Hi,

I have written a write to tag script under the property change script of a template when one of the template parameter (which is an input text field) changed.

However, when i run in client mode, it does not trigger the property change at all. And when in preview mode, if i clicked onto the input text field box to key in some texts, it also doesn’t trigger the changes.

It only worked in preview mode if i change it in the property editor.

Please help!

If the text box is trying to change a parameter on the template level, make sure the bindings are bi-directional and the property change script is at the template level.

Thanks nick.

Missing checking onto the bi-directional.

It works now!
