Browsing Kepware channels from a mashup

[aiGreek]

Greetings.

I'm trying to create a mashup that allows me to browse Kepware channels and items, like the Discover tab from the industrial thing page on the composer.

I have created "custom" versions of the BrowseItems and BrowseGroups services that allow me to choose an IndustrialGateway to execute said services on the Kepware chosen on the mashup. Their output an infotable with the same Data Shape as their "stock" versions.

I'm trying to use a tree widget to display the channel structure like in the screenshot above, but I cannot find a way to do so correctly. I can display the root and the first levels of the tree (although not in the way I expect):

 

 

but when I try to go deeper into the structure the tree just disappears:

I've tried to use my custom service to change dots into slashes for the FullPath rows, but it didn't help.

Any suggestions?
Thank you for your time.

Hi @aiGreek,

Please find attached some example entities and data for a TreeGrid Advanced that displays 3 levels : 

• Entities_TreeGrid.xml (1 DataShape + 1 DataTable + 1 Mashup)
• data-0.twx (unzip data-0.zip, content of above mentioned DataTable)

I hope that this can help you with your use case by comparing your data / widget configuration / bindings with this example one.
