I have a question on how the local variables in a load expression behave when the expression is invoked from SAIL (which are at times TEMPO SAIL Dashboards).It took long time for analysis as the issue was causing several production issues. Let me try to explain the issue with some a SIMPLE SAIL and Expression Rules. Attached is a simple SAIL which has a one section layout. When you enter input "IndSection1" text box and change the date value in "End Date Field", "Tst_LoadIssueExpr" (code snippet is below) is invoked and result is shown in "ResultSet" text box.
When you change the flip the value in "IndSection1" between blanks and non-blanks, as expected the Boolean result displayed in "ResultSet" text box is not changing. But if you modify the below "Tst_LoadIssueExpr" ri!input directly rather than saving to a local variable ,the result shown is as expected.
Can anyone explain what is causing this weird behavior. In actual production code ,this is a n...

Nothing specific about sub-rules but I believe paragraph 3 of the notes section is describing your scenario particularly around context. I assume you have tried replacing load() with with() in your example to see that it works. Grids require a pagingInfo which has been defined in a load() but this should be defined in the parent SAIL rule and passed down to your sub-rule where your grid is defined.
