ERP Item tab shows Error dialog, when no connection to ERP Service

[JakobBertagnolli]

When there is no connection to ERP Service and the ERP Item tab gets selected in Vault an error dialog apperes:

This error message is caused by a called function GetCategoryList() inside the ERP Item.xaml file: <ComboBox Name="Category" SelectedValue="{Binding Entity.Category}" DisplayMemberPath="Value" SelectedValuePath="Key" Grid.Column="1" Grid.Row="0" ItemsSource="{Binding DataContext.PsList[GetCategoryList], ElementName=MainWindow}" />

Within this function the commandlet Get-ERPObjects is called and triggers the error dialog: $categories = Get-ERPObjects -EntitySet "Categories"

How to reproduce the issue:

• turn off the powerGate Server
• Open Vault
• Select a file and switch to the ERP Item tab
• The error dialog apperes

Note: Sometimes the error dialog apperes two times because for some reason Datastandard triggerd the OnTabContextChanged() function twice. If Vault gets started and the ERP Item tab was selected automatically, this error dialog will appear 3 to 4 times.

1. I was not able to reproduce this issue. Just the red message in top of the tab was visible to me, but no error window.
2. I had to comment out a codeline in powerGateMain.ps1 to open the Item- and BOM Tab without Datastandard- and powerEvents errors. A check with $dsDiag.Inspect() showed me, that the variable $searchWindow is not available. (see below)

Please advise!
