Compression exception

[mabello]

Great tool, thanks!
I have found some troubles while trying to compress this file.

Array.prototype.contains = function(element) {
    return this.indexOf(element) !== -1;
};

Ext.namespace("Ext.ux"); 

/** 
 * @class Ext.ux.DDView 
 * A DnD enabled version of Ext.View. 
 * @param {Element/String} container The Element in which to create the View. 
 * @param {String} tpl The template string used to create the markup for each element of the View 
 * @param {Object} config The configuration properties. These include all the config options of 
 * {@link Ext.View} plus some specific to this class.<br>

Any clue or I'm doing something wrong?

minifying or compressing?

Thanks jgarcia for your reply.
Minifying, I have a bounch of files and this one gives me troubles...

Thanks jgarcia for your reply.
Minifying, I have a bounch of files and this one gives me troubles...

This is the line that causes problems:

    classRe: /class=(['"])(.*)\1/, 

What I did was commented out that line and changed the following function (I replaced this.classRE with a local variable classRE) :

Ext.ux.DDView = function(config) {

    if (!config.itemSelector) {

        var tpl = config.tpl;
        var classRe = /class=(['"])(.*)\1/;
        if (classRe.test(tpl)) {

            config.tpl = tpl.replace(classRe, 'class=$1x-combo-list-item $2$1');

        }

        else {

            config.tpl = tpl.replace(this.tagRe, '$1 class="x-combo-list-item" $2');

        }

        config.itemSelector = ".x-combo-list-item";

    }

    Ext.ux.DDView.superclass.constructor.call(this, Ext.apply(config, { 

        border: false 

    })); 

};

Thanks for your kind reply, it works now.

Though, I have a problem creating the -debug.js file, JSBuilder stops working for no reason, it is stuck and I have to kill the process.

Hence, I have created my own tool to create the minyfied file and the debug file ( I use JSBuilder GUI to create the xml part I need).

Thanks a lot

[watrboy00]

I have noticed in my own experience for JS Builder to break on most regular expressions.

Would be nice to see if there is a possible fix for this.

For only the ext3 ext.jsb (ext2 ext.jsb is fine)
I'm getting this error with JS Builder 1.1.2.0:

Unhandled exception.....Name cannot begin with the '<' characer, hesacecimal value 0x3C. Line 2, position 2.

I don't see the problem, comparing this to the working ext2 jsb file.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
