Has anyone else encountered an HTTP Code: 500 error while editing an Interface containing only a gridRowLayout?
I have seen this occur several times across multiple different applications. All applications were local installs.
The interface object becomes no longer accessible from the application in /design. The only solution I've found is deleting the object and remaking it.
Discussion posts and replies are publicly visible
Update: This happened again, rendering the object completely unable to edit. It was an interface that contained a gridRowLayout() object. The code did not contain an empty a!dropdownField(). When attempting to re-open the object from /design (after salvaging what code I could from the expression editor), it simply gives the same error and does not allow me to see the interface editor at all.
Hello!
In addition, you can shutdown and restart the processes using the following commands on CMD:
start:
<APPIAN_HOME>\services\bin\start.bat -p password -s all
<APPIAN_HOME>\data-server\bin\start.bat
<APPIAN_HOME>\search-server\bin\start.bat
<APPIAN_HOME>\bin\jboss\jboss-eap-6.4\bin\standalone.bat
shutdown:
<APPIAN_HOME>\bin\jboss\jboss-eap-6.4\bin\shutdown.bat
<APPIAN_HOME>\search-server\bin\stop.bat
<APPIAN_HOME>\data-server\bin\stop.bat
<APPIAN_HOME>\services\bin\stop.bat -p password -s all

alexandral I just made an experiment, don't insert a!dropdownField. Add a!dropdownField().
Root cause is that when you add a component name (here a!dropdownField) without brackets this will cause this pink error with HTTP Code : 500.
Solution when you type the component name either select the component from the suggestion or type the name with brackets.
Look at the attachment I have reproduced the error with a!textField.
