Best Practice on Reusing forms

Question

Hi, 
 I would like to ask whats the best practice in using Reusable SAIL forms? 
 
 For example there are 3 forms. 
 Form1 - Contains Details (editable) 
 Form2 - Contains another details (editable) 
 Form3 - Holds both Form1 and Form2 (sort of a container) 
 
 Form1 and Form2 have Load() part and Form3 as well. 
 Is it okay to have Load() in each form? 
 I notice that the data in Form1 and 2 does not refresh until I reload browser the entire UI (Form3). 
 
 Is it a good practice to have Load on the Reusable UIs (Form1 and 2) ? 
 
 Thanks!

I haven't come across an explicit best practice that talks about how load() should be used for reusable UIs/nested interfaces but I've been a fan of keeping all my local variables on the main form (if possible). Within Form 1 and 2, they would be referenced as ri! inputs. This approach helps me keep track of code when I'm either developing or reviewing. Here's an example: 
 
----Main Form----- 
load( 
 local!variable1:123, 
 local!variable2:456, 
 local!variable3:789, 
 local!variable4:012, 
 
 a!formLayout( 
 firstColumnContents:{ 
 rule!form1( 
 variable1:local!variable1, 
 variable2:local!variable2 
 ), 
 
 rule!form2( 
 variable3:local!variable3, 
 variable4:local!variable4 
 ) 
 } 
 ) 
) 
 
----End of Main Form-----

---- Within Form 1----- inputs: ri!variable1, ri!variable2 
a!sectionLayout( 
 firstColumnContents:{ 
 a!textField( 
 value:ri!variable1 
 ), 
 a!paragraphField( 
 value:ri!variable2 
 ) 
 } 
) 
---End of Form 1 (The same would be for Form 2) ----- 
 
If the local variables aren't doing anything heavy (such as nested queries that retrieve several rows), then this approach is fine, otherwise, for performance, I would at least parse out "when" these local variables are declared/initialized within the main form & don't forget to use with() wherever needed (for refreshing data purposes).
