How to make setup_wizard.xml <bindtofield>for [installedpackages]?</bindtofield>

davidiau

Hi, I've been trying to write a custom setup_wizard.xml, and I need it to update fields for an installed package, but it doesn't work as expected.
For instance, if I have a package named 'test' with a variable/field named 'timerdelay', by default it's config is stored to <installedpackages><test><config><timerdelay>value</timerdelay>

In setup_wizard.xml, if i use


 <field><name>timerdelay</name>
<description>Timer Delay (seconds)</description>
<type>input</type>
<bindtofield>installedpackages->test->config->timerdelay</bindtofield></field>

& then run thru the wizard and put '0' in the timerdelay input box it writes the value to
<installedpackages><test><config>0</config>
not
<installedpackages><test><config><timerdelay>0</timerdelay>
as I expect it to.

I tried also using

 <field><arraynum>0</arraynum>
<unsetfield>yes</unsetfield>
<name>timerdelay</name>
<description>Timer Delay (seconds)</description>
<type>input</type>
<bindtofield>installedpackages->test->config->timerdelay</bindtofield></field>

but that produces errors in wizard.php and writes an empty config.xml and I have to use backup to restore a working config.
does anyone know how to make this work?

Thanks,
David I</config></test></installedpackages></test></installedpackages></config></test></installedpackages>
