Indirect binding on parameter not working

[Aiasa21]

Good morning,

I’m trying to create an indirect binding but I’m not able.

I have a parameter path and a custom property in a flex repeater. I want to access to the parameter dynamically using this kind of binding:

I’m pretty sure I’m doing something wrong, I’ve used indirect binding on UDT or tags, but never with parameters.

How should I change it?

I continue searching in the forum and finally I make it works using property() in a normal expression binding instead of using an Indirect Tag Binding.
