[Xsltforms-support] Problem with bind constraint

[Alexander H. <al...@ho...>]

Hi list,

I have a constraint problem.

I use this bind:

	<xf:bind id="bind_xxx" nodeset="instance('inst_xxx')/xxx" required="true()" constraint="string-length(.) > 1"/>

It works quite well in the following cases:

* If I have an input of string-length(.) = 1, <xf:alert/> labels show up, good.
* As soon as string-length(.) is greater than one, they go away, good.

Problem:

* If I have string-length(.) = 0, no <xf:alert/> labels show up, which is unexpected.

What is working as expected, is that I can not submit data (as it obviously does not fulfill the constraint).
But since no alert message is shown, I am not able to provide feedback about the missing value to the user.

Do you have any clue, what is happening here?

Thanks,
	Alex
