Description bugbridge 2007-02-06 18:52:22 UTC
Original status: 5-Cause Known; Suggested Status: NEW Original Target Release: mako_dev; Suggested Target Milestone : Dev Description: This was produced on update 7. This bug is been posted from the following forum thread. http://swforum.sun.com/jive/thread.jspa?messageID=203094 When I bind property ???rendered??? of a component to a bean???s property , the component disappears from visual page designer. This makes us hard to see where the component located on the page and very difficult to layout other components relative to the one with property ???rendered??? set. I suggest that these components should be visible at designing stage so we can lay out other components easily.. xxx@xxxx 2005-04-21 11:49:49 GMT Evaluation: This is because when the VB expression is evaluated, Insync creates a new instance of Boolean and returns the value. The default value is false, and so rendered gets set to false, which makes component become unrendered in the designer.

This issue needs to be fixed in insync by setting the default value of the Boolean to true.
Comment 2 _ sandipchitale 2007-07-17 03:31:05 UTC
Insync cannot set the default value of the Boolean property to true by itself. This should be handled by component's designtime renderer by showing a ghost component (maybe) when the rendered attribute's value evaluates to false (at design time).
Comment 3 Pegah Sarram 2007-07-17 21:14:33 UTC
After speaking with Sandip and looking at the issue in more detail, here is my evaluation. The rendered attribute means that the component should not be shown. In fact, setting that attribute via binding works as expected. The issue is that when the rendered attribute is set to false via the checkbox, the component doesn't disappear right away. This probably mislead the user to think that the incorrect behavior is with the property binding. The bug is in the designer where it doesn't update the component after its property is changed. If you refresh the page, or close and open the project, the component disappears. I'll file a new issue against the designer for that. However, to address the user's concern, we could render something like a dotted box around the components that have their rendered attribute set to false (or bound to a property). We need to come up with some kind of a visual effect for all the components that support the "rendered" attribute across the board. I will downgrade this issue to P3 and mark it as enhancement.
