JavaScript exception "Object doesn't support property or method 'blockOnFieldBusy'"

[agalataud]

Hi

We're using SmartGWT 4.1p (2014-07-08 nightly build).
Under conditions we were not able to determine, an exception is thrown when a FormItem gains focus (user clik, tab, ...) in a form.
Almost all our forms suffer this bug, but not all. Trying with a simple unit test didn't help (not reproduced).

This happens only in IE (Chrome and FF ok).
What could cause such problem?

Any help appreciated. Thanks in advance

Hi agalataud,

I had similar problems with the build from end July (24th-25th(?)). I don't know the exact trace anymore, but it was related to ComboBoxItems and perhaps SelectItems.
They went away with a newer build (perhaps 4.1-p20140727). Did you already try an August build?

Best regards,
Blama

I've just tried with the latest nightly (2014-08-03) and the problem is still there.

With this version I face a 2nd possible regression with ListGridField.getCanHide:

java.lang.IllegalArgumentException: Something other than a Java object was returned from JSNI method '@com.smartgwt.client.core.DataClass::getAttributeAsBoolean(Ljava/lang/String;)': JS value of type boolean, expected java.lang.Object

The second problem you mention is a dev-mode only problem which we'll address in the next build. We don't believe it's related to your original issue.

[Isomorphic]

The IllegalArgumentException should be fixed in today's build of SGWT 5.0d and 4.1p.

[agalataud]

Thanks for the update.
Any idea on what could cause the first problem?

[Isomorphic]

No one else has reported this, so you'll need to provide a way for us to reproduce it. If you can create a standalone repro case or tell us how to modify a showcase sample to hit the problem, that would help.

[agalataud]

It turns out it was a mistake on our side.
Thanks for your help.
