Added 'showListOnInput' property to component. Modified selectmenu.js to render drop down when 'showListOnInput=true' and key is pressed when component is in focus.

Verified ICEfaces4 trunk r43935. Tomcat 7, FF34 and Chrome 39.
When tabbing into the component in IE browsers, the first time focus is received via tab the list is presented. The second time tabbing through, the list is not presented until a key is pressed. This occurs in IE 8, 9, 10 and 11.

The 'showListOnInput' attribute test was added to the ace:selectMenu QA test application:
http://dev.icesoft.com/svn/repo/qa/trunk/Regression-Icefaces4/Sparkle/Nightly/selectMenu
Test page: //selectMenuDynAttribute.jsf

The list opens up when the 'showListOnInput' attribute is set to either true or false, and clicking/typing in the selectMenu.
When tabbing through, the list is not displayed when using 'showListOnInput' = true or false.
Tested with ICEfaces4 trunk r46164/ Chrome46, IE11, FF34.

Changed 'showListOnInput' behaviour to only show the list if the user types to edit the input field, not on focus or click. Reuse 'focus' event that initializes the component to also show the options when showListOnInput=false. When focus is gained due to a click on the component the 'click' callback is temporarily disabled to avoid having it hide the options back.

Tested with Chrome, Firefox, IE11 and IE9.

Okay, things seems a little messed up right now.

Using the showcase, without specifying 'showListOnInput=true', the list only displays once the user types into the input field. Clicking on the input field, or even the arrow, doesn't display the list.

What should be happening when 'showListOnInput=true" is:

• User clicks on input field - no list display.
• User clicks on arrow next to input field - list displays.
• User types into input field - list displays.

When "showListOnInput=false" / default:

• User clicks on input field - list displays.
• User clicks on arrow next to input field - list displays.
• User types in to input field - list displays.

Modified selectMenu client code to always respond to clicks on the down arrow regardless of 'showListOnInput' state.

Sorry Mircea, I've completely messed this one up!

Here's what we want:

No matter what showListOnInput is set to:

1. User clicks on input field with mouse - list displays.
2. User clicks on arrow next to input field - list displays/toggles.

This is all working except for #1.

What else should be happening when 'showListOnInput=true" / default:

User tabs into input field, types something - list displays. (Working)

When "showListOnInput=false":
#User tabs into input field types something - matching element (if one) is selected, no list displays.

1. User tabs into input field and then presses Space - list displays.

Also, I noticed right now that if you Shift-Tab out of the component the list displays and shouldn't.

Changed client code to follow the latest behaviour specs.
