Re: setFocus() in swf

Here's my standard HTML. Note the "onLoad()" in the body tag and the  
'id' param of the swfEmbed().
Not sure if this works in all browsers.

Problem with rtmpconnection (to red5) and 4.0.12

Hello,

I recently ran a lzx test app in 4.0.12 that makes a call to Red5.  What worked fine in an previous laszlo versions
has since stopped working.  This time, however, I am seeing the following compiler warnings:

extensions/av/rtmpconnection.lzx:14:49: Method rtmpconnection.call is overriding a superclass method of the same name which has been declared non-overridable
extensions/av/rtmpconnection.lzx:250:48: Method netremotecall.call is overriding a superclass method of the same name which has been declared non-overridable

Here is the example LZX:

<canvas debug="true">
    <button name="callButton" onclick="onCardEventCall();">
        Call sendEvent
        <method name="onCardEventCall">
            canvas.rtmp.onCardEvent.event = "button was clicked!";
            canvas.rtmp.onCardEvent.call();
        </method>
    </button>
    <rtmpconnection name="rtmp" debug="true" autoconnect="true" src="rtmpt://localhost:8888/srvr/myhome">
        <handler name="onconnect">
            Debug.write("connected");
        </handler>
        <handler name="onerror">
            Debug.write("error ",this.status);
        </handler>

       <netremotecall name="onCardEvent" funcname="onCardEvent">
            <attribute name="event" value="" type="string" />
            <netparam name="vars1"><method name="getValue">return parent.event;</method></netparam>
        </netremotecall>

       <netremotecall name="newEvent" funcname="newEvent">
            <method name="onResult" args="value">
                Debug.write('event received: ' + value);
            </method>
        </netremotecall>
    </rtmpconnection>
</canvas>

I see the rtmpconnection being made on the Red5 server, but when I try to send an event by clicking the "callButton"
it never comes through in Red5.  I'm thinking this has something to do with the compiler warnings.

Any thoughts?

<gridtext> to create an element?

Hello,

  In a databound grid, I want to use a <gridtext> for an "optional" node
in the dataset; ie. the gridtext datapath ("Description/text()") may not
match anything, and that's ok.  It works fine if there is a match, but
if there isn't for that row, I'd like to be able to create a node (the
Description) when text is entered.  Any clues how that can be done?

  Further info: in that case, when there's no matching node, trying to
enter text prints the error "setNodeText: p is null in Datapath ...".
I've tried doEnterDown() and various events to try to catch that and
create a node, but they don't "fire," I think due to that error.  I'm
using 4.0.11.

Re: Problem with rtmpconnection (to red5) and 4.0.12

I found out some further information.  I modified components/extensions/av/rtmpconnection.lzx to make the netconnection always through the line:

this._nc.call(func, obj);

instead of:

this._nc.call.apply(arguments);

This condition takes place at line 233 of rtmpconnect.lzx.  It seems like the compiler warnings say that the "call" method cannot be overriden in a base class.  So by reverting back to "this._nc.call(func, obj);" does the trick, but obviously this refactor was done for a reason.  Plus I still get the compiler warnings.

Hope this helps uncover some issues,
Tony

Re: Problem with rtmpconnection (to red5) and 4.0.12

Hmm, we rewrote how the base "schema" is declared to the compiler,and that does indeed declare "call" as a final method:

<interface name="Instance" extends="Object">
  <method name="validateClassStructure" final="true"/>
  <method name="initialize" />
  <method name="nextMethod" final="true"/>
  <method name="addProperty" final="true"/>
  <method name="constructor" final="true"/>
  <method name="hasOwnProperty" final="true"/>
  <method name="isPropertyEnumerable" final="true"/>
  <method name="isPrototypeOf" final="true"/>
  <method name="toLocaleString" final="true"/>
  <method name="prototype" final="true"/>
  <method name="apply" final="true"/>
  <method name="call" final="true"/>
</interface>

Since 'call' is a javascript built-in, it would really be best to rename this method in the library.

Re: <gridtext> to create an element?

Hi Jesse,

I guess the far most easiest way to achieve this, is to change your 
local gridtext-component (in "lps/components/lz/gridtext.lzx").
You only need to override the "updateData()"-method in the gridtext's 
editbox and handle in that place your node-creation code.
For instance like that:
>  <at>  <at>  -106,6 +106,15  <at>  <at> 
>                          this.globalMouseDel = new LzDelegate( this,
>                                                                
> "checkMouse" );
>                          super.init();
> +                    </method>
> +                    <method name="updateData" >

Re: Focusoverlay

Hi Greg,

I think you should be able to disable the focus overlay by saying:

<canvas>
     <attribute name="focusclass" value="null" />
     ...
</canvas>

problem on animator and LzTimer

Hi, everyone!
I set an animator to move a view horizontally. At the same time, a timer counts elapsed time.
The problem is, when the duration is larger than 45 sec, the animator stops 1sec before the timer get the right elapsed time.
That is, if the duration is 75 sec (my app need this value), the animator stops when the timer is 74 sec.

I list test codes below.
Why animator and LzTimer are not consistent? How to make them consistent?

Any idea is appreciated!

##### codes below  ############
<canvas debug="true">

    <attribute name="dur" type="number" value="$once{parseInt(canvas.setDur.getText())}" />

Unicode character is not showing in flash environment!

Hi,

I ran  the below code with the OL 4.0.11 server,

<?xml version="1.0" encoding="UTF-8" ?>
<canvas>

<dataset name="let" >
        <word>&#2949;</word>
</dataset>

 <simplelayout spacing="1" axis="x"> </simplelayout>
 <text datapath="let:/word/text()" fontsize="40"/>

</canvas>

---
I am getting the correct interpretation for the DHTML environment but
FLASH environment   is not showing the unicode character ( Its showing
only box like symbol...).

Thanks in advance!

Regards,
Ramesh G.
