Multi selection for a property filter combo box

Support
1

I have the following filtration implemented from a comboBox. Is it possible to make this filtration for multiple selections from a comboBox?

<propertyFilter id="licenseFilter" property="license.name" operation="EQUAL" dataLoader="organizationsDl" visible="false"/>
                <comboBox id="licenseCombo" allowCustomValue="false"/>

@ViewComponent
    private ComboBox<String> licenseCombo;
    @ViewComponent
    private PropertyFilter licenseFilter;

private List<String> getLicenses(){
        return dataManager.load(License.class).all().list().stream().map(License::getName).toList();
    }

@Subscribe("licenseCombo")
    public void onLicenseComboComponentValueChange(final AbstractField.ComponentValueChangeEvent<JmixComboBox, Object> event) {
        licenseFilter.setValue(event.getValue());
    }

@Subscribe
    protected void onInit(InitEvent event) {
        licenseCombo.setItems(getLicenses());
    }

Hi!

This is currently not possible, as there is no IN operator for the propertyFilter component.

Framework issue attached: Implement IN and DATE_INTERVAL operations in PropertyFilter · Issue #1442 · jmix-framework/jmix · GitHub

Also, you don’t have to manually bind the component to the propertyFilter, in your case.

The propertyFilter can use a custom component to input values automatically.
Just insert the tag of the desired component inside the propertyFilter.
E.g:

<propertyFilter id="licenseFilter" property="license.name" operation="EQUAL" dataLoader="organizationsDl" visible="false">
    <comboBox id="licenseCombo" allowCustomValue="false"/>
</propertyFilter>

In addition, the “MultiSelectComboBox” component is great for multiple selection of values. MultiSelectComboBox sample.

When the issue of implementing the “IN” operator will be solved, your code should be transformed as this:

<propertyFilter id="licenseFilter" property="license.name" operation="EQUAL" dataLoader="organizationsDl" visible="false">
    <multiSelectComboBox id="licenseMultiCombo" allowCustomValue="false"/>
</propertyFilter>

I hope my answer will be helpful for you.
