Troubles with dynamically populating control structures
Locked
 
|
I am having difficulty populating a control structure directly from a query. My goal being to read from a user table and populate a select structure with the users that match the criteria set forth in the query. However, when I do this:
<xforms:select1 ref="users" id="user-select"> <xforms:label>Active Users </xforms:label> <xforms:item> <xforms:label>Choose One...</xforms:label> <xforms:value/> </xforms:item> <xforms:repeat nodeset="users" id="users-repeat"> <xforms:item> <xforms:label ref="name_concat"/> <xforms:value ref="user_id"/> </xforms:item> </xforms:repeat> </xforms:select1> only the first person the query returns shows up in the list. I have included a regular xforms:output into a table above to make sure my results are all coming through; which they are... So how to I take information from the query and populate my select structure properly? I have attached a tar of the relevant bits of my project, hopefully it will be a simple mistake on my part. dynamic-control-population.tar.gz |

Not sure if repeat within the select1 is supported by the spec - try itemset instead to see if that helps.

As per XForms, <xforms:repeat> is not supported within <xforms:select1>.
You are right, you must use <xforms:itemset nodeset="..."> instead. -Erik On May 29, 2008, at 5:45 PM, Alexander Zatko wrote: > Not sure if repeat within the select1 is supported by the spec - try > itemset instead to see if that helps. > > On May 29, 2008, at 4:44 PM, dcrensha wrote: > >> >> I am having difficulty populating a control structure directly from >> a query. >> My goal being to read from a user table and populate a select >> structure with >> the users that match the criteria set forth in the query.

(Pardon the email Erik, I hit the wrong reply button.)
With the repeat (even though it isn't supported) I get at least something from the users. When I use the xforms:itemset I don't see anything except the dummy Choose One entry manually defined in the select1 declaration. Is ther a special format in the nodeset string I have to use to reference my SQL call? To be specific: here's what I changed it to: <xforms:select1 ref="users" id="user-select"> <xforms:label>Active Users </xforms:label> <xforms:item> <xforms:label>Choose One...</xforms:label> <xforms:value></xforms:value> </xforms:item> <xforms:itemset nodeset="users" id="users-repeat"> <xforms:label ref="name_concat"/> <xforms:value ref="user_id"/> </xforms:itemset> </xforms:select1> Which I believed to, for every user in the query, put an item in the select1 control. Am I using the itemset tag the correct way here? |

I believe the itemset's nodeset attribute context is determined by the
@ref value of the select1 element, so your XForm's instance should contain the following structure if you expect the select1 to work as shown: <users> <users> <name_concat/> <name_concat/> .... </users> </users> If you don't make it work, send a test case that can be run in sandbox.

As suggested, the @ref attribute changes the XPath evaluation context
for @nodeset What does your instance data look like? Including: * Where are the items defined * Where do you want to store the selected value -Erik On May 29, 2008, at 8:30 PM, dcrensha wrote: > > (Pardon the email Erik, I hit the wrong reply button.) > > With the repeat (even though it isn't supported) I get at least > something > from the users.

Actually I figured it out. I was referencing the query directly, when the way I had it set up was to stuff the query into a dummy instance. When referenced that way, it worked fine.
ie. nodeset="instance('main')/users" Thanks for all your help guys. |
