Unexpected error - TypeError: 'null' is not an object

[lorezyra]

Designer version tested:

Designer 1.2.2 rev 28

Operating System:

WinXP Pro

Framework:

Ext JS 4.x

Description:

I'm migrating my app from EXTjs3 to EXTjs4 by rebuilding the entire app in Designer.
Made changes to a container's properties while in code-view mode
Switched to Design view and XDS crashes!
(Am I missing something in TPL configs?)

Steps to reproduce the problem:

create a simple ArrayStore
add 1 integer field with the name "id"
add 1 string field with the name "username"
add 1 string field with the name "fullName"
add 1 string field with the name "email"
add 1 string field with the name "name"
add 1 Boolean field with the name "enabled"
add 1 Boolean field with the name "banned"
add 1 integer field with the name "offenseCnt"
add 1 date field with the name "joinDate"
Create a window with a basic container
add a combobox
change to code-view mode
Config the renderTpl property (eg: '<tpl for="."><div ext:qtip="{fullName}<BR>email:{email}<BR><BR>enabled:{enabled}<BR>banned:{banned}<BR>Offenses:{offenseCnt}<BR>JoinDate:{joinDate}<BR>Group:{name}" class="x-combo-list-item">[{id}] {username}</div></tpl>')

The result that was expected:

should render the window with combo-box without issue.

The result that occurs instead:

Crash with TypeError

Debugging already done:

Found that the renderTpl config caused a strange null error.
Deleted the renderTPL property, and everything started working.

Possible fix:

lorezyra -

The renderTpl is a really low level component configuration to be used in conjunction with renderData and renderSelectors. We'll look at improving this experience for the end developers.

I think you are probably looking for the tpl configuration.

@aconran:
You are correct... Except that property is not available! "tpl" is needed for my comboboxes. When I type "tpl" in the filter box for the property grid, it only displayed "activeErrorsTpl" and "renderTpl!" I suspect this is another bug in Designer (1.2.2.r48)

Here's the screenshot of what I see and why I tried to use the renderTpl property... "tpl" is actually what I wanted...


(this is a ExtJS 4.x project)


XDS 1.2.2-27 BUG - no tpl on ComboBox.jpg


Okay, I'll file a different bug report for this one...

I've created a new bug report for the TPL issue: http://www.sencha.com/forum/showthre...y-for-ComboBox
