3.9 RC 1 and XBL maps component

Hi,
I've been trying out the 3.9 RC 1 release with a reasonable amount of success until I've tried to use the XBL map component.

Has anybody used this OK?
Any ideas to help track this down gratefully received - see below for some diagnosis.

Thanks,
Ian

It's part of a long complex form but I've narrowed the problem down to the following:(i.e. if all of this is removed then the form loads)
                                    <div>
                                        <xforms:select1 ref="country">
                                            <xforms:label class="fixed-width">Country</xforms:label>
                                            <xforms:item>
                                                <xforms:label>please select</xforms:label>
                                                <xforms:value />
                                            </xforms:item>
                                            <xforms:itemset nodeset="instance('ins-country-items')/country">
                                                <xforms:label ref="label" />
                                                <xforms:value ref="value" />
                                            </xforms:itemset>
                                            <xforms:alert>Selecting a Country initialises the map
                                            </xforms:alert>
                                            <!--
                                                <xxforms:show ev:event="xforms-select" dialog="dia-map"/>
                                            -->
                                        </xforms:select1>
                                    </div>
                                   
                                    <div>
                                        <xforms:input ref="latitude">
                                            <xforms:label class="fixed-width">Latitude</xforms:label>
                                            <xforms:alert>
                                                <xforms:output
                                                    value="concat('Enter a coordinate value between -180  and 180 for the ', name(), ' field ')" />
                                            </xforms:alert>
                                        </xforms:input>
                                    </div>
                                    <div>
                                        <xforms:input ref="longitude">
                                            <xforms:label class="fixed-width">Longitude</xforms:label>
                                            <xforms:alert>
                                                <xforms:output
                                                    value="concat('Enter a coordinate value between -180 and 180 for the ', name(), ' field ')" />

                                        </xforms:input>
                                    </div>
                                    <div class="mapPicker">
                                        <p>

                                        <fr:map address-ref="lookupAddress" longitude-ref="longitude"

                                        </fr:map>
                                       
                                    </div>
What I'm seeing in the logs is a stack overflow:

Hi Ian,

Until a couple of weeks ago, xml-formatting.xsl was used by the XForms inspector, to show a nicely formatted version of the XML in the web page. Could you try turning off the XForms inspector, to see if you still get this error?

1.  If it is indeed due to the inspector, maybe by now you don't care about it anymore, since you most likely only use it during development.
2. But if you would like the inspector to run properly, you can upgrade to a nightly build, which doesn't use server-side XSLT for formatting.
3. Finally, if the issue isn't caused by the inspector, could you put this together in an single file XForms that we can run in the XForms sandbox to reproduce this?

Alex

Hi Alex,
Removing the inspector changed the error message but upgrading to the
release fixed it completely.

Thanks,
Ian

Ian,

Excellent, thank you for checking and confirming this one.
