Bug 120215 BPS 40 - DE changes
1. all report elements' properties will be overidable with an expression. The binding expression will have access to report parameter, and static BIRT report objects only. 2) DE will provide api to get property binding expression for a given property on a report element handle. It's up to the engine to evaluate the property binding expression when the report gets executed. DE API changes -------------------------- a) DesignElementHandle will support the following two methods. - String (expression) GetPropertyBinding ( propertyName ) - void SetPropertyBinding( propertyName , String (expression) ) // Note get and set property methods are wrapper classes which actually use reportDesignHandle methods to retrive and set the property binding. b) rom.def changes Property bindings contains a list of binding expressions. ReportDesign element will be enhanced to support a new property called. <Property canInherit="false" detailType="propertyBinding" displayNameID="Element.Module.propertyBindings" isList="true" name="propertyBindings" type="structure"/> A new datatype - <Structure name="propertybinding"> <Member name="name" since="2.0" type="name"/> <Member name="id" returnType="any" since="2.0" type="string"/> // Use the unique id used to identify an element. <Member name="value" returnType="string" since="2.0" type="expression"/> </Structure>
