It works very well, however I'm still unable to hide error messages on first display and then to display them after input error. I tried to make the same thing as in bizdoc example, but it doesn't work dynamicaly and only with fixed values "true" and "false", so I think that I'm missing something somewhere.
I use want to trigger error display only when the form have been send at least once, thus when the "action" value is different from empty string. With this code I don't get any error messages :-(.
And there are some things that i find a little weird, maybe because i'm not really familliar with xsl :
- when declaring xxforms namespace in this form, the "xxforms:valid" attribute for inputs is changed to "xxforms_1:valid", however it seems that it remains in the same namespace, does it comes from processor used to display xml ?
- at the end of my form, for debug purpose, I display current xforms instance, and except before first submission why
<xsl:copy-of select ="/*" />
<xsl:copy-of select ="document('oxf:instance')" />
do not return the same thing ? I get my valid item with its value from the first statement (thanks to xsl check), and xforms instance from the second.
