<p>For rl 1, you might want to look at the links Neil provided in
his answer:<br>

<p>Robotlegs 2 offers more solutions to this kind of problems than
Robotlegs 1.</p>
<p>See: <a href=
"https://github.com/robotlegs/robotlegs-framework/tree/master/src/robotlegs/bender/extensions/viewProcessorMap">
https://github.com/robotlegs/robotlegs-framework/tree/master/src/ro...</a></p>
<p>and the readme file for inspiration:<br>
<a href=

https://github.com/robotlegs/robotlegs-framework/blob/master/src/ro...</a></p>
<p>One of the many ways of using the ViewProcessorMapExtension:</p>
<p>For example, you could inject a class containing some config
values (rectWidth, rectHeight) into the View.</p>
<p>In your context config class:</p>
<p>injector.map(SomeVO).asSingleton();</p>
<p>_viewProcessorMap.map(ViewToBeInjected).toInjection();</p>
<p>In ViewToBeInjected:<br>
[Inject] public var someVO:SomeVO;<br>
…<br>
graphics.drawRect(0, 0, someVO.rectWidth, someVO.rectHeight);</p>
<p>or</p>
<p>in your context config:<br>
const expectedViewWidth:Number = 100;<br>
const expectedViewHeight:Number = 200;</p>
<p>injector.map(Number,
'rectHeight').toValue(expectedViewHeight);<br>
injector.map(Number, 'rectWidth').toValue(expectedViewWidth);</p>
<p>_viewProcessorMap.map(ViewToBeInjected).toInjection();</p>
<p>In the View:</p>
<p>[Inject(name="rectWidth")] public var rectWidth:Number;</p>
<p>[Inject(name="rectHeight")] public var rectHeight:Number;</p>
<p>…</p>
<p>graphics.drawRect(0, 0, rectWidth, rectHeight);</p>
<p>Does this help?</p>

<p>Thank you for the links. I am already using the Presentation
Model pattern, because I dislike the chaotic nature of global
events. I prefer to work against well-defined interfaces, which are
just as good for separation of concerns, but much better for
compile time safety, coding (IDE support), and testing.</p>
<p>If I understand your suggestion correctly, using the View
Processors follows pretty much the same life cycle as I described
in the first paragraph of my original post, only without additional
events and with no boilerplate code. That sounds pretty useful. I
am not sure if I can use that at the moment, because I am using
Starling for my project, with s9tpepper's plugin for RL, which may
only work with RL-1.</p>
<p>Is the target release date for RL-2 known?</p></div>inquisitortag:robotlegs.tenderapp.com,2009-10-18:Comment/240398362013-01-22T09:59:21Z2013-01-22T09:59:21ZHow do I initialize a view without a model?<div><p>Hey inquisitor,</p>
<p>Yes, ViewProcessorMap is pretty flexible. Take a look at the
very simple example I posted yesterday in another post:</p>

<p>Oh, that’s a hard to answer question! ;-)</p>
<p>Here, Shaun’s answer on Twitter:<br>
“It'll be released when it's been thoroughly reviewed:
<a href=
"https://github.com/robotlegs/robotlegs-framework/issues/99%E2%80%9D">
https://github.com/robotlegs/robotlegs-framework/issues/99”</a></p>
<p>In fact, everyone who’s trying out RL2 and is writing
about encountered rl2 issues/problems on this forum is also
contributing to that reviewing process! Thus, I encourage you to
start using RL2 :)</p>
<p>Cheers,<br>

(however <a href=

<p>Hehe, I agree, SARS is a disturbing acronym. I don’t know
whether Vjekoslav was intentionally trying to scare us, but since
only Robotlungs would be affected by an infection, we
shouldn’t care: P</p>
<p>Have fun with Robotlegs 2 and Starling!</p></div>Ondina D.F.
