#28: Rename 'datagrid' widget to 'grid' ----------------------------------+----------------------------------------- Reporter: sakhmechet | Owner: sakhmechet Type: defect | Status: new Priority: low | Milestone: 0.1 Component: weblocks | Version: pre-0.1 Keywords: rename datagrid grid | ----------------------------------+----------------------------------------- There is no reason to call datagrid widget 'datagrid'. 'Grid' is a much better name. We should rename the widget. -- Ticket URL: <http://trac.common-lisp.net/cl-weblocks/ticket/28> cl-weblocks <http://common-lisp.net/project/cl-weblocks> cl-weblocks

#23: Create renderers for lists of items --------------------------------------------+------------------------------- Reporter: sakhmechet | Owner: sakhmechet Type: enhancement | Status: new Priority: medium | Milestone: 0.2 Component: weblocks | Version: pre-0.1 Keywords: renderers snippets lists items | --------------------------------------------+------------------------------- We should create renderers (or snippets?) to render lists of items (ordered, unordered, etc.) as this is a fairly common operation. We should consider rewriting current widgets that use lists to take advantage of this functionality. -- Ticket URL: <http://trac.common-lisp.net/cl-weblocks/ticket/23> cl-weblocks <http://common-lisp.net/project/cl-weblocks> cl-weblocks

[cl-weblocks-ticket] #44: ajax isearch will sometimes drop a callback in Firefox.

#44: ajax isearch will sometimes drop a callback in Firefox. -------------------------------+-------------------------------------------- Reporter: anonymous | Owner: sakhmechet Type: defect | Status: new Priority: critical | Milestone: Component: weblocks | Version: Keywords: prototype firefox | -------------------------------+-------------------------------------------- Sometimes, at least when a table is populated with more data than in the default example (try creating a table with 30 rows), an exception will be trown by Firefox because the "status" element in an nsIXMLHttpRequest is being accessed. How to reproduce: Add a longer list of employees to the grid1 in application.lisp: {{{ (list employee1 employee2 employee3 employee1 employee2 ...<30 more>) }}} Reduce the latency to 0.1 seconds in isearch.lisp, line 31. {{{ (with-javascript "~ new Form.Element.DelayedObserver('~A', 0.1, function(elem, value) {~ initiateFormAction('~A', $('~A'), '~A'); });" }}} Install firebug, and set a brakepoint at roughly line 1114 in prototype.js {{{ } catch (e) { 1114 this.dispatchException(e); <--- breakpoint on this line. 1115 } }}} After playing around with the isearch, you will see the following exception being thrown (really by the nearby success() function): {{{ [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: http://foo.org:8090/pub/scripts/prototype.js :: anonymous :: line 1109" data: no] columnNumber 0 data null filename "http://foo.org:8090/pub/scripts/prototype.js" inner null lineNumber 1109 location JS frame :: http://foo.org:8090/pub/scripts/prototype.js :: anonymous :: line 1109 language=2 languageName=JavaScript message "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]" name "NS_ERROR_NOT_AVAILABLE" result 2147746065 QueryInterface QueryInterface() initialize initialize() }}} From what I understand from random readings on the web, this can be caused by reading the nxIXMLHttpRequest.status in an onError handler (which does not seem to happen in this case), or it can happen if the ajax request is being aborted. -- Ticket URL: <http://trac.common-lisp.net/cl-weblocks/ticket/44> cl-weblocks <http://common-lisp.net/project/cl-weblocks> cl-weblocks
