A Critical Bug in Gantt Chart 2.0

Uncaught TypeError: Cannot call method ‘getDate’ of undefined

This bug is even exhibited in your hosted demos.

If you delete whole tasks to start clean, and click on the + sign in the header, nothing will happen, except the javascript error shown above.

this is my sql table ddl:

CREATE TABLE gantt_tasks (

text varchar(255) NOT NULL,
start_date datetime NOT NULL,
duration int(11) NOT NULL,
progress float NOT NULL,

Can I post on this topic the bugs concerning dhtmlx_Gannt 2.0 ?
Is there another post to report the bugs ?
I use the version 2.0_130926 with php connector, mysql and IE 8.
I encountered some bugs concerning deleting links.
When I make a link and I delete it without reloading it works, it’s deleted.
When I reload the page and try to delete a link it disappears but it’s not deleted in the database. I reload the page and the link is still there.

#8

There is a problem with php connector ( only xml one is affected, json based one works correctly )

Please update gantt with the attached version, we will update the oficial version in few days as well.

Thanks for your reply.
I have tried the xml connector with your code but it doesn’t load the xml.
I have got this error : Error type: load XML / Description: incorrect XML
I have checked my config.php file and tried with 04_connector_json.html and it’s loading datas and updating correctly.
Thanks for your great work.

When I add a new task if it’s longer than the last date displayed, the chart is not updated.
When I reload the page with IE8, all the changes have made disappears. I have checked the mysql database and the datas are saved.
I have made a button to reinitialize like in the samples\01_initialization\14_reinitializtion.html but it doesn’t work. I call this function onclick:
function reinit(){
gantt.init(“gantt_here”);
}
Is it a problem with my navigator IE8 or with my configuration windows apache mysql or wth the library ?

#11

I have updated my library with the last dev package available. I checked with another post about the scroll bar.
My problem came from a

I have put on top of my chart.
I wanted something similar to this example dhtmlx.com/docs/products/dht … tures.html
I had to put this function :
function modSampleHeight(){
var headHeight = 122;
var sch = document.getElementById(“gantt_here”);
sch.style.height = (parseInt(document.body.offsetHeight)-headHeight)+“px”;
var contbox = document.getElementById(“contbox”);
contbox.style.width = (parseInt(document.body.offsetWidth)-300)+“px”;
gantt.setSizes();
}
I call it on load and it works just fine.
