Bug 136402 Data binding feature - Expression builder bug
In the following 2 scenarios the expression builder does not behave as expected. 1) Invoked from data binding tab - Create a table report item, bind it to a dataset. - Go to the binding tab - Add a new data binding column - Invoke the expression builder to enter the expression. Current behavior - The expresssion builder does not show Available Datasets and Available Binding Columns Expected behaivor - The expression builder list the Available Datasets and Available Binding Columns 2) Invoke expression builder from Group dialog - Add a group to the above scenario - Go to binding tab on group dialog - Click on add to add a column binding - Invoke the expression builder Current behavior - Does not show Available Datasets and Available Binding Columns Expected behavior - Shows Available Datasets and Available Binding Columns
