Hi, Artyom,

This might be a good question for the XSLTForms e-mail support list (copied
here). From what I can tell, since your subform target is in a separate
<xf:case>, it is not possible to load the subforms a second time without
toggling the case again. If I add <xforms:toggle case="form-sub"/> to the
#form-main triggers, it seems to work as expected:

<xforms:trigger>
    <xforms:label>Open subform 1</xforms:label>
    <xforms:action ev:event="DOMActivate">
        <xforms:message>Opening subform 1</xforms:message>
        <xforms:toggle case="form-sub"/>
        <xforms:load show="embed" targetid="subform"
resource="showform3_subform1.xml"/>
    </xforms:action>
</xforms:trigger>
