I’m creating a custom extension. On one of my custom properties I want to allow the user to configure a call back function to perform formatting of a map info window. I tried formatting it as a string/textarea but it only seems to allow a limited number of characters for the input. I tried setting the maxLength to 4000 but it didin’t seem to make a difference. I checked the documentation and I couldn’t find a specified limit on the length of string that can be stored but it seems to limit it.
I also tried setting it with expression=”optional” so that I could use the expression box to enter my function. This didn’t work either since it seems to validate the expression even when I use ‘optional’
Do you have any information on how I can format a custom property with a large number of characters?
