[Progress Communities] [Progress OpenEdge ABL] Forum Post: Clarification on number of calls to BE's from JSDO

[christian.bryan@capita.co.uk]

Hi All We are using the JSDO in our application which is working okay but seems quite chatty and i want to make sure we are no making unnecessary requests to the back end. When we use it with our grids or our invokes we essentially do the following: Create a datasource - This makes an 'options' call to the Catalog and then a 'Get' call to the catalog Read the datasource - This makes a 'Get' call to the BE resource to get the data If its a KENDO GRID it also makes a count request which is again formed of an 'options' call and a 'PUT' So using this with a Grid, (on initial load) results in 5 calls or with an Invoke results in 3 calls. See example from a GRID Does this sound correct? Thanks Christian
