errors.

So, where does some charset conversion take place? Here is my setup: MGOS and Oracle on same machine, all regional settings and languages on croatian, database charset WIN1250 (I can't change this because of possible data loss).

But this returns the following:
Null reference.Null reference. Exception occurred in method MgMap.GetService
at line 93 in file
d:\buildforgeprojects\mapguide_open_source_v2.0\build_23.8\mgdev\common\mapguidecommon\MapLayer/Map.cpp
What is wrong here?

Well, I followed thread from few days ago, someone had same problem. The
solution is that View must have primary key to be selectable. If you are not
too familiar with this, you can use Haris's FDO2FDO Tool, then you read
Oracle source, select the view and just click Create Primary Key. It worked
for me, I hope it will work for you too.
Of course, I aasume that you use King.Oracle FDO provider
