Module property and deferred binding not evaluated correctly after recompile in super dev mode (SDM)

[Robert Hoffmann]

I am using super dev mode (SDM) with GWT 2.7.0.

I use the following module code to create a new property (user.agent.ie8) based on the user.agent property:

>>

    <!-- !!! define a pure ie8 variable (no fallback from ie9) -->

    <define-property name="user.agent.ie8" values="true,false"/>

    <set-property name="user.agent.ie8" value="false"/>

    <set-property name="user.agent.ie8" value="true">

        <any>

            <when-property-is name="user.agent" value="ie8" />

        </any>

    </set-property>

<<

Testing this from IE8:

When I clean and compile the entire module the following deferred binding (based on the new property) works:

>>

    <replace-with class="com.example.SelectionFactoryImplIElt9">

        <when-type-is class="com.example.SelectionFactory"/>

        <any>

            <when-property-is name="user.agent" value="ie6" />

            <when-property-is name="user.agent.ie8" value="true" />

        </any>

    </replace-with>

<<

However, when I then start SDM and recompile. The above deferred binding fails (SelectionFactory is not replaced with the IE8 version). 

In both situations I made sure that user.agent is indeed ie8. Also the SDM log states "binding: user.agent=ie8".

I would be thankful for your input. 

Best regards, Robert

Please try GWT 2.8-SNAPSHOT. 

If I remember correctly there were some commits regarding permutation properties and SDM recompiles after 2.7 has been released.

Yes. GWT 2.8.0-SNAPSHOT fixes this problem!

However under 2.7.0 I was using com.google.gwt.dev.codeserver.CodeServer with the -src attribute. Is there a way to include external source paths with the new SDM ?

Thank you

What do you mean by "new SDM"? Isn't it basically the same between 2.7 and 2.8? (I don't remember seeing any major change land in the codebase)

In other words, CodeServer with -src should work just as well; just remember to also use -launcherDir (as in 2.7 BTW).

There's no equivalent to -src with DevMode though, everything has to be put in the classpath.

This is the output I get when launching SDM from IntelliJ IDEA (14):

To add to the confusion, the documentation at http://www.gwtproject.org/articles/superdevmode.html mentions for exmple the allowMissingSrc attribute which is not listed above either.

Thank you,
Robert

DevMode vs. CodeServer.

Ok. Just for the record. 

The GWT plugin that comes with IntelliJ 14 does not use CodeServer. It does have a "Super Dev Mode" option, but then does not allow any extra parameters like launchDir or src. http://stackoverflow.com/a/27571401/1417396

Most importantly however the deferred binding bug described in this topic, is solved in GWT 2.8.0-SNAPSHOT.
