The thing is, these are about 20 properties that have to be calculated per entity and then displayed. I thought it would be handier to use something I already had, and is known not to have errors, instead of creating extra calculation methods with the risk of extra errors, as every extra line of code creatse more errros. I suppose I should be looking at your WOWODC2010 presentations, but unfortunately these are still not available... > Ramsey > > On Dec 16, 2010, at 3:04 PM, Johan Henselmans wrote: > >> >> Here's the idea: >> >> I have a custom component page from somewhere else with javascript that does >> a whole bunch of calculations based on values of an EO. >> >> No problem, I thought, according to the D2W Rules References I follow rule 7: >> >> (http://wiki.objectstyle.org/confluence/display/WO/D2W+Rules+Reference+-+Cookbook+-+FAQ) >> >> 7.
