[mapguide-users] Create programmatically a map

[sekko970]

Dear all,
I just found the cause of my problem.

My web-layout xml template is a copy of a new layout XML structure created
from MGMaestro:

<?xml version="1.0" encoding="utf-8"?>
<WebLayout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:noNamespaceSchemaLocation="WebLayout-1.0.0.xsd">
	<Title>MyMapTitle</Title>
	<Map>
		<ResourceId>MyMap.MapDefinition</ResourceId>
		<HyperlinkTarget>TaskPane</HyperlinkTarget>
	</Map>
	<ToolBar>
		<Visible>true</Visible>
		<Button xsi:type="CommandItemType">
			<Function>Command</Function>
			<Command>Print</Command>
		</Button>
                          .............
	</ToolBar>
	<InformationPane>
		<Visible>true</Visible>
		<Width>200</Width>
		<LegendVisible>true</LegendVisible>
		<PropertiesVisible>true</PropertiesVisible>
	</InformationPane>
	<ContextMenu>
		<Visible>true</Visible>
		<MenuItem xsi:type="CommandItemType">
			<Function>Command</Function>
			<Command>Select</Command>
		</MenuItem>
                         .............
	</ContextMenu>
	<TaskPane>
		<Visible>true</Visible>
		<Width>280</Width>
		<TaskBar>
			<Visible>true</Visible>
			<Home>
				<Name>Home</Name>
				<Tooltip>Return to home task page</Tooltip>
				<Description>Return to home task page</Description>
				<ImageURL>../stdicons/icon_home.gif</ImageURL>
				<DisabledImageURL>../stdicons/icon_home_disabled.gif</DisabledImageURL>
			</Home>
			<Forward>
				<Name>Forward</Name>
				<Tooltip>Forward to next task page</Tooltip>
				<Description>Forward to next task page</Description>
				<ImageURL>../stdicons/icon_forward.gif</ImageURL>
			
<DisabledImageURL>../stdicons/icon_forward_disabled.gif</DisabledImageURL>
			</Forward>
			<Back>
				<Name>Back</Name>
				<Tooltip>Return to previous task page</Tooltip>
				<Description>Return to previous task page</Description>
				<ImageURL>../stdicons/icon_back.gif</ImageURL>
				<DisabledImageURL>../stdicons/icon_back_disabled.gif</DisabledImageURL>
			</Back>
			<Tasks>
				<Name>Tasks</Name>
				<Tooltip>Task list</Tooltip>
				<Description>View a list of available tasks</Description>
				<ImageURL>../stdicons/icon_tasks.gif</ImageURL>
				<DisabledImageURL>../stdicons/icon_tasks_disabled.gif</DisabledImageURL>
			</Tasks>
			<MenuButton xsi:type="CommandItemType">
				<Function>Command</Function>
				<Command>Measure</Command>
			</MenuButton>
                                      .............
		</TaskBar>
	</TaskPane>
	<StatusBar>
		<Visible>true</Visible>
	</StatusBar>
	<ZoomControl>
		<Visible>true</Visible>
	</ZoomControl>
	<CommandSet>
		<Command xsi:type="BasicCommandType">
			<Name>Pan</Name>
			<Label>Pan</Label>
			<Tooltip>Pan mode</Tooltip>
			<Description>Drag the map to view areas out of range</Description>
			<ImageURL>../stdicons/icon_pan.gif</ImageURL>
			<DisabledImageURL>../stdicons/icon_pan_disabled.gif</DisabledImageURL>
			<TargetViewer>All</TargetViewer>
			<Action>Pan</Action>
		</Command>
                          .............
	</CommandSet>
</WebLayout>


If the XML layout definition contains a <button> node chilld of <toolbar>
node, or a <MenuItem> node chilld of <ContextMenu> node, or a <MenuButton>
chilld of <TaskPane><TaskBar> node, or a <Command> node chilld of
<CommandSet> node, it is generated the following error:

The type 'OSGeo.MapGuide.MgNullArgumentException' nell'assembly
'MapGuideDotNetApi, Version = 2.0.2.3011, Culture = neutral, PublicKeyToken
= null' is not marked as serializable.


How can I fix it?
Thanks in advance.
Fabio
