I have encountered a glitch in Orbeon 2017.1 that did not occur in late 2015/early 2016 versions of the software: an error popup which has occurred when adding certain elements into the xforms:instance
Exception in client-side code.
Message: l is undefined
File: http://localhost:8080/orbeon/xforms-server/orbeon-266479e766510e28f420e559b3a49c43f8b18400.js
Line number: 79
After a few hours of testing, I have narrowed it down to the following. When an xxforms:dialog appears within a repeated node (xforms:repeat), and new elements are added, the error occurs. Note that the error does not occur if the the element already exists by xforms-ready. To summarize my problem, I have a generic XBL component that will display an xxforms:dialog of attributes that can be edited, as derived dynamically by reading an XSD. This dialog can appear many places within an XForms application, for virtually any element. If the element in which the XBL is not repeatable (but added by DOMActivate), there is no error. Only in xforms:repeat.

Here is the XBL:
<xbl:xbl xmlns="http://www.w3.org/1999/xhtml" xmlns:xforms="http://www.w3.org/2002/xforms" xmlns:ev="http://www.w3.org/2001/xml-events"
xmlns:xxf="http://orbeon.org/oxf/xml/xforms" xmlns:xbl="http://www.w3.org/ns/xbl" xmlns:xxbl="http://orbeon.org/oxf/xml/xbl"
xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fr="http://orbeon.org/oxf/xml/form-runner" xmlns:my="http://null">
<xbl:binding id="my-dialog" element="my|dialog">
<xbl:template>
<xforms:group xbl:attr="model context ref bind" xxbl:scope="outer">
<xbl:content includes="xforms|label,xforms|help,xforms|hint,xforms|alert"/>
<xforms:group xxbl:scope="inner">
<xforms:var name="binding" as="node()?">
<xxf:sequence select="." xxbl:scope="outer"/>
</xforms:var>
<div>
Iside the XBL:
<xforms:trigger appearance="minimal">
<xforms:label>Click for dialog</xforms:label>
<xforms:action ev:event="DOMActivate">
<xxf:show dialog="element-attributes"/>
</xforms:action>
</xforms:trigger>
</div>
<xxf:dialog id="element-attributes" appearance="full" level="modal" close="true" draggable="true" visible="false">
<xforms:label>Dialog</xforms:label>
<div>Here's the dialog text</div>
</xxf:dialog>
</xforms:group>
</xforms:group>
</xbl:template>
</xbl:binding>
</xbl:xbl>
This form will load without errors. You can click the "Click for dialog" trigger in the XBL portion to show the xxforms:dialog because element1 is already in the model. However, if you click the trigger to add another element1, there will be an error dialog in client-side code. If you click the trigger to add element2, there's no error because element2 is not repeatable. You can therefore click the "Click for dialog" within element2 and the xxforms:dialog will appear.
Is there a workaround for this, or is this a bug in the current version of Orbeon? It did work in the version I ran earlier in 2017.
