Ok, I agree with you. We have discussed this with conan today and get the same conclusion as you. We started looking at mosaic, but the biggest limitation we have right now is the GWT version we are using. New libraries are already using gwt 2.0, so we can´t use the latest versions of them. The same problem arise when composing widgets. GWT 1.5.3 is very basic.<br>

We will continue using native GWT or GWTExt until Guvnor is moved to GWT 2.x (I don´t know the effort required for that).<br><br>Best,<br><br><div class="gmail_quote">On Mon, Feb 1, 2010 at 11:31 PM, Michael Neale <span dir="ltr">&lt;<a href="mailto:michael.neale@gmail.com">michael.neale@gmail.com</a>&gt;</span> wrote:<br>

<div><br></div><div>I certainly think it is a very bad idea to use a framework like smart GWT now for widgets - the built in GWT ones are pretty basic, but it is worth the effort to compose them into richer ones, or look for GWT &quot;native&quot; ones to reuse - as at least they will be resolved at compile time. Some GWT ones to take a look at: <a href="http://vaadin.com/home" target="_blank">http://vaadin.com/home</a> and <a href="http://code.google.com/p/gwt-mosaic/" target="_blank">http://code.google.com/p/gwt-mosaic/</a></div>

Hi all,<div>Baunax and I are making some improvements in Guvnor&#39;s rule editor (from/collect/accumulate support, expression builder widget, etc.) and we want to start using Smart GWT (<a href="http://www.smartclient.com/" target="_blank">http://www.smartclient.com/</a>). This library is the successor of GWText (the one Guvnor is using now). You can see this in GWText home page <a href="http://code.google.com/p/gwt-ext/" target="_blank">http://code.google.com/p/gwt-ext/</a>.</div>




<div>Some of the reasons we have to move to Smart GWT are:</div><div><ul><li>GWTExt is deprecated. It is <span style="font-family: arial,sans-serif; font-size: 13px;">no longer under active development.</span></li>

<li><span style="font-family: arial,sans-serif; font-size: 13px;">Smart GWT is under LGPL license (just like GWTExt)</span></li><li><span style="font-family: arial,sans-serif; font-size: 13px;">Smart GWT support any version of GWT (from 1.5.3 to 2.0). There shouldn&#39;t be any problem when we start using GWT 2.xx</span></li>




<li><span style="font-family: arial,sans-serif; font-size: 13px;">Smart GWT has a lot of widgets, effects, layouts etc. that can make our life easier ;).</span></li></ul><div><font face="arial, sans-serif">Of course we are not going to migrate Guvnor to Smart GWT; we want just to use it for the new features we are implementing.</font></div>




<div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif">So, are you guys agree? Does anyone have any objection?  </font></div><div><font face="arial, sans-serif"><br>

</font></div><div><font face="arial, sans-serif">We are currently working on guvnor_expressionEditor3_baunax_esteban branch.</font></div><div><font face="arial, sans-serif"><br>
