GWT Designer lags on xml source autocomplete

Question

Some pretense: Using MyEclipse 8.6 with GWT 2.2.0. As you know it comes with GWT Designer now.

I've noticed that while editing the xml within GWT Designer, every time I type in a new attribute to a tag it starts to lag. The exact point is when I press '='. This lag freezes eclipse for about 1-2 minutes. As you can imagine, it makes using XML Source for UIBinder almost unbearable. I assume the lag is due to eclipse looking up suggestions to put into an auto complete drop down, but it takes a whopping 1-2 minutes.

My question is: How do you prevent eclipse from this type of lag while editing the XML source in GWT Designer? What are you developers doing to get around it?

Read here: https://groups.google.com/forum/#!topic/google-web-toolkit/2j0RulDMfgc/discussion.

You need to download the 2 xsd:

http://dl.google.com/gwt/dtd/com.google.gwt.user.client.ui.xsd
uibinder.xsd (replace com.google.gwt.user.client.ui.xsd in the url above. I can't post more than 2 urls yet...)

Then add them to the XmlCatalog (Window -> Preferences -> Xml -> XmlCatalog -> User Specified Entries -> Add.. -> FileSystem)

Worked for me.

Eclipse no longer freezes during auto complete. It still freezes if I try to format text by pressing ctrl+shift+F in the .ui.xml file.

Instead of using the WindowBuilder Editor, you can right-click on *.ui.xml file you're editing and select Open With -> UiBinder Template Editor. I am not using GWT Designer, and WindowBuilder doesn't have autocomplete for me at all, so I use UiBinder Template Editor instead.

It does the same thing with UiBinder Template Editor. It tries to suggest autocomplete. – Kenneth Mar 16 '11 at 17:02

I see a similar problem although I am using STS 2.6.0. I eventually worked around it by using the normal eclipse XML editor, right click Open With -> XML Editor but you lose autocomplete and some validation.

My first attempt was to add xhtml.ent, uibinder.xsd and com.google.gwt.user.client.ui.xsd to the XML Catalog as I suspected that it was something around blocking over the network getting these but that didn't help.

I also turned off all validation which also didn't have any effect.

So I wouldn't mind a definitive answer to this myself.
