title: Unable to get TEdit to connect with dataset under Livebindings when setting datasource.dataset at runtime
body: <p>How do I get controls other than TStringGrid to work properly with Livebindings when the Dataset property of their Datasource is set at runtime?  I am able get a TStringGrid to recognize the dataset fields, but not other controls such as TEdit.</p>
  
  <p>Here are details of my project.  I have created a datamodule and a form. The datamodule which has the dataset objects and the form has a datasource along with UI controls.  To reduce dependencies between modules, I do not want the form unit to use the datamodule unit.  Rather, I want to set the datasource.dataset at runtime. If I use a TStringGrid, this strategy works, but with TEdit, it does not.  I have tried manually creating the fields in LiveBindings, but these do not map to the dataset.  If I were using VCL, this would be a non-issue, but I have been unable to figure out the best way to accomplish this with Livebindings. FYI, this is a FMX project. </p>
  
  <p>I also noticed that if I "used" the datamodule to create the Livebinding connections and subsequently unused it, the fields show up on the BindSourceDb and read (invalid).  When I run the application and set the dataset property at runtime, the TEdit controls are able to find the fields an will work fine.  Any suggestions how to do this without using and using modules?</p>
