Suppose you > have a form "ListParties" that you re-use all over and it needs two behaviors > for the "partyId" field: > 1. Normal behavior: Show the partyId as a hyperlink to the viewParty page. > 2. LookupParty behavior: In a LookupParty popup that uses ListParties, have > the partyId hyperlink do a javascript:set_value(partyId) instead. > This is a common scenario, where one has to re-use a field for different > purposes. The form widget supports this with the use-when attribute. One way > to set it up is to use the same field name="" and give them both use-whens as > follows, > <field name="partyId" header-link="sortLink" use-when="isLookup==false"> > <hyperlink description="${partyId}" > target="viewPartyLink?partyId=${partyId}"/> > </field> > <field name="partyId" use-when="isLookup==true"> > <hyperlink also-hidden="false" target-type="plain" description="${partyId}" > target="javascript:set_value('${partyId}')"/> > </field> > So in a lookup form, only the second one will be used. > The bug is that the header-link="sortLink" will not work. The sort link is > not rendered in the header, preventing the user from sorting by partyId. > However, if you swap the order of the field elements such that the > header-link one is second, it will work. > I traced this bug to ModelForm.java renderHeaderRow() where it decides how to > render the header-link. The current code marked "Modification Nicolas" is not > doing the right thing. It should be evaluating the use-when and comparing it > to any other one before deciding to continue. > For now the workaround is to make sure the header-link element comes after > the other one. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.undersunconsulting.com/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
