Hi, How do I assign components to an issue when creating it?

I'm currently sending:

[IssueEN xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"] [IssueID]0[/IssueID] [ProjectID]171[/ProjectID] [ProjectCode][/ProjectCode] [IssueTypeDesc][/IssueTypeDesc] [IssuePriorityDesc][/IssuePriorityDesc] [IssueSeverityDesc][/IssueSeverityDesc] [IssueStatusDesc][/IssueStatusDesc] [IssueResolutionDesc][/IssueResolutionDesc] [ReportedByUsername][/ReportedByUsername] [FixedInVersionName][/FixedInVersionName] [IssueType]1[/IssueType] [IssuePriority]2[/IssuePriority] [IssueSeverity]5[/IssueSeverity] [IssuePrioritySequence]0[/IssuePrioritySequence] [IssueSeveritySequence]0[/IssueSeveritySequence] [IssueStatusSequence]0[/IssueStatusSequence] [IssueStatus]4[/IssueStatus] [IssueResolution]5[/IssueResolution] [ReportedBy]8[/ReportedBy] [FixedInVersion]0[/FixedInVersion] [IssueSummary]summary[/IssueSummary] [IssueLongDesc]description[/IssueLongDesc] [DateRevised]2008-11-24T12:00:00[/DateRevised] [IssueKey][/IssueKey] [FixedInVersionNumber]0[/FixedInVersionNumber] [FixedInVersionDesc]0[/FixedInVersionDesc] [FixedInVersionOrder]0[/FixedInVersionOrder] [FixedInVersionArchived]false[/FixedInVersionArchived] [FixedInVersionReleased][/FixedInVersionReleased] [StartDate]2008-11-24T12:00:00[/StartDate] [DueDate]2008-11-24T12:00:00[/DueDate] [ResolvedDate]2008-11-24T12:00:00[/ResolvedDate] [ClosedDate]2008-11-24T12:00:00[/ClosedDate] [RiskLevel]1[/RiskLevel] [Votes]0[/Votes] [EstimateHours]0[/EstimateHours] [EstimateMinutes]0[/EstimateMinutes] [RiskLevelDesc][/RiskLevelDesc] [Visibility]1[/Visibility] [VisibilityMemberType]GlobalGroup[/VisibilityMemberType] [ParentIssueId]0[/ParentIssueId] [IssueComments xsi:nil="true"][/IssueComments] [IssueCustomFieldData xsi:nil="true"][/IssueCustomFieldData] [IssueTimeEntries xsi:nil="true"][/IssueTimeEntries] [AffectedVersion xsi:nil="true"][/AffectedVersion] [IssueResources xsi:nil="true"][/IssueResources] [Components] [ComponentEN] [ComponentID]745[/ComponentID] [ProjectID]171[/ProjectID] [ComponentName]Reporting[/ComponentName] [ComponentDesc]Imported from trac[/ComponentDesc] [ComponentReadOnlyS]N[/ComponentReadOnlyS] [UserID]13[/UserID] [ParentComponentID][/ParentComponentID] [ComponentReadOnly]false[/ComponentReadOnly] [ComponentLead xsi:nil="true"][/ComponentLead] [DateCreated]2009-11-06T11:58:45[/DateCreated] [TimeStamp]AAAAAAAASyg=[/TimeStamp] [/ComponentEN] [/Components] [ComponentsName]0[/ComponentsName] [ComponentsDesc]0[/ComponentsDesc] [ComponentsID]745[/ComponentsID] [IssueTypeImagePath]0[/IssueTypeImagePath] [IssuePriorityImagePath]0[/IssuePriorityImagePath] [IssueSeverityImagePath]0[/IssueSeverityImagePath] [IssueStatusImagePath]0[/IssueStatusImagePath] [HasRestrictedVisibility]false[/HasRestrictedVisibility] [HasCommentsWithRestrictedVisibility]false[/HasCommentsWithRestrictedVisibility] [IsSubIssue]false[/IsSubIssue] [IsParentIssue]false[/IsParentIssue] [DateCreated]2009-07-01T10:46:31[/DateCreated] [TimeStamp]AAAAAAAAC74=[/TimeStamp] [/IssueEN]

Where components are in the [Components] tag, these are the results from a create component command so I'm not sure if they contain too much or too little info for assignment.

However, in the response the components and componentID fields are empty:
