Anyone know what the max character count is for a data display? I hit a wall on it displaying after 2200 characters.

Thanks

I looked at the Creating Clinical Content document and it really didn't say. Said a max of 20 lines. Most other types of fields showed a max of 2000 characters when any max was specified.

2k seems to be a magic number since most of the database fields are not any larger than that.

Depends on how you are "feeding" the data display. OBS and doctemps have a 2K limit. Global variables don't have this limit but, if scoped at the encounter level, will "disappear" when the document is put on hold. You can, of course "refresh" a gbl if it's NULL.

So, if you put, eg, {document.temp_1 + document.temp_2 + document.temp_3 + ...} as a MEL expression type of connection, it should all "show" even if the size of the concatenated string is > 2K.

What I am doing it pulling in just strings of text based of a document variable selection.

An If then else scenario.

All of them work except one and I originally thought it was a text lenght issue but now I am wondering if it is due to several special characters in the text. I am going to remove those and see how it works and I will respond back after I have done that.

Okay, Figured it out. Not special characters but [ ] are culprits. Data displays do not like them at all.

Just wanted to update the thread.
