Hi sylvain,<br>
<br>
This is not the case a renamed the variable so the have exactly the same name.<br>

On the other hand, may be the problem is that I am calling it from .js file by the next code:<br>

var appState;<br>

function getAppState() { return appState; }<br>

function newAppState(page)<br>
{<br>
appState = page;<br>
getAppState().k=1;<br>
getAppState().m=2;<br>
<br>
return appState;<br>
}<br>
<br>
// Funciones especificas<br>
<br>
function createBloomFilter() {<br>
console.log("Voy a llamar a generate filter")<br>
bloomfiltersdata.generateFilterInvokable2()<br>
console.log("Ya he llamado a generate filter")<br>

<br clear="none">
Two things:<br clear="none">
<br clear="none">
1. Call setContextProperty() right before before setSource(), so it's <br clear="none">
already available when the QML content is loaded.<br clear="none">
2. Use lowercase for context property names ("bloomfilters" instead of <br clear="none">
"Bloomfilters"). In some places, QML interprets IDs starting with an <br clear="none">
upper case letter as a type name, and that won't work then, therefore <br clear="none">
stick to lowercase.<br clear="none">
