CEGUI run-time error with setText()

[geminito]

Hello CEGUI folks. I'm so glad this project exists.

I have posted this problem on the OGRE Help forum, so I appologize if this is a case of "cross-posting". I don't think the OGRE forum was the best place for this question. Here goes.

I'm a bit stuck with a "Run-time error!" message while running my ogre+cegui app. I've got a CEGUI::MultiLineEditbox that I am popping up for users to enter text into.

Before popping up the editbox, I use setText() to initialize it with some text that the user can edit and save. Something like this:

mpEditorBox->setText( pszText );

For about 5 to 10 times, this works fine. But then a run-time error occurs, with a stack like this:

I have tried disabling Ogre's memory manager. I am also now using the mysterious CEGUI_fix.h header file instead of including CEGUI.h everywhere. This file is documented in the OGRE wiki. Not documented well, but it's there.

I am using the latest OGRE SDK. I'm not compiling OGRE or CEGUI myself. So, CEGUI is version 0.3.0 (I believe). The libraries included are:
OgreMain.lib CEGUIBase.lib OgreGUIRenderer.lib
These are from the usual D:\OgreSDK\lib location.

Any suggestions on how I should debug and resolve this problem? Clues? Thoughts? Anecdotes?

Cheers!
Neil

maybe a problem when the setText() fonction try to copy the text you provide to the text attribut of the EditBox.
Have you checked you'r "pszText" initialisation and lifetime ?

can't help more

I think you are seeing a bug that existed in the 0.3.0 release; the bug was fixed back in August. In order to rectify the issue you will need to update to a later version of the code, which means compiling CEGUI yourself, and possibly also re-compiling the Ogre CEGUI renderer module against the later CEGUI headers and libs.

If you want to stay with 0.3.0 and download the source package for that, you will need to do a cvs update (or checkout the v0-3 branch) to get the required fixes.

The 0.4.0 release source package contains this fix, so you might prefer that - especially due to all the new things added and other bugs fixed since 0.3.0. Though there have also been further bugs fixed since the 0.4.0 release, and a 'cvs update' is advised on this also (or just get the v0-4 branch).

A 0.4.1 release will likely be made sometime later this year.

It is currently strongly recommended that you do NOT use the cvs head version of the code

Thanks alot, CE!

I am currently compiling the latest stable OGRE code and will give CEGUI 0.4.0 a try. I read what is in 0.4.0, and definitely wanted to use it, so this was on my to-do list anyway.

Cheers!

FYI,

0.4.0 does fix the abend in setText described above.

Cheers!
