Handling richtext in multifield - CQ5

Solution 1:

1) Overlay /libs/cq/ui/widgets/source/widgets/form/RichText.js 

2) In the overlaid file, at Line 910;  replace (a) by (b)

(a) this.el.dom.value = html;

(b) if(this.el.dom){this.el.dom.value = html;} 

Solution 2:

You need to set richtext's destroy event handler, to create dummy this.el.dom as shown below:

<myField

    jcr:primaryType="cq:Widget"

    name="./myField"

    xtype="multifield">

    <fieldConfig

        jcr:primaryType="cq:Widget"

        xtype="richtext">

        <listeners

            jcr:primaryType="nt:unstructured"

            destroy="function() {this.el.dom={};}"/>

    </fieldConfig>

</myField>
