rev 46199 has visible property implemented with sample in showcase. Note that effect when the dialog closes (visible is false) still needs work.

ICEfaces4 trunk r46210:

1) showcase > dataTable > Scrolling testing found a styling issue when opening the table popup on this demo (all browsers), image attached. This was not an issue with IF4 trunk Jenkins Build 1588.

2) ace:dialog inside ace:tabSet:
A JS error is written to the console when changing from the tab displaying the dialog to any other tab.
Not an issue on the EE-3.3.0-maintenance branch r46213, or with ICEfaces4 trunk Jenkins build # 1572.

Steps:

• build dialog QA test app from: http://dev.icesoft.com/svn/repo/qa/trunk/Regression-Icefaces4/Sparkle/Nightly/dialog .
• on /dialogSparkleTabset.jsf, Tab1 is selected by default and the dialog is rendered; click on Tab2 or Tab3. The JS error is written to the browser console:

TypeError: ice.ace.DialogPanels[a] is undefined
http://localhost:8080/dialog/javax.faces.resource/dialog/dialog.c.js.jsf?ln=icefaces.ace&v=4_1_0_151112
Line 5

ICEfaces4 trunk r46222:
showcase > dialog > Effects and Size:
In Chrome/IE11, a browser console error occurred randomly when navigating away from the demo:

Steps: test this demo using a few effects, then navigate to another demo, such as Miscellaneous > DraggableDroppable > Overview.

Tested with ICEfaces 4 trunk r46245, ace:showcase ace:dialog > Effects and Size, Chrome FF, IE.
When opening the dialog box the first time or after submitting a change to the effects the dialog opens then closes then opens again. The dialog also opens in a location which is left of and lower than the center.
The open/close/open issue occurs no matter which effects are chosen but is especially easy to demonstrate if using "bounce" as the hide effect. Please see attached screen shots.
1.png - The first time opening a dialog it opens slightly, then closes, then opens again off center.
2.png - After closing the dialog then reopening, it renders centered. The open/close/open issue does not occur during the second or subsequent attempts to open the dialog UNLESS you change a show or hide effect or the size.

r46322: moved the call to the 'close' method, in the underlying widget, inside a conditional that checks if the dialog is visible; thus, if the dialog is already invisible we avoid calling the hide method and at the same time we avoid showing the hide effect

Tested with ICEfaces 4 trunk r46323. FF 34, Chrome 45, IE 11, 10, 9, 8. Issues as listed above are resolved. There is a new issue with the showcase ace:dialog > Overview demo. Using the "Click me once done with input" submits the value to the server but does not remove the modal dialog. Was not an issue in r46321

r46526: fix for setting the internal isVisible flag to true when executing the show() method in the client side, in order for the hide() method to work correctly

.hide() works again on my Emporium testing, thanks.

Verified ICEfaces 4 trunk r46533. FF 34, Chrome 46, IE 11, 10, 8.
