[mart-dev] Multiple main tables configuration issues

[allank]

Hi all,
I am unable to query from a biomart schema having two tables and (at the 
moment) one dimension table, I get a " SQL FAILED - LIKELY XML 
MISCONFIGURATION ERROR ..." error at the result display stage on the 
biomart web application.
I have setup the biomart table structure in accordance with the multiple 
main table requirements, in Martj I "validate all" and I get no errors, 
when using the web application, I am able to go smoothly through the 
filter process and the field-section-for-output stages the pane at the 
right indicates I have 32 entries at the output level, when I attempt to 
proceed to the output display page, I get the message " SQL FAILED - 
LIKELY XML MISCONFIGURATION ERRORUnknown column 'main.timepoint_id_key' 
in 'where clause'".
Could the error have been caused from using a key field (in my case 
timepoint_id_key) for fields from the dimension table that is not found 
in all the main tables. If this is so, how can I manage the situation 
where I have a main table (dataset__A__main) having a one to many 
relationship with one dimension table (dataset__C__dm) and other main 
table (dataset__B__main) which will have one to many relationship with 
several dimension tables.

Allan.
