Visjs / GWT

[Philippe Pithon]

Hello,

I know that there is not wrapper gwt for visjs.org but I tried to integrate with JSNI

And I have this error :

Caused by: com.google.gwt.core.client.JavaScriptException: (TypeError) @test.test.client.moduletest::initWave()([]): me._toScreen is undefined at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:249) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:136) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:571) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeVoid(ModuleSpace.java:299) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeVoid(JavaScriptHost.java:107) at test.test.client.moduletest.initWave(moduletest.java) at test.test.client.moduletest.onModuleLoad(moduletest.java:167) ... 9 more

ideas ???

In gwt.xml I add :

<script  src="vis/vis.js"></script>

and copy vis in public directory

Code in GWT :

public native void initWave()/*-{

    var container = $doc.getElementById('toto');

   

    var data = [

    {id: 1, content: 'item 1', start: '2013-04-20'},

    {id: 2, content: 'item 2', start: '2013-04-14'},

    {id: 3, content: 'item 3', start: '2013-04-18'},

    {id: 4, content: 'item 4', start: '2013-04-16', end: '2013-04-19'},

    {id: 5, content: 'item 5', start: '2013-04-25'},

    {id: 6, content: 'item 6', start: '2013-04-27'}

  ];

  var options = {};

  $wnd.vis.Timeline(container, data, options);

   

   

}-*/;

You have to create a Timeline with the new keyword, like:

new $wnd.vis.Timeline(container, data, options);

Now, I have this error with insert "new" :

(Error) @test.test.client.moduletest::initWave()([]): Unknown dataType 

my code :

public native void initWave()/*-{

    var container = $doc.getElementById('toto');

   

    var data = [

    {id: 1, content: 'item 1', start: '2013-04-20'},

    {id: 2, content: 'item 2', start: '2013-04-14'},

    {id: 3, content: 'item 3', start: '2013-04-18'},

    {id: 4, content: 'item 4', start: '2013-04-16', end: '2013-04-19'},

    {id: 5, content: 'item 5', start: '2013-04-25'},

    {id: 6, content: 'item 6', start: '2013-04-27'}

  ];

  var options = {};

  new $wnd.vis.Timeline(container, data, options);

   

   

}-*/;

[Philippe Pithon]

If I remove data (arg null), the timeline is display ! (but with no data...)

new $wnd.vis.Timeline(container, null, options);

Ideas ?

[Jos de Jong]

Ehhh, that sounds logic: if you don't provide data, the Timeline will display no data.

For future discussions related to vis.js, could you please use the github issues section of vis.js? https://github.com/almende/vis/issues

[Philippe Pithon]

Yes, but when I put data, I have this error : 

ok for next time :  https://github.com/almende/vis/issues

[Jos de Jong]

Are you using vis.js 2.0.0? There was a fix there with correctly recognizing Array input. If I remember correctly, GWT does some non-regular things with native Arrays, that may cause this issue.

[Philippe Pithon]

it works with 2.0.0 !!!!

thank you very much for your quick responses!

Philippe.

ok great
