Viewer 3.1 - Zoom issues

AshleyPeters — Thu, 31 Jan 2013 16:45:25 GMT

When the map first opens in the viewer, I have to click on the map before I can zoom. I can zoom as soon as the map opens in older editions in the viewer. Is there a setting I need to change somewhere to allow for a user to zoom without clicking on the map first?

Thanks in advance for your help!

Ashley,

That would involve adding this block to the index.mxml

    <fx:Script>
        <![CDATA[            
            protected function init():void
            {
                navigateToURL(new URLRequest("javascript: document.getElementById('index').focus();"), "_self");
            }
        ]]>
    </fx:Script>

Robert,

Thanks for the quick reply.

I tried adding that code into the index.mxml but it didn't resolve the issue.

Easiest way is to use Google Chrome, as this is the default 🙂

Just making that change did not do it for IE8, I also had to modify the <s:Application tag> as such:

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:viewer="com.esri.viewer.*"
               xmlns:managers="com.esri.viewer.managers.*"
               pageTitle="ArcGIS Viewer for Flex"
      creationComplete="init()">

Not sure if crationComplete is the right call to make there, but it is working.

Rhett,

Adding that line of code with the code Robert provided worked. Thanks!

Ashley,

Rhett is absolutely right I forgot to add that to my original post.

I just added the part that he forgot to. He would have got there once he realized it.

However, Robert is really the one that answered this question, and should get the check mark. Besides, I'm not in the running for MVP anyway, so would be a wasted check mark on me.

Robert,

the creationComplete="init()" works just fine, but I see that so does initialize="init()". (initialize "looks" more correct in this case)

At first wasn't sure what to use as normally I see creationComplete in like a widget or something that actually gets "created", but it worked.

However, curious if there is a "more correct" method, or does it not really matter how you call the init() function?

Rhett,

I have always used CreationComplete for this as I don't believe that it matters (in this case) if the javascript getts called before all the children of the index.mxml get created or after (which is where CreationComplete is called).
