jqxComboBox & jqxToolBar

[AsterionDBParticipant]

I have a jqxComboBox that is populated with JSON data using a jqxDataAdapter and an external source. I have noticed that when the jqxComboBox is part of a jqxToolBar, the data-adapter gets called 4 times – thus hitting my external source for the same data 4 consecutive times.

When the jqxComboBox is not part of a jqxToolBar, the data-adapter gets called once, as would be expected.

Is there a reason why the data-adapter is getting called 4 times?

Here’s my test-case. Thanks…>>>

import React from 'react'

import JqxToolBar from '../../components/jqwidgets-react/react_jqxtoolbar.js'

class TestCase extends React.Component
{
  comboBoxClosed(event)
  {
    console.log('combo box closed');
  }

  render() 
  {
    let fileTypeDS =
    {
      datatype: 'json',
      datafields: 
      [
          { name: 'FILE_TYPE', type: 'string' }
      ],
      id: 'FILE_TYPE',
      url: window.asterionRestAPI + '/getFileTypes'
    };

    let fileTypeDA = new window.$.jqx.dataAdapter(fileTypeDS);
    
    let tools = 'combobox';
    let initTools = (type, index, tool, menuToolIninitialization) => 
    { 
      switch (index)
      {
        case 0:  
          tool.jqxComboBox(
          { 
            width: 150, 
            source: fileTypeDA, 
            checkboxes: true, 
            displayMember: 'FILE_TYPE', 
            valueMember: 'FILE_TYPE'
          }).on('close', this.comboBoxClosed);
          break;

        default:
          break;
      }
      return { minimizable: false };
    }
    
    return (<JqxToolBar width={800} height={35} initTools={initTools} tools={tools}/>);
  }
}

export default TestCase

Hi AsterionDB,

A work item has been created. For now, place some flag to reduce the calls to one.
Sorry for the inconvenience.

Regards,
Ivo
