Exception when using a custom component from form builder

Hi All.

I am having trouble accessing custom components from within form builder in Orbeon-PE 4.2.

I have created a simple component from the tutorial:

<xbl:xbl xmlns:xh="http://www.w3.org/1999/xhtml"

xmlns:xf="http://www.w3.org/2002/xforms"

xmlns:xs="http://www.w3.org/2001/XMLSchema"

xmlns:ev="http://www.w3.org/2001/xml-events"

xmlns:xxf="http://orbeon.org/oxf/xml/xforms"

xmlns:fr="http://orbeon.org/oxf/xml/form-runner"

xmlns:xbl="http://www.w3.org/ns/xbl"

xmlns:xxbl="http://orbeon.org/oxf/xml/xbl">

<xbl:binding element="fr|abn" id="fr-abn-input" xxbl:mode="lhha binding value">

<xbl:template>

<xf:input ref="xxf:binding('fr-abn-input')"/>

</xbl:template>

</xbl:binding>

</xbl:xbl>

And then added it to the component list:

<property as="xs:string" name="oxf.fb.toolbox.group.typed.uri.*.*"

value="oxf:/forms/orbeon/builder/xbl/typed-controls.xbl

oxf:/xbl/orbeon/us-phone/us-phone.xbl

oxf:/xbl/sp/abn/abn.xbl

oxf:/xbl/orbeon/number/number.xbl

oxf:/xbl/orbeon/currency/currency.xbl

oxf:/xbl/orbeon/us-state/us-state.xbl"/>

The component comes up as available in the form builder - if I specify an icon for it, I can see the icon ok. I can drop it on to the form, but I can't see any fields in it, and as soon as I access it (click inside it) I get the following exception (full log attached):

|An Error has Occurred |

|----------------------------------------------------------------------------------------------------------------------|

|java.lang.NullPointerException |

|----------------------------------------------------------------------------------------------------------------------|

|Application Call Stack |

|----------------------------------------------------------------------------------------------------------------------|

|oxf:/ops/xforms/xforms-server.xpl | 43| 65|reading processor output |

|----------------------------------------------------------------------------------------------------------------------|

|Exception: java.lang.NullPointerException |

|----------------------------------------------------------------------------------------------------------------------|

I'm sure I'm missing something obvious here. Any help would be appreciated.

Thanks and regards,

Anthony

Hi Anthony,

Because your component is in the Form Runner namespace (http://orbeon.org/oxf/xml/form-runner), it needs to be in the xbl/orbeon directory; you can't put it in xbl/sp. And in case you wonder, the mapping from namespace to directory is done with a property, in this case:

<property as="xs:string" name="oxf.xforms.xbl.mapping.orbeon"
value="http://orbeon.org/oxf/xml/form-runner"/>

And of course, for the component to work in Form Builder, you need to have a metadata section for Form Builder. Here is the updated component:

<xbl:xbl xmlns:xh="http://www.w3.org/1999/xhtml"
xmlns:xf="http://www.w3.org/2002/xforms"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ev="http://www.w3.org/2001/xml-events"
xmlns:xxf="http://orbeon.org/oxf/xml/xforms"
xmlns:fr="http://orbeon.org/oxf/xml/form-runner"
xmlns:xbl="http://www.w3.org/ns/xbl"
xmlns:xxbl="http://orbeon.org/oxf/xml/xbl">

<xbl:binding element="fr|abn" id="fr-abn-input" xxbl:mode="lhha binding value">
<metadata xmlns="http://orbeon.org/oxf/xml/form-builder">
<display-name lang="en">ABN</display-name>
<description lang="en"/>
<icon lang="en">
<small-icon>/apps/fr/style/images/silk/money_dollar.png</small-icon>
<large-icon>/apps/fr/style/images/silk/money_dollar.png</large-icon>
</icon>
<template>
<fr:abn>
<xf:label ref="" />
<xf:hint ref="" />
<xf:help ref="" />
<xf:alert ref="" />
</fr:abn>
</template>
</metadata>
<xbl:template>

<xf:input ref="xxf:binding('fr-abn-input')"/>
</xbl:template>
</xbl:binding>
</xbl:xbl>

And this works fine, as far as I can tell.

Hi Alesandro.

Thank you for that. That was definitely the issue.

I have attached the component for reference - to be installed in the resources/xbl/sp/abn subdirectory. It's only a demo but may be useful for others.

Property to map the namespace to the class is:

Property to add the component to the form builder toolbox in the 'typed' group is:

<property as="xs:string" name="oxf.fb.toolbox.group.typed.uri.*.*"

value="oxf:/forms/orbeon/builder/xbl/typed-controls.xbl

oxf:/xbl/orbeon/us-phone/us-phone.xbl

oxf:/xbl/orbeon/number/number.xbl

oxf:/xbl/sp/abn/abn.xbl

oxf:/xbl/orbeon/currency/currency.xbl

oxf:/xbl/orbeon/us-state/us-state.xbl"/>

Thanks again and regards,

Anthony
