Hi Erik,

If model item properties could still be applied to xxforms-readonly instances this would expand the number of scenarios it could be used in. For example, we use forms containing only xf:outputs to present data, but we still need the datatype & relevance properties to present the data correctly.

However I suppose in implementing full MIP support you might lose the performance gain of xxforms-readonly, which is the whole point.. ?

Doug,

Well, hard to say if it's really a feature, but the answer is that at the moment you can't use model item properties with a read-only instance:

Hi,

 

We have a problem when we set a xxforms:readonly instance to be bind readonly  I know it seems an odd thing to do but it happens in our application when we want to make a printable version of the page we set all the instances to readonly,

 

Is this a bug or a feature ?

 

Also it would be really helpful if the “Cannot modify read-only instance” message told you which instance it was.

 

  The attached file shows the problem.

 

regards

Doug
