METHOD AND SYSTEM FOR PROVIDING VALUE HELP FEATURES TO INPUT FIELDS GENERATED FOR DYNAMICALLY SELECTED COLUMNS

摘要

A method and system for providing value help features to input fields generated for dynamically selected columns is provided. A user interface element is generated for a dynamic key from the metadata. The user interface element has a name field and a value input field. A generic query having an attribute group is provided. The attribute group includes a name attribute, a code value attribute and an identifier value attribute. A sequence number is extracted from the metadata. It is determined from the sequence number that whether the user interface element is to be bound to the attribute group or not. A field type of the dynamic key is determined from the metadata. The name field is bound to the name attribute. The value input field is bound to the code value attribute if the field type is a code type. The value input field is bound to the identifier value attribute if the field type is an identifier type. Determining a query descriptor from the metadata. The query descriptor includes a first input parameter node and a first result node. The first input parameter node has a first attribute. The query descriptor is copied to a dummy query. The dummy query includes a second input parameter node and a second result node. The first input parameter node is identical to the second input parameter node and the first result node is identical to the second result node. The second input parameter node includes a second attribute identical to the first attribute. A screen is generated from the dummy query. The screen has a first input field bound to the second attribute and a result table bound to the second result node. A second input field is populated with a value of the second attribute from the second result node.
