Hi all,

 Has anyone encountered an issue with the metadata XML box? We’ve installed i2b2 1.7.12a, and our ontology works fine. However, when we try to load concepts with C_METADATAXML populated (for enumerated choices) we keep getting this error:

This error doesn’t show up on the older versions of i2b2 with the same XML data, so we’re not sure why it’s returning this. The logs (console and wildfly server) show no further detail, so I’m kind of at a loss on how to debug this further.


We’d appreciate any help we can get.

Clearly, I should have tested to make sure the screenshot goes through. Here is the screenshot

The error message is "A problem was encounter while loading the html for the value type!".

We are also experiencing the same issue after a somewhat recent update to this version that was not previously present. Here is the error message on some lab values that only appears to happen in certain browsers (Safari and any chromium-browser):

Any help on this would be much appreciated if you've experienced a similar issue as it ruins a lot of functionality for our users.

This has been reported by one other user but I cannot replicate it. Perhaps you can give more information?

Also, you might try this commit that fixes a problem with HTTP/2 for lab values: https://github.com/i2b2/i2b2-webclient/pull/12/commits/93a46d5bfcd8a93444a7e7478597317e17a13217 ... But I am not sure why it would only happen on some browsers...

Hi Jerrod,

I was the one who reported the issue.  I assumed that the fix was pushed to the code base, but in case it wasn't, I have denoted it below.

Nich Wattansin was the one who suggested this fix, and it seems to have worked:

For now, there are two paths you can take to fix this:


  1. The issue is fixed in the current Github repository. You can go to https://github.com/i2b2/i2b2-webclient/tree/master/js-i2b2/cells/CRC/ModLabValues and download & replace 7 javascript files in your web client. They are all named CRC_view_{TYPE}.js, such as CRC_view_ENUM.js. The files are:
  1. CRC_view_ENUM.js
  2. CRC_view_GENOTYPE.js
  3. CRC_view_LRGSTR.js
  4. CRC_view_NODATATYPE.js
  5. CRC_view_NUMBER.js
  6. CRC_view_PPV.js
  7. CRC_view_STR.js
  1. You can manually find this line in your webclient/js-i2b2/cells/CRC/ModLabValues/ folder for the 7 files, and replace it:
    Find this:          if (response.transport.statusText=="OK") {
    Replace with:  if (response.transport.status == 200) {


You can try out #2 with only your CRC_view_ENUM.js file for now (Line 35), but you'll want to make the change for all the value type files. This should fix your issue.


Hope this helps,

Hi Jeff and Joseph, 

Thanks a lot for the quick follow-up on this! I'm glad it has been worked through already. We'll explore the solutions and let you know if that does not work.

Mike merged the pull request to master in December (https://github.com/i2b2/i2b2-webclient/pull/12).  I think the changes will be in the next release, but I'm not sure what the schedule is.
