Hi Nick Van den Bleeken, Thanks for showing me the use of the constraint attribute! Works fine and I'll use it in many other cases too. One minor problem remains: would it be possible to delay the error msg / display until later (maybe submit)? Currently I simply have: /* Display a red background on all invalid form controls */ *:invalid {background-color:red;} Regards, Manfred Staudinger On 22/06/2009, Nick Van den Bleeken <Nick_Van_den_Bleeken@inventivegroup.com> wrote: > Hi Manfred Staudinger; > > You can add additional constraints to your instance data by using the > constraint[1] attribute on a bind (an invalid instance can't be submitted, > so this also solves your store problem). > > In your example: > <xf:bind nodeset="im:objektkategorie/im:vermarktungsart/@MIETE_PACHT" > type="xs:boolean" constraint="boolean-from-string(.) or > boolean-from-string(../@KAUF)" /> > > Makes the miete_pacht attribute valid if either miete_pacht or kauf is true. > To show a warning you can use the alert element on the input that binds to > miete_pacht attribute. > > In your example: > > <xf:input ref="im:objektkategorie/im:vermarktungsart/@KAUF"> > <xf:label>Verkauf: </xf:label> > <xf:alert>Either verkauf or Vermietung should be checked</xf:alert> > </xf:input> > > > Regards, > > Nick Van den Bleeken > R&D Manager > > Phone: +32 3 821 01 70 > Office Fax: +32 3 821 01 71 > Nick_Van_den_Bleeken@inventivegroup.com > http://www.inventivegroup.com > > 1: > http://www.w3.org/MarkUp/Forms/specs/XForms1.1/index-diff.html#model-prop-constraint > > >> -----Original Message----- >> From: www-forms-request@w3.org [mailto:www-forms-request@w3.org] On >> Behalf Of Manfred Staudinger >> Sent: zondag 21 juni 2009 22:10 >> To: www-forms@w3.org >> Subject: How to ensure that at least one of 2 attributes is set to true >> >> Hi List, >> >> I'm new to XForms, read a lot but still missing something: I did not >> find a solution (other than post-processing with xslt).
