   Hi,
   
   I m trying to upgrade my app using Sencha Cmd v 5.0.0.116 from version Ext JS 4.1 to Ext JS 5. I have used following commands to upgrade my app:
   
   

   
   

   Code:

   
   

   
   sencha  app upgrade <path-to-extjs5-sdk>
   
   sencha  app upgrade -ext
   

   
   Both commands failed with following error.
   
   

   
   

   Code:

   My workspace contains two parts which are run locally. One part acts as server(JBOSS) and other as a client(TOMCAT). Now ExtJS code is present in WebRoot folder in client side code,which contains jsp and js for client side UI.
   

   I pointed my cmd to above location, and tried to run both commands, but both failed with same error.

   
   

   I have also pointed my cmd to extjs folder where all extjs files are kept to be used by my web-app, but vain.
   
   

   
   

   Please help me out. I cant figure out where the error lies. Or what configuration should i tweak to make it upgrade.

Component autoEl iframe not saved

Using SA 3.0.4.1386, I am trying to create an autoEl-Component inside a Window.

Sometimes it is saved, sometimes it isn't

It saved correctly when I set autoEl to

{

tag:'iframe-'

}

but it did not save correctly when I set autoEl to

{

tag:'iframe',

url:'index.htm'

}

Instead, it was reverted to the previous value.

Then, when I change it to

{tag:"iframe"}

it is saved as

{tag:""}

Please help me to get it running!

CSS on TextButton not working properly

I'm working on a project which was made using GWT components but now I want to change to GXT components.

For some reason the CSS doesn't work properly on my GXT TextButtons.

Button:

TextButton test = new TextButton("Test");

test.setStyleName("testStyle");

Result

As you can see, the css is applied but only around the button. Have I missed something?

Column resize in Grid without headers

Hi

What I would like to achieve is to make all columns of a grid resizable, but having the grid header hidden.

Easy speaking all the column should have the border resizable, not just the header (that is not visible)

Any idea on how to do it?

ExtJs version 4.2.2

Thank
