This tag is used to iterate over n number of field list sets. Where the field lists sets are passed in multi-value request parameters. This tag could be called "For Each Multi-Value Field List Parameter". This tag would typically be used to process tempaltes where multiple sets of field lists are selected for including in the generated templates. For example, you can use this tag to process a template that has multiple field sections separated by a section header. Unlike regular templates where multiple field lists could be assigned to unique parameter names, these field lists are assigned to the same parameter name. Therefore, they are processed as multi-value request parameters. Additionally, each field list parameter value can have a number of other corresponding multi-value parameters. For example, each field list might have an associated Caption, a field type list, image name etc. As this tag iterates over the field set parameter values, it exposes current field set as a page scope attribute under the same name. Additionally, the other named corresponding multi-value parameter value are exposed on page scope attributes. The requirement is that the associated parameter names are in the same order in each set. If a field set parameter has the value equal to "all" or "required" then all data object attributes defined with the "Is layout by default" attribute set to true will be assigned to the field set. For example: http://localhost/JSPTemplates/MultiTest.jsp?selectedFields=name,account&selectedFields=address,state&selectedFieldsTypes=a,b&tselectedFieldsTypes=x,y&caption=First_Field_Set&caption=Second_Field_Set Passes in two field lists; named and corresponding field types and captions. For each iteration ( field set), this tag sets the current field set on the pageScope attribute named: selectedFields. The current caption is set on the pageScope attribute named: caption
