Hi Maybe its because Sunday and i am bit fuzzy but i am struggling to make a popup parameters work when there is template repeater. I got basics covered: 1 There is on click action behind template to open popup with passing UDT parameter configured 2 popup root container does have matching custom parameter of UDT type When i click on the any instance inside template repeater i got messages "Cannot assign orphaned UDT instance to a component property: Root Container" I have no problem passing integer parameter via popup but UDT does not work. Also passing UDT without template repeater did work in the past. Any suggestion how to troubleshoot it? ---

No can do. You're simply unable to pass udt types to a popup, which is one of the many reasons not to use UDTType parameters at all. Just pass the tagpath to the UDT instance instead to the popup (and to the Template too) ---

> [@nminchin](#): > > Just pass the tagpath to the UDT instance instead to the popup (and to the Template too) how is this supposed to work in practice. I have template repeater with instances inside? do i need to create custom property on template repeater? Any chance for simplest example please? ---

Your template params dataset should be a list of the tag paths to the UDT instances, and the column name should match the tag path parameter in your templates. Eg `deviceTagPath` ---

What I thought I could do was make a template that is just contains a slightly dressed Multi State Indicator: slimming the style to take just 0 or 1 as values and binding text in the indicator to be the Name property of the dropped-in tag.
