How to renew stores with each different data, thus refreshing tree. #49

Closed ClementYap closed 10 years ago

ClementYap commented 10 years ago

I am still looking for solutions or tips how to renew store with different set of data so that the tree is refreshed. Please advise. I am thinking of ..liken event or observable. like this as shown below but it does not work.

function refreshStore(givenBatch) { try { if (givenBatch.msg) { registry.byId("corner3").model.clearCache(); registry.byId("corner3").model.store.setData(givenBatch.msg); registry.byId("corner3").body.refresh(); } } catch (e) { alert("Error: When refreshing tree, " + e); } };

regards Clement

First, there is not method model.clearCache(). Second, the method store.setData() is not observable. To refresh a cbtree you must use one of the cbtree stores and then reload the store, please see Reload Store

Hi, the first time it works. There are 2 buttons that each got data from mysql database by means of dojo.request. Both of the are working. I also have enabled property "clearOnClose". Whenever, the store is initialized, I am able to use both button to load the store for the first time. But in the second time, I again tried any button, the store is not loaded again.

Please see my function code:- function refreshStore(givenDB, givenCard, givenBatch) { request.post('list_tree.php', { data:{nameDB : givenDB, nameCard : givenCard, selectedBatch : givenBatch}, handleAs: "json" // JSON.parse is auto so JSON.parse is not needed ahead. }).then (function(response) { try { if(response.msg) { console.table(response.msg); console.debug("Loading into the store now!!"); storeA.close(); storeA.load({data:(response.msg), getChildren: function(object) { return this.query({parent: object.id}); } }); } } catch(e) { console.debug("Error: When refreshing tree, "+e); } }) }

The error prompted is "Error: When refreshing tree, TypeError: this.onLoadDeferred is undefined".
