I get a "Illegal argument expression" after trying to get SMP/E environment information (getting an overview of received / installed ptf's)
Additional Diagnostic Data:
A severe error has occurred on the server - IllegalArgumentException.
Please contact CA support.
Microsoft Internet Explorer 11
The problem at GWT has been described at StackOverflow, see http://stackoverflow.com/questions/32840678/gwt-in-firefox41-repetitively-encodes-token-in-url
An alternative is upgrade GWT, that is a big deal and probably not suitable for this particular case.
For users with Firefox having this problem:
Go to Configuration, type ‘about:config’ into the location bar (instead of a URL)
Confirm ‘I promise to be careful’ dialog if appears.
Search for the ‘dom.url.getters_decode_hash’ key
And set the value to ‘true’
For users with MS IE 11 having this problem:
Use another browser, or earlier version of MS IE.
MS IE 11 is not support by CSM.
