[Gambas-bugtracker] Bug #2787: Make WebPage.Render accept optional arguments

Sun Sep 24 19:03:35 CEST 2023

http://gambaswiki.org/bugtracker/edit?object=BUG.2787&from=L21haW4-

T. Lee DAVIDSON reported a new bug.

Summary
-------

Make WebPage.Render accept optional arguments

Type             : Request
Priority         : Low
Gambas version   : 3.18
Product          : Web components

Description
-----------

WebPage.class [https://gitlab.com/gambas/gambas/-/blob/master/comp/src/gb.web/.src/WebPage.class] has subroutines __Render() and _Render() both of which accept an Optional (_Arg) As Collection. Yet, Render() [@ line 55], which calls __Render(), does not.

I am unable to determine if this proposed change would even work or if it would cause any problem as my analysis of the code leads me to a dead-end. Render() calls __Render() which calls _Render() which, apparently, does nothing.

It might be quite handy to be able to pass values to a WebPage when it is rendered so public variables do not need to be used to share values between pages.
